YOCH Electrical Insulated Bearing 6420M/C3VL0241 Insulation Bearings Deep Groove Ball Bearings for Traction Motors

Deep groove ball bearings are the most widely used bearing type and have the most comprehensive functions. The low-friction are optimized for low noise and vibration for high rotational speeds. It can bear radial load and axial load in both directions, easy to install, and requires less maintenance than other types of bearings.
Deep groove ball bearings especially in electric motors. These non-separable bearings are suitable for high speeds. The deep uninterrupted raceway grooves have a close osculation with the balls, enabling the bearings to accommodate radial loads and axial loads in both directions.
Deep Groove ball bearings are the most popular of all the ball bearing types because they are available in a wide variety of seal, shield and snap-ring arrangements.The bearing ring grooves are circular arcs made slightly larger than the radius of the ball.The balls make point contact with the raceways (elliptical contact when loaded). The inner ring shoulders are of equal height (as the outer ring shoulders).
Deep Groove ball bearings can sustain radial, axial, or composite loads and because of simple design, this bearing type can be produced to provide both high-running accuracy and high-speed operation. Standard ball retainers (cages) are made from pressed steel. Machined cages are used in bearing operation at very high speed or for large diameter bearings.
