The weights and forces that are applied in electric motors and vehicles in general require high-performance parts. A wide variety of bearing types are used to bring the moving parts together. These include deep groove ball bearings, angular contact ball bearings, cylindrical roller bearings, spherical roller bearings, CARB toroidal roller bearings and spherical roller thrust bearings. 

Design requirements and operating conditions of the parts typically determine what type of bearings are used. For more heavy duty applications with heavy loads, roller bearings are used, and for smaller machines, deep groove ball bearings. In any case, the friction, speeds and temperatures that are generated in these parts makes premature bearing failure a real possibility and a constant risk if they are not of the right quality. Therefore, the precision and surface finish of the electric motor bearings becomes exceptionally crucial. 

PIB provides small electric motor bearings with the level of precision needed in these use cases to minimize friction, and ensure that the parts demand a low level of maintenance. In addition, our inventory includes a comprehensive range of high-performance lubricants specifically developed to withstand the operating conditions that electric motors are subjected to.
