Temperature, ventilation or suspension dynamics – a lot can be adjusted in the car by means of various rotary controls. Here, the new xiros type 67 and 68 thin ring bearings are particularly suitable since an extremely low weight is crucial and usually only a small space is available. The motion plastics specialist igus offers this in two different materials (xirodur B180 and xirodur S180) in inner diameters between four and 30 millimetres. Special dimensions or customer-specific integrated solutions are also possible on request.
For both xirodur materials, users can choose between balls made of stainless steel 1.4401 or glass, whereby the use of glass balls guarantees a completely non-magnetic version of the ball bearings. In addition, the use of plastic balls is possible on request for a further weight reduction.
Maintenance-free and light-weight
The xiros thin ring bearings from igus are suitable for application temperatures between -40 degrees Celsius and +80 degrees Celsius. They do not require lubrication and are corrosion free. In the largest test laboratory for plastics in motion at igus with a floor area of 2750 square metres, various rotating and pivotingl tests have proved that the bearings are suitable for several 100 million cycles within permissible loads.
“As in all xiros ball bearings, the frictional torque of our thin ring bearings is also very low,” says Marcus Semsroth, head of the xiros ball bearings division at igus. “Thus, no breakaways can be felt when they are moved, which, for example, ensures very good haptics when used on rotary contols.”
