Roller bearings
Innovation in Motion
The key difference between a conventional ball bearing and a Franke wire race bearing lies in the race rings. In a wire race bearing, the rolling elements do not roll on solid housing rings, but on hardened wires. The flexibility of this principle makes it possible to design more freely and simply in order to develop better products. Thanks to their patented technology, Franke wire race bearings offer maximum design freedom without having to compromise on load capacity.
Even the standard range of Franke wire race bearings and slewing rings offers a high degree of variability. The rotational resistance of a Franke bearing is adjustable and can be adapted to requirements. Elastomer inserts between the housing and races decouple the bearing and prevent the transmission of structure-borne noise for particularly low noise generation. Many other parameters such as material, housing shape or the nature of the rolling elements can also be varied and adapted to the application. This results in customised solutions with the greatest possible benefit.
Sustainable and efficient: direct drive (torque)
Energy efficiency, dynamics and high precision components are becoming increasingly important in many industries. Precision bearings from Franke fulfil the highest demands in these categories. Be it in medical technology in the development of ever more powerful computer tomographs or in mechanical engineering in workpiece positioning for increasingly complex processing steps.
Franke slewing rings with direct drive are characterised by maximum energy efficiency. The integration of the drive motor directly into the bearing makes it possible to dispense with components such as gears and drive pinions and therefore complex lubrication circuits. The moving masses are significantly lower and power loss due to friction is minimised. Slewing rings with segmented direct drive set new standards in terms of performance and service life. The integration of the wire race bearing in a motorised direct drive overcomes the traditional limits of vertical bearing applications.
Special feature: overcoming gravity
The key special feature of the bearing with integrated segment motor is the electromagnetic force of the motor acting upwards on one side. This reduces the force of gravity acting on the rotor, which relieves the integrated bearing of the weight of the rotor. The result is a relieved mode of operation and thus a considerably longer service life compared to conventional roller bearings.

Advantages: Longer service life and contribution to sustainability
The advantages of this innovative bearing solution are manifold. In addition to their impressive service life and extended maintenance intervals, slewing rings with segment motors make a significant contribution to sustainable design. By reducing wear and optimising operation, they help to conserve resources and minimise the ecological impact.
What makes the product intelligent?
The special feature of the bearing with segment motor is the electromagnetic force of the motor, which is directed upwards on one side. This force reduces the gravitational force acting on the rotor, which significantly relieves the integrated bearing of the weight of the rotor. The result is much more efficient operation and a significantly longer service life compared to conventional roller bearings. Segment motor bearings therefore help to optimise the overall system performance.
Applications: Highly dynamic rotary movements
In devices and machines such as processing machines and computer tomographs, rolling bearings are used vertically at high speeds. The highest demands are placed on performance, slewing rings with segment motors are ideal for these scenarios thanks to their precise and low-load operation. In modern computer tomographs, rotating loads of up to 1 tonne are used. The main bearing of the computer tomograph is also responsible for ensuring that precise images are delivered. Even at high speeds, it must run quietly and with low vibration. Precise radial and axial run-out must be guaranteed. Franke special bearings for computer tomographs achieve speeds of up to 400 rpm with a noise level of less than 60 dB (A). Their high precision and smooth running ensure excellent images through the X-ray unit.
Pioneer in the field of advanced storage technologies
The fusion of innovation and technical excellence in slewing rings with segment motors redefines the standards in the bearing industry. This development not only promises efficiency and precision, but also paves the way for a more sustainable future in industrial manufacturing.
