Product Details
Key Features & Technical Highlights
| Description | Value / Benefit |
|---|---|
| Self-Aligning Function | Automatic heart adjustment compensates for shaft misalignment up to ±2° — extends service life by 30% vs. standard thrust bearings |
| Bearing Model & Standard | BDL 29348 (ISO 293 series) — fully compatible with SKF 29348 interchange specs |
| Dimensions (mm) | 95 × 170 × 32 — optimized for locomotive gearbox & traction motor mounting |
| Precision & Clearance Options | P0–P2 accuracy grades; C0/C3/C4 clearance — ensures low-noise, high-stiffness operation under dynamic loads |
| Cage Material | Steel or brass cage — superior strength and thermal stability in continuous-duty rail applications |
| 60° — delivers exceptional axial load capacity (Ca = 1,120 kN) and radial support synergy | |
| Material & Hardness | GCr15 bearing steel, 61–64 HRC — meets ISO 683-17 & EN 10088 standards |
| OEM/ODM Support | Full customization: laser marking, special lubrication, packaging — backed by ISO 9001-certified production |
| Origin & Compliance | Made in China; HS Code 8482101000 — compliant with EU RoHS & REACH for global rail supply chains |
| Lead Time | 10–15 days — faster than OEM lead times (typically 8–12 weeks), with real-time stock visibility |
Engineered for heavy-haul locomotives, metro drive systems, and industrial gearboxes — this self-aligning roller bearing eliminates installation stress, reduces maintenance frequency, and sustains peak performance at 1,500–3,000 rpm. Unlike generic alternatives, BDL 29348 features precision-ground raceways, symmetrical roller profiling, and micro-polished surfaces — verified via 100% ultrasonic testing and dynamic load validation.
FAQ: Q: Is pre-lubrication included? A: Yes — filled with SKF LGEP 2 grease (NLGI 2, -30°C to +130°C). Q: Can it replace SKF 29348 directly? A: Yes — identical footprint, tolerances, and load ratings. Q: What’s the max static axial load? A: 2,850 kN (per ISO 76).
