What types of bearings are used in electric motors & generators?

Electric motors and generators use a wide variety of bearing types includ-ing deep groove ball bearings, angular contact ball bearings, cylindrical roller bearings, spherical roller bearings, CARB toroidal roller bearings and spherical roller thrust bearings.

How to replenish grease lubricated bearings in electric motors?

For replenishment of grease lubricated bear-ings in electric motors, use the motor manu-facturer’s recommendations, if available. Other wise, suitable quantities for replenish-ment from the side of a bearing (like for deep groove ball bearings or cylindrical roller bear-ings) can be obtained from B = bearing width [mm].

What type of bearing should a SKF motor use?

In these cases, the load is accommodated by the non-drive bearing in the motor and the bearing supporting the coupled shaft. For these types of applications, SKF recommends using a spring loaded deep groove ball bearing in the non-locating position.

What is SKF certified rebuilder electric motor?

SKF Certified Rebuilder Electric Motor is a program designed by SKF to satisfy industrial users’ demands for the most reliable repair operations; it focuses on identifying the root cause of bearing damage, the world class repair methods and the electrical and mechanical motor conformance tests that allows the motor to achieve optimum performance.

How do you install a bearing on an electric motor?

Make sure that the bearing is mounted at a right angle onto the shaft/into the housing. Apply the mounting force to the appropriate ring. The non-separable bearings typically used in electric motors are deep groove ball bearings, single row angular contact ball bearings, CARB toroidal roller bearings and spherical roller bearings.

Can SKF explorer bearings be used in electric motors?

Bearings in the 62 and 63 series are typic-ally used in electric motors. However, from the calculations above, it is clear that when electric motor designers want to downsize, they can achieve this by using capped SKF Explorer bearings with the appropriate grease.
