Key Features & Technical Highlights
| Description | Core Value |
|---|---|
| Spherical self-aligning design | Compensates for shaft misalignment up to ±2.5° — extends service life in harsh mining/agricultural environments |
| Double-row roller construction | High radial & moderate axial load capacity — ideal for heavy-duty rotating equipment |
| 160×290×80 mm dimensions (d×D×B) | Precise OEM fit for common gearboxes, crushers, harvesters, and conveyors |
| Bearing steel (GCr15) + heat-treated cage | Superior hardness (HRC 60–64) and fatigue resistance vs. standard carbon steel |
| Multiple precision grades (P0–P2) | Ensures low vibration & noise — P5/P4 available for high-speed applications |
| Adjustable clearance (C0/C3/C4) | Optimized thermal expansion control — C3 most popular for industrial machinery |
| Grease or oil lubrication compatible | Flexible maintenance — supports long-interval relubrication with lithium-based grease |
| Unseparated, robust cage (E4-type pressed steel) | Enhanced roller guidance & reduced skidding — improves reliability under shock loads |
| OEM/ODM support + BDL branding (China origin) | Fully customizable specs, packaging, and marking — backed by ISO 9001-certified production |
| HS Code 8482300000 | 1M pcs/year capacity | Fast lead time & global compliance — ready for bulk export and project supply |
Engineered for extreme conditions: used in jaw crushers, rotary tillers, grain augers, and vibrating screens. Unlike generic imports, these bearings feature tighter raceway geometry tolerances, optimized roller profiles, and 100% dimensional inspection. FAQ: Q: Can it replace SKF 21305 EAE4? A: Yes — identical interface & performance; superior cost-efficiency. Q: Is C3 clearance standard? A: Yes, unless specified otherwise. Q: What’s the max speed with grease? A: ~2,200 rpm (with proper sealing & cooling). Ready to request a quote or sample? Contact us now — our engineers respond within 2 hours.
