Overview
INA GE90-DO-2RS Spherical Plain Bearing is a sliding-contact bearing that allows oscillating motion and misalignment. It supports high radial and changing-direction loads, making it suitable for hydraulic cylinders, linkages, construction machinery, and agricultural joints.
A spherical inner ring slides against a matching spherical outer ring. Maintenance-required, maintenance-free, and sealed designs can be selected according to load, speed, and service conditions.
Key features
- Suitable for oscillating and tilting motion
- Allows misalignment
- High static load capacity
- Maintenance-required and maintenance-free options
Typical applications
- Hydraulic cylinder rod ends
- Construction machinery linkages
- Agricultural joints
- Industrial pivot structures
Selection guidance
Check load direction, oscillation angle, relubrication access, sealing need, ring material, and mounting dimensions.
