Overview
INA 81220 Axial Cylindrical Roller Bearing supports large one-direction axial loads with high rigidity. It is suitable for gearboxes, extruders, presses, and machine tool tables where high thrust capacity is needed in a short axial space.
The bearing is assembled from cylindrical roller and cage assemblies, shaft washers, and housing washers. Its separable structure simplifies mounting, while raceway hardness and finish are important if adjacent components are used as raceways.
Key features
- High one-direction axial load capacity
- High axial rigidity
- Separable design for easy mounting
- Compact axial arrangement
Typical applications
- Industrial gearboxes
- Extruders and presses
- Machine tool rotary tables
- Heavy-duty screw mechanisms
Selection guidance
Check axial load direction, washer configuration, raceway quality, minimum load, lubrication, and speed.
