Key Specifications & Why Engineers Choose This Spherical Plain Bearing
| Description | Core Value |
|---|---|
| Model Range (GEGZ31ES-2RS / 38ES-2RS / 44ES-2RS) | Standardized, globally recognized interchange series — direct SKF-compatible replacement |
| Material: High-Carbon Bearing Steel | Superior hardness & fatigue resistance vs. generic carbon steel — extends service life by ≥35% |
| Self-Lubricating Design (2RS Seals) | No external grease required — ideal for inaccessible or maintenance-critical hydraulic cylinders |
| Radial Load Capacity + Angular Misalignment ≤10° | Stable performance under dynamic shock loads — proven in forging & construction machinery |
| Steel-on-Steel Sliding Contact | Precisely ground surfaces with micro-textured finish — low friction, minimal wear even at high PV values |
| Origin: China (ISO 9001 & IATF 16949 Certified) | Rigorous process control — dimensional accuracy ±0.008 mm, surface roughness Ra ≤0.2 μm |
| Applications: Hydraulic Cylinders, Shock Absorbers, Automation Arms | Engineered for vibration-prone, high-cycle environments — zero seizure in 500k+ stroke tests |
| OEM/ODM Support & Neutral Packaging | Fast customization (logos, specs, packaging) — same lead time as standard orders |
| HS Code 8482101000 | Export-Ready Carton+Pallet | Seamless customs clearance — pre-verified documentation for EU, US, ASEAN markets |
| FAQ: “Is preload adjustable?” “Yes — inner ring can be preloaded via axial adjustment during mounting.” |
“What’s max operating temp?” “120°C continuous (short-term up to 150°C with oil film retention).” |
