The inner and outer ring raceways of deep groove ball bearings have arc-shaped deep grooves, and the channel radius is slightly larger than the ball radius. Mainly used to withstand radial loads and also withstand certain axial loads.
Deep groove ball bearings generally use a two-part steel plate stamping cage, but large-size or high-speed bearings use a solid cage. This cage is guided by the ball like a stamped cage, and the high-speed deep groove ball bearing is maintained. The frame is usually guided by the inner or outer ring ribs.
Deep groove ball bearings are the most common and cheapest type of bearings
