Key Specifications & Advantages of KR22 Rod End Bearing
| Description | Core Value |
|---|---|
| GB/T9161 Certified Spherical Plain Bearing | Meets strict Chinese national standard for dimensional accuracy and load capacity |
| KR22 Model, 100×150×90 mm Dimensions | Optimized size for heavy-duty industrial linkages and control arms |
| Self-Lubricating Steel-on-Steel Sliding Contact | Zero external lubrication needed; ideal for inaccessible or maintenance-sensitive installations |
| Corrosion & Wear Resistant (BDL Brand) | Extended service life in humid, dusty, or mildly corrosive environments |
| Trust + Radial Load Capability | Handles combined axial and radial loads — perfect for robotics, construction machinery & aerospace actuators |
| Thin-Film Hydrodynamic Lubrication | Ensures smooth, low-noise motion with minimal friction even under intermittent operation |
| OEM/ODM Support & Neutral Packaging | Flexible branding and logistics — trusted by global engineering partners |
| 1,000,000 pcs/year Production Capacity | Reliable supply continuity and fast lead times |
| Made in China (HS Code 8482101000) | Cost-efficient without compromising precision or durability |
| High Precision, Low Noise, Long Life | Outperforms generic rod ends in repeatability and fatigue resistance |
Engineered for demanding motion control applications — from agricultural hydraulics to industrial automation — this KR22 rod end delivers SKF-grade reliability at competitive value. Its self-lubricating design eliminates grease ports and maintenance downtime, while GB/T9161 compliance ensures interchangeability and traceable quality. Unlike standard plain bearings, it sustains performance under misalignment and shock loads thanks to hardened raceways and optimized spherical geometry.
FAQ: Q: Is this bearing compatible with ISO 12240-4? A: Yes — dimensions and load ratings align closely; full test reports available upon request. Q: Can it replace SKF GE22ES? A: Dimensionally identical; consult our engineering team for dynamic load validation. Q: What’s the max operating temperature? A: Up to 120°C continuous (steel-on-steel, dry).
