Why Choose These High-Performance Tapered Roller Bearings?
| Description | Key Value |
|---|---|
| Precision & Reliability | P0–P2 precision grades, Z1V1–Z3V3 low-vibration options — ideal for high-speed motors and electric drives |
| Robust Material | High-carbon chromium bearing steel (GCr15), hardened to 60–64 HRC for extended service life |
| Wide Size Range | Bore: 15–240 mm; OD: 35–400 mm — covers 31303, 33205, 33005, 33108, 32904 standards |
| Optimized Load Handling | True tapered geometry delivers superior combined radial + axial load capacity vs. deep-groove bearings |
| Separable Design | Inner/outer rings separable — simplifies mounting, maintenance & OEM integration |
| Proven Application Fit | Engineered for industrial motors, EV powertrains, gearboxes, pumps & electricity distribution systems |
| Quality Assurance | 100% dimensional inspection, noise testing, and batch traceability — compliant with ISO 9001 & GB/T 307.1 |
| Competitive Edge | BDL-branded, China-manufactured — same performance as SKF 300/320 series at ~40% lower landed cost |
| Lubrication Flexibility | Pre-greased (NLGI #2) or oil-lubricated — compatible with common industrial lubricants |
| OEM/ODM Ready | Custom packaging, branding, and spec adjustments available — MOQ from 500 pcs |
FAQ: Are these interchangeable with SKF tapered roller bearings? Yes — dimensional and tolerance specs align with ISO 355. Do they support heavy shock loads? Absolutely — optimized cage design and raceway profiling enhance dynamic strength. What’s the typical lead time? Stock items ship in 3–5 days; custom orders in ≤15 days.
