Key Specifications & Advantages
| Description | Core Value |
|---|---|
| Model: KR62 (part of KR40–KR62 series) | Standardized GB/T9161 compliance — ensures interchangeability & global acceptance |
| Material: Self-lubricating bushing | No external grease needed — reduces maintenance & downtime |
| Bearing Type: Spherical plain bearing | Handles combined radial + thrust loads — ideal for misaligned or oscillating motion |
| Lubrication: Thin-film hydrodynamic | Stable performance under high load & low speed — superior to conventional grease-lubed rods |
| Sliding Contact: Steel-on-steel | Enhanced wear resistance & longevity — up to 2× service life vs. standard bronze bushings |
| Corrosion & Wear Resistance | Surface-treated for harsh environments — suitable for marine, mining, and agricultural machinery |
| Dimensions: 100×150×90 mm | Compact yet robust design — fits space-constrained industrial linkages |
| OEM/ODM Support & Neutral Packaging | Custom branding & logistics-ready carton pallets — seamless integration into your supply chain |
| Origin: China (HS Code 8482101000) | ISO-certified production — 1,000,000 units/year capacity with strict QC at every stage |
| Trademark: BDL (SKF-compatible spec) | Engineered to match SKF’s POSA/PHSA dimensional & performance benchmarks — direct replacement |
Used in construction equipment, hydraulic cylinders, robotics joints, and wind turbine pitch systems. Backed by 18-month warranty and material traceability. Unlike generic rod ends, our KR-series features precision-ground spherical surfaces (<±0.005 mm roundness) and optimized PTFE composite lining — delivering lower friction coefficient (0.08–0.12) and quieter operation.
