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.
