Bearings designed to work in an electric motor have the same characteristics, but with an added bonus: insulation and silence. The real enemy of these models is electrical erosion. They are fitted with an insulating layer to limit damage from passing current and improve their longevity.
Bearings are an essential component of gearboxes as they help to support and reduce the friction between the rotating shaft and the stationary case. They allow the gears to turn smoothly and transmit power from one component to another without damaging the gearbox itself. The correct selection and use of bearings in gearboxes can increase the gearbox's efficiency, reduce maintenance costs, and extend its service life. There are several types of bearings used in gearboxes, including cylindrical roller bearings, angular contact bearings, and ball bearings. Each type of bearing has unique characteristics, and the selection of the type and size of bearing depends on the gearbox's application, load, and operating conditions.
