Plastic Ring Bearing
By Design Engineering staffPower Transmission Machine Building bearing igus
igus self-lubricating xiros bearings designed for confined, weight-restricted applications.
Igus introduced its xiros ball bearings in accordance with DIN 625 for rotary controls. The xiros 67 and 68 thin ring bearings are suitable for temperatures ranging from -40º – 176º F, and are available in two materials (xirodur B180 and S180) with inner diameters ranging from 4-30mm, with custom dimensions and integrated solutions available upon request. Customers can select from glass, 316 stainless steel or high-strength plastic balls depending on application requirements.
The xiros 67 and 68 bearings have been tested to last for more than 100 million cycles (within permissible loads). “As with all xiros bearings, the frictional torque of the new thin ring bearings is very low,” explained Nicole Lang, product manager for plastic bearings at igus Inc. “This allows for excellent haptics when used on rotary controls, since no breakaways can be felt in the movement of the bearings.”
