22208CW33

22208CW33 is a type of spherical roller bearing with an inner diameter of 40mm, outer diameter of 80mm and width of 23mm. It has excellent self-aligning ability and can compensate for misalignment between the shaft and housing. This bearing can bear heavy radial load and double-direction axial load, with good impact resistance and high temperature resistance.
It is widely applied in mining machinery, crushers, speed reducers, fans, cement plant equipment, metallurgical machinery, paper-making equipment, conveyor rollers, agricultural machinery, air compressors and industrial gearboxes, especially working under heavy load, strong vibration and shaft misalignment conditions.
For installation and usage, please clean the bearing, shaft and housing thoroughly before mounting. Hot mounting is recommended for the inner ring; never strike the bearing directly. Keep proper fitting clearance to avoid inner ring creep or bearing locking. Fill with suitable grease or oil and maintain good sealing to prevent dust and moisture ingress. Run the machine at low speed with no load first, then increase load gradually, and replenish lubricant regularly.
Under correct installation, standard lubrication and stable working conditions, its service life can reach 20,000 to 50,000 working hours. Overload, poor lubrication and dusty environment will greatly reduce its lifespan. Proper daily maintenance can effectively extend its service life by more than 30%.
Model Code Explanation:
The letter C represents stamped brass cage with symmetric roller structure, featuring higher load capacity, stable rotational performance and better high-temperature resistance. W33 means the outer ring is designed with an annular grease groove and three lubrication holes, convenient for continuous greasing and suitable for long-term non-stop operation.
