GEG ES MoS2 Coated Phosphorization Treated Steel Steel Angular Contact Spherical Plain Bearing
GEG ES MoS2 Coated Phosphorization Treated Angular Contact Spherical Plain Bearing
The GEG ES is a robust steel-on-steel angular contact spherical plain bearing designed for heavy-duty industrial applications. Featuring MoS2 (Molybdenum Disulfide) coating on the sliding surfaces and full phosphorization treatment, this bearing delivers superior wear resistance and load capacity under extreme conditions. The integrated lubrication grooves and holes enable convenient relubrication for extended service life.
Key Features
- Steel-on-Steel Sliding Surface: Both inner and outer rings manufactured from high-grade carbon chromium steel, hardened for maximum load capacity and durability
- MoS2 Solid Lubricant Coating: Molybdenum Disulfide treatment on spherical sliding surfaces reduces friction and prevents cold welding under high contact pressure
- Phosphorization Treatment: Chemical conversion coating on both rings provides corrosion protection and improved lubricant adhesion
- Relubricatable Design: Lubrication groove and holes in both outer and inner rings allow for periodic greasing to maximize bearing life
- Angular Contact Configuration: Optimized for combined radial and axial loads with high rigidity
- Single Axial Split Outer Ring: Simplified installation and secure fit in the housing
- Self-Aligning: Spherical geometry compensates for misalignment up to the bearing's angular range
