GEFZ25C Radial Spherical Plain Bearing 25.4mm Bore Hard Chromium Plated PTFE Composite Heavy Duty
GEFZ25C Heavy-Duty Radial Spherical Plain Bearing — Hard Chromium Plated with PTFE Composite
The GEFZ25C is a heavy-duty radial spherical plain bearing designed for demanding industrial applications requiring high load capacity with maintenance-free operation. Featuring a robust carbon steel outer ring with integrated PTFE composite sliding surface and a hardened carbon chromium steel inner ring with hard chromium plating, this bearing provides exceptional durability with a dynamic load rating of 69.4 kN and static load rating of 173.5 kN.
Key Features
- High Load Capacity: Dynamic load rating of 69.4 kN and static load rating of 173.5 kN — designed for heavy-duty radial load applications
- Hard Chromium Plated Inner Ring: Carbon chromium steel inner ring hardened and treated with hard chromium plating on the spherical sliding surface for maximum wear resistance under high contact pressure
- PTFE Composite Liner: Self-lubricating PTFE composite material bonded to the outer ring raceway ensures maintenance-free operation with low friction and extended service life
- Carbon Steel Outer Ring: Precision-pressed around the inner ring for secure assembly and consistent dimensional stability under load
- 25.4mm Bore: Standard 1-inch bore size suitable for common industrial shaft dimensions, with large outer diameter for enhanced load distribution
- Angular Misalignment Compensation: Spherical sliding geometry accommodates housing misalignment, reducing system-level precision requirements
- Maintenance-Free: PTFE composite liner eliminates the need for periodic greasing, reducing total cost of ownership
