Maintenance-free and extremely lightweight ball bearings

For confined spaces and where low weight is crucial, igus has developed thin-ring bearings which conform to DIN 625. The xiros plastic ball bearings are suitable for a variety of in-vehicle applications – they are self-lubricating and therefore maintenance-free, as well as having low friction properties.

The bearings can be used in turning dials for adjusting temperature, ventilation or chassis dynamics from in the car. Since weight is minimised to for fuel economy and space is usually at a premium, the xiros thin-ring bearings of series 67 and 68 are said to be particularly suitable.

Available in two different materials (xirodur B180 and xirodur S180) these bearings are offered as standard with internal diameters of between 4 and 30mm. Special dimensions or customer-specific integrated solutions are available upon request. For both xirodur materials, the balls are available made of stainless steel or, for a completely non-magnetic version, glass. To achieve further weight reductions, balls made of plastic are also possible on request.

The xiros thin-ring bearings are suitable for application temperatures between -40 and 80°C. In addition, to them being self-lubricating, they are corrosion-resistant. These bearings have also undergone various tests with results indicating that they are suitable for several hundred million cycles within permissible loads.
