Product Details
Key Specifications & Advantages of GEGZ Spherical Plain Bearings
| Description | Core Value |
|---|---|
| Model Range | GEGZ50ES-2RS / 57ES-2RS / 63ES-2RS — standardized, interchangeable metric series |
| Material & Construction | High-carbon chromium bearing steel (GCr15), whole outer ring for rigidity and sealing integrity |
| Lubrication | Self-lubricating design — no relubrication needed; ideal for sealed or hard-to-access applications |
| Load Capacity | Radial spherical plain bearing with ±10° misalignment tolerance and high static load rating |
| Sliding Pair | Steel-on-steel contact surface — enhanced wear resistance and consistent low-friction performance |
| Applications | Hydraulic cylinders, forging machines, construction equipment, auto shock absorbers, water conservancy systems |
| Precision & Reliability | High-precision ground geometry, low noise, extended service life (tested ≥10,000 hrs under rated load) |
| Quality Assurance | Manufactured in ISO 9001-certified facilities; 100% dimensional & functional inspection; BDL trademark registered in China |
| Differentiator vs. Generic Brands | Tighter tolerance control (±0.008 mm on bore/OD), optimized raceway curvature for load distribution, superior corrosion resistance via controlled surface hardness (HRC 58–62) |
| FAQ | Q: Are these compatible with SKF mounting dimensions? A: Yes — GEGZ series follows ISO 12240-1 standards and matches SKF GE…ES-2RS footprint. Q: Can they replace older GEGZ models without modification? A: Absolutely — identical specification and interchangeability confirmed. |
