GEFZ12C Radial Spherical Plain Bearing 12.7mm Bore Hard Chromium Plated PTFE Composite Self Lubricating
GEFZ12C Radial Spherical Plain Bearing — Hard Chromium Plated with PTFE Composite
The GEFZ12C is a precision radial spherical plain bearing engineered for applications requiring maintenance-free operation with superior wear resistance. Featuring a carbon steel outer ring with integrated PTFE composite sliding surface and a hardened carbon chromium steel inner ring with hard chromium plating, this bearing delivers reliable performance under radial loads with angular misalignment compensation.
Key Features
- Hard Chromium Plated Inner Ring: Carbon chromium steel inner ring hardened and treated with hard chromium plating on the spherical sliding surface for exceptional wear resistance and durability
- PTFE Composite Outer Ring Liner: Self-lubricating PTFE composite material bonded to the outer ring provides maintenance-free operation with low friction coefficient
- Carbon Steel Outer Ring: Pressed around the inner ring for a secure and precise assembly, ensuring consistent performance
- Radial Load Capacity: Designed primarily for radial loads with allowance for angular misalignment — dynamic load rating of 18.4 kN and static load rating of 46 kN
- Compact Design: 12.70mm bore, 25.40mm outer diameter, 12.70mm inner ring width — ideal for space-constrained applications
- Maintenance-Free: PTFE composite sliding surface eliminates the need for relubrication, reducing downtime and maintenance costs
