GAC Series Angular Contact Spherical Plain Bearings (GAC55S GAC60S GAC65S GAC70S GAC75 S GAC80S GAC85S GAC90S)
Spherical plain bearings are used for applications requiring rotation and oscillation. The rotation takes place on a sliding
surface so the limiting speed is slow.
We can supply high quality and almost all types of spherical plain bearing,
- Radial Spherical Plain Bearings
- Angular Contact Spherical Plain Bearings
- Thrust Spherical Plain Bearings
- Non-standard Spherical Plain Bearings
Applications:
Railway engineering
Railway station construction
Bridge building
Construction machinery
Hydraulic steel structures
Roof designs
Power generation
Oil field exploration
Mining and aggregate processing
Wind turbines
Gear drives
Rolling mills
