Product Details
Key Specifications & Advantages
| Description | Core Value |
|---|---|
| Model Range (SA35ES–SA50ES) | Standardized GB/T9161 compliance ensures global interchangeability & OEM acceptance |
| Spherical Plain Bearing Type | Enables multi-directional angular misalignment compensation up to ±15° |
| Self-Lubricating Bushing Material | Zero external grease needed — ideal for inaccessible or maintenance-sensitive installations |
| Steel-on-Steel Sliding Contact | Optimized for high load, low-speed oscillation with consistent thin-film lubrication |
| Corrosion & Wear Resistance | Hardened raceway + PTFE composite liner delivers 2× service life vs. standard bronze bushings |
| Trust & Radial Load Capacity | Simultaneous axial and radial support — critical for construction machinery linkages & robotic joints |
| Neutral Packing + Carton Pallet | Ready for global logistics; meets ISO 8504-2 handling & anti-rust standards |
| BDL Brand, Made in China | SKF-equivalent precision (P5 tolerance) at 30% lower TCO — validated by 3rd-party SGS reports |
| 100×150×90 mm Standard Size | Drop-in replacement for SA50ES applications in agricultural hydraulics, truck suspensions & wind turbine pitch systems |
| OEM/ODM Service Support | Custom marking, special coatings (e.g., zinc-nickel), and drawing-based modifications available within 10 days |
Why engineers specify this series: Unlike generic rod ends, these bearings feature controlled clearance, pre-loaded spherical geometry, and batch-tested load curves — ensuring predictable performance in safety-critical motion control. FAQs: Q: Can it replace SKF SA50ES? A: Yes — dimensional & functional equivalent per GB/T9161–2016. Q: Max operating temp? A: 120°C continuous (lubricant stable). Q: Re-lubrication needed? A: No — self-lubricating design rated for 5,000+ cycles without maintenance.
