The bearings are the most typical rolling bearings with extensive applications. The raceways in both of the rings are in arc groove form, which can carry radial and axial load in double directions. They can be applied in situations where high-rotating speed and low noise and low vibration are required.
Applications
The bearings can be found in automobiles, machine tools, motors, instruments, construction machines, railway vehicles, agricultural machines and various other special machines.
Types
Basic type; With snap ring groove on the outer ring (-N); With one shield (-Z) on one side or two shields (-2Z) on both sides; With one seal (-RS) on one side or two seals (-2RS) on both sides.
