Radial Spherical Plain Bearing GE30ES - INA Brand
Radial spherical plain bearings feature an inner ring with a convex spherical outer surface and an outer ring with a corresponding concave inner surface. This design makes them ideal for applications requiring accommodation of housing misalignment, or where oscillating, recurrent tilting, or slewing movements occur at relatively slow sliding speeds.
Bearing Types
There are two main categories: spherical plain bearings requiring maintenance (steel-on-steel) and maintenance-free spherical plain bearings.
GE30ES Maintenance-Required Bearing Features
- Treated with molybdenum disulphide and phosphated surface coating
- Excellent wear resistance and corrosion protection
- Specifically designed for heavy alternating direction loads
- Ideal for shock loads and heavy static load applications
- Robust steel-on-steel sliding contact surfaces
