Key Specifications & Advantages of BDL Needle Roller Bearings
| Description | Core Value |
|---|---|
| Ultra-compact design (e.g., K20×24×17 mm) | Maximizes space efficiency in tight assemblies — ideal for automotive transmissions, gearboxes & compact industrial actuators |
| Radial load-only, high-load capacity | Supports heavy radial loads with minimal cross-section — 30% higher dynamic load rating vs. standard bushings |
| No inner/outer ring (drawn cup type) | Reduces weight and part count; simplifies mounting on hardened shafts or housings |
| Bearing steel (GCR15 equivalent), hardened & ground | Ensures long service life under high-speed, high-cycle operation |
| Closed-end design with sealed lubrication | Pre-lubricated with premium grease — zero maintenance required for 5,000+ hrs typical duty |
| Precision grades P0–P2 & clearances C0–C4 | Meets SKF/ISO tolerance standards — seamless OEM replacement without redesign |
| HS Code 8482102000 | Made in China (ISO 9001 certified) | Rigorous 100% dimensional & noise testing — consistent quality at 60% lower cost than branded equivalents |
| OEM/ODM support + 3–7 day delivery | Faster lead time than global brands — custom marking, packaging & specs available |
| Grease or oil lubrication compatible | Flexible integration into existing maintenance protocols — no retraining needed |
| 1,000,000 pcs/month production capacity | Guaranteed supply continuity — no stockouts, even for bulk industrial orders |
Engineered for reliability where space, weight, and performance converge — these BDL needle bearings deliver SKF-grade precision and durability at exceptional value. Trusted by Tier-1 automotive suppliers and precision machinery builders worldwide. Have a custom application? Contact us today for technical support and a fast quote.
