Bearing sleeves are essential mechanical components used to adapt, protect, or repair shafts for bearing installation. These cylindrical inserts help secure the bearing to the shaft, ensure a tight fit, and extend the life of both the shaft and bearing by preventing direct contact between moving parts and wear surfaces.

Commonly used in automotive systems, heavy machinery, electric motors, pumps, and conveyors, bearing sleeves play a key role in maintaining alignment, reducing vibration, and enabling easy bearing replacement.
