Electric motor bearings and their appliion - AHR International

Electric motor bearings. The purpose of a bearing in an electric motor is to support and loe the rotor, to keep the air gap small and consistent and transfer the loads from the shaft to the motor. The bearings should be able to operate at low and high speeds whilst minimizing frictional loses. At the same time the bearing must be economic

Fracture tests on aged needle roller bearing cages In the early 1980s, SKF was performing fracture tests on aged PEEK and PA6.6 cages for needle roller bearings. The PEEK cages were aged in air at 180 °C and at 250 °C as well as in Shell Spirax, an EP-enriched oil at 180 °C. For comparative purposes, the PA6.6 cages were aged in air at 180 °C.
