          • Direct drive - Bearing assembly with Torque-Motor

          • Franke bearing assemblies with integrated direct drive (torque motor) are characterized by high dynamics, maximum energy efficiency and a compact installation space combined with center-free design.

            Bearing assemblies with direct drive are suitable for applications where high performance and low space requirements are important criteria. The integration of the drive into the bearing housing means that wear-prone assemblies for transmitting drive power, such as toothed belts, shafts or chains, can be dispensed with. This reduces the required drive energy and also benefits more accurate positioning.

            Why roller bearings with direct drive?

            Franke wire race bearings with integrated direct drive are characterized by highest energy efficiency. The integration of the drive motor into the bearing makes it possible to dispense with components such as gears and drive pinions and thus with complex lubrication circuits. The moving masses are therefore significantly lower and the loss of performance due to factors such as friction and play is minimized.

            Functionality of Franke roller bearings with direct drive

            Torque motors are integrated directly into Franke bearing assemblies. The customer receives a completely ready to install system. This makes it possible not only to generate a rotational movement, but also to position or execute definable cycle steps.

            The torque motor has a high torque at a defined speed range. The distance between the stator and rotor (air gap) is decisive for the magnitude of the torque. The preloaded Franke bearing assembly guarantees a constant air gap. A measuring system can be used to determine the motor position.

          • Alternative materials

          • One of the most promising technologies is 3D printing. This opens up completely new possibilities in design. Franke Wire Race Bearings can be easily integrated into 3D printed housings.

            Special materials for special properties

            The use of alternative materials in bearing constructions as well as state of the art production technologies allow Franke bearings to be optimally adapted to the application. The material used influences properties such as:

            • the weight,
            • the load capacity and robustness,
            • the suitability for certain environments (dirt, humidity, clean room, vacuum, food).

            Materials

            • Aluminium - over 50 % lighter than steel
            • Carbon (CFK) - 75 % lighter and highly resilient
            • Plastic - 80 % lighter, durable and quiet
            • 3D printing - 90 % lighter and very variable

            • Franke solves challenging rotation task for vegetable spiral cutters from company Kronen

            • A challenge becomes a success story: After previously working on a solution with several suppliers, Kronen GmbH finally found the partner in Franke who mastered a difficult rotation task with a sophisticated bearing assembly.

              Franke with a new design approach

              Where standard bearings reach their limits due to customer-specific requirements, Franke offers more advanced solutions with its flexibly adaptable wire-race bearings. In the case of the Kronen project, several problems had to be solved at the same time: heat generation, speed, hygiene, tightness, smooth running and long service life. Franke succeeded in meeting all these requirements with a customised bearing assembly using Franke wire-race bearing technology. The Franke bearing assembly guides the rotating cutting tool. The cut product is transported away through the center of the bearing assembly. The Franke solution is "the first that meets all the criteria and also lasts for a long time", explains Sebastian Serrer. "Moreover, the machine is very fast, the speed goes up to 690 rpm. It took some fiddling around and constructive ideas until we found a solution. Especially since we also had to deal with the problem of contamination and cleaning. The bearing had to be tight, otherwise the service life of the machine would be rapidly reduced," explains Michael Bärstecher, technical advisor at Franke.

            • The great freedom of tube processing - with laser tube cutting machines from Trumpf

            • "Pipes choose Trumpf" is the title of an advertising brochure for Trumpf laser pipe cutting machines. The Swabian flagship company is a global leader in laser processing. Customer-specific wire race bearings by Franke are used in the chucks of its fully automatic cutting artists.

              Innovative clamping with Franke bearings

              A laser tube cutting machine from Trumpf is a high-tech product packed with innovative ideas. This also includes the clamping technology. It is designed in such a way that the time required for set-up is reduced to zero and tedious reclamping is eliminated. The two chucks of a TruLaser Tube machine are fitted with customised double bearings from Franke. "The chucks are central components of our machines," says development engineer Holger Biener. "They have to ensure that the component is positioned exactly. This is the only way to ensure accurate machining." In this context, the Franke double bearings fulfil an elementary function, because any inaccuracy in the bearing would immediately affect the accuracy of the machining. In addition, high reliability is required of the bearing. They are very satisfied with Franke bearings in this respect, reports Markus Stapf: "The good thing about the Franke product: It works - we have no problems at all during assembly or in the field."

            • Lightweight bearings: 3D printing is revolutionizing manufacturing

            • The wire race bearings integrated in an enclosing housing absorbs forces from all directions. In order to adapt wire race bearings to the requirements of the application, there are numerous options with regard to wire profile, bevel, ball diameter and material. By using lightweight materials and the latest manufacturing techniques, lightweight bearings from Franke enable substantial weight, energy and space savings with comparable rigidity and maximum precision over the entire service life.

              The advantages are apparent:

              • Alternative materials such as 3D printing, high-strength plastic or carbon enable significant weight savings.
              • Low moving masses ensure energy efficiency and smooth running.
              • A free design of the surrounding construction enables savings in connected assemblies.
              • Many lightweight materials have positive secondary properties, such as low material expansion or non-magnetism.
          • Bearing Elements

          • Four wires for better design

            The decisive difference between an ordinary ball bearing and a Franke wire race bearing is in the raceways. In a wire race bearing, the rolling elements do not roll on solid housing rings, but on high performance wires. The flexibility of this principle makes it possible to design more freely and simply, in order to develop better products.

            Runs precisely. And runs precisely. And runs precisely.

            In wire race bearings, the raceways of the rolling elements are precisely matched to the diameter of the rolling elements. This ensures optimum functional characteristics and guarantees both, precise running and a long operating life.

            Shock and impact elastic

            The races of Franke wire race bearings are made of hardened spring steel. Shocks and vibrations are absorbed by them. The result: a high resistance against such disturbing influences.

            Compensates deformations

            Slight deformations of the enclosing structures, for example due to temperature changes, are compensated by the flexible Franke bearing element. Where other roller bearings fail, the Franke bearing continues to roll.

            No bearing play. Adjustable rotational resistance.

            Does your application focus on dynamics or precision? Or does a good compromise have to be found? The rotational resistance of a wire race bearing is adjustable. Suitable for each application. At any time.

            Possibilities instead of specifications

            Franke bearing elements can be used in a wide variety of designs. The demands on the enclosing construction are low, because it is not directly exposed to the loads. The main load is borne by the wire race bearing. This allows you to determine almost freely the ideal shape and material of your further construction.

            • Maximum possible integration capacity
            • Series application to meet cost constraints
            • Greatest possible flexibility based on preload, runnability and diameter ranges
            • Infinitely variable from 70 to 2000 mm
              • Bearing elements with a ground raceway Type LEL

              • Franke bearing elements type LEL meet the highest demands with regard to running smoothness, accuracy and rotational speed.

                Franke bearing elements of type LEL are suitable for high demands on running characteristics and accuracy. Due to the hardened and CNC-ground raceway as well as the ideal geometrical adaptation of ball and raceway radius, they have outstanding bearing characteristics. Bearing elements of type LEL allow the greatest possible freedom of bearing design. The mounting space is between 5.9 mm and 20.9 mm. For special requirements, raceway thicknesses up to 20 mm and ball sizes up to 50 mm are possible.

                      Bearing solution used
                      Bearing element LEL (customized)

                      Advantages
                      To further minimize noise, the ball cage of the bearing is only fitted with every second ball. To facilitate series assembly by the customer, the injection-moulded housing has been optimised. A threaded ring is used to adjust the bearing seat.

                    • Beverage Bottling

                    • Requirements
                      Precise fill quantities of non-carbonated beverage products are filled in plastic bottles with the highest microbiological and hygienic safety. At the core of the machine is a filling tube, the inlet opening has a diameter of 40 to 100 mm depending on the size of the filling line. The carousel is filled via the column. The column is supported by one fixed and one floating bearing each. The bearings used must be lubricant-free and corrosion-resistant.

                      Solution
                      Bearing assembly type LDC 250 as 2-row angular ball bearing.

                      Bearing solution used
                      Bearing Assembly LVG (customized)

                      Advantages
                      The bearing assembly is designed as a food-grade, corrosion-resistant stainless steel version with balls made of oxide ceramics. The bearing runs at a speed of 10 rpm and has a radial and axial run-out of 0.03 mm. Axial forces of 1500 N, which act through the filling tube, are absorbed by the bearing. Every 48 hours the components are heated to 130 °C to kill germs. In order to meet the hygienic requirements, the bearing assembly is lubricant-free or has a special lubrication with food grade grease.

                  • Linear Movement

                  • Uniquely dynamic. Uniquely individual.

                    Franke linear systems transfer the ingenious principle of the wire-race bearing to linear movements. Inserted raceways ensure the load capacity on all sides. The rest of the construction can therefore be made of lightweight aluminum. Large guided rollers ensure smooth running - maintenance-free over the entire service life. Thanks to their modular design, Franke linear systems can be individually adapted to requirements.

                      • Accelerate more easily

                      • Franke linear systems are the first choice when highest dynamics are required. The large rollers are mounted very smoothly. They run with low friction and precisely guided on the inserted tough and hard steel wires. Because almost exclusively light aluminum is used for the entire construction, the moving mass is low. The result: Highest dynamics and energy efficiency.
                      • Designing homogeneously with aluminum

                      • The main components of Franke linear systems - rails and cassettes - are made of aluminium. Franke linear systems are ideally suited for constructions made of aluminum, because the homogeneous materiality excludes temperature-related distortions.
                      • The quieter the better

                      • Where Franke linear systems are used, you hear almost nothing from them. Only a quiet, homogeneous noise can be heard. This makes them ideally suited for noise sensitive applications. Furthermore, the whisper-quiet operation is an audible quality feature.
                      • Highly accurate and durable

                      • Franke's core competence lies in the high-precision manufacture and machining of wire raceways. The pursuit of precision determines every single step of our work. The result is bearing solutions with outstanding accuracy values and an excellent service life.
                      • Patented guidance

                      • Franke track rollers have a groove adapted to the wire tracks. This patented type of guidance prevents the rollers from sliding on their bearing pins and rubbing against the housing. The advantage: a lower friction, more controlled movement.
                      • Loadable on all sides

                      • The rollers are arranged crosswise and run on one of the four wires each. In this way, forces are absorbed on all sides and the installation position can be freely determined. Depending on the profile rail used, the bearing can be designed with an external guide in an O arrangement (figure right) or with an internal guide in an X arrangement.
                      • Maintenance-free - carefree

                      • The needle or ball bearings used in the rollers are lubricated for life. This means that no maintenance is required over the long life of a Franke linear guide. For applications in the food industry we also offer lubricant-free roller bearings.
                      • Always the right sliding resistance

                      • The sliding resistance of Franke linear guides can be adjusted to the application at any time using an adjusting screw. Very fine adjustments are possible. This allows the system to be adapted to the load - in the direction of smooth running or in the direction of stiffness and vibration resistance.

                                      Advantages

                                      The guide FDZ12 runs evenly, quietly and cleanly. The elevated preload (0.6 to 0.8N) ensures that the secondary panel travels free from oscillation. The guide comes with lifetime lubrication. The sealed, single-row ball bearings mean that no lubricant can leak to the outside.
