Key Specifications & Advantages of GEWZ Spherical Plain Bearings
| Description | Value / Advantage |
|---|---|
| Model Range | GEWZ19ES-2RS to GEWZ31ES-2RS — precision-engineered for interchangeability and global OEM fit |
| Material & Construction | High-carbon bearing steel (GCr15) with whole outer ring — superior hardness, wear resistance & dimensional stability |
| Lubrication | Self-lubricating design — zero maintenance, ideal for inaccessible or harsh-environment applications |
| Load Capacity | Radial spherical plain bearing — handles misalignment up to ±4° and heavy static/dynamic radial loads |
| Sliding Pair | Steel-on-steel contact with optimized surface finish — high PV value, low friction, consistent torque |
| Applications | Hydraulic cylinders, construction machinery, forging presses, automotive shock absorbers, water conservancy systems |
| Quality Assurance | Manufactured to ISO 1207 & DIN 635-2; 100% dimensional inspection + load testing; BDL trademark certified in China (HS Code 8482101000) |
| Differentiation vs. Generic Brands | Higher precision (±0.01mm tolerance), longer service life (+35% vs. standard), lower noise (<35 dB at 1,800 rpm) |
| Compliance & Support | OEM/ODM ready; neutral packaging; carton-pallet shipping; full traceability & test reports available |
| FAQ: Can it replace SKF GE… series? | Yes — GEWZ series matches SKF GEWZ dimensions, load ratings & mounting interfaces; cross-reference sheet available upon inquiry |
