Key Specifications & Benefits of BDL Needle Roller Bearings (K16X21X10 / K16X22X12 / K16X22X13)
| Description | Core Value |
|---|---|
| Ultra-compact design: 16×21×10 mm, high load capacity in minimal space | Ideal for tight-mounting applications like automotive transmissions and precision gearboxes |
| Radial-only load support with high rigidity | Optimized for high-speed, low-friction radial motion — reduces heat buildup |
| Bearing steel (GCr15) construction | Superior hardness & fatigue resistance — extends service life by up to 30% vs. standard carbon steel |
| Ringless design (no outer/inner ring) | Direct shaft/housing mounting saves weight, cost & assembly time |
| Precision grades P0–P2 & clearances C0–C4 | Meets SKF-equivalent tolerances — seamless OEM replacement |
| Closed-type sealing | Retains grease, blocks contaminants — ideal for dusty or intermittent-lubrication environments |
| Grease or oil lubrication compatible | Flexible maintenance — supports long-interval servicing per ISO 281 |
| Manufactured in China under ISO 9001 & IATF 16949 | Consistent batch quality — full traceability & 100% dimensional inspection |
| BDL brand — 1M units/month capacity | Fast 3–7 day lead time vs. 4–8 weeks for many EU/US alternatives |
| HS Code 8482102000 — globally compliant | Smooth customs clearance — pre-verified for EU, US, ASEAN & Middle East markets |
Why engineers choose BDL over generic needle rollers: Higher dynamic load rating (Cr), tighter raceway roundness (<0.8 μm), and optimized roller end geometry reduce edge stress — proven in 500k+ cycles under 12 kN radial load. FAQ: Q: Can these replace SKF NK16/10? A: Yes — identical dimensions & performance; test reports available. Q: Are custom clearances (e.g., C5) possible? A: Yes — MOQ 500 pcs. Q: What’s the max operating temp? A: 120°C continuous (with lithium complex grease).
