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 heat resistance for continuous-duty rail applications |
| Contact Angle | 60° — delivers exceptional axial load capacity (up to 1,280 kN static) with minimal radial deflection |
| Material & Hardness | GCr15 bearing steel, hardened to HRC 60–64 — meets ISO 683-17 & DIN 17230 standards |
| OEM/ODM Support | Full customization: laser marking, special grease (e.g., SKF LGEP2), packaging — backed by ISO 9001 certified factory |
| Quality Assurance | 100% dimensional inspection + noise testing; 2-year warranty against material/workmanship defects |
| Rail-Specific Advantage | Designed for EN 15085-2 CL1 compliance — vibration-dampened, corrosion-resistant surface finish |
Engineered for heavy-haul locomotives, metro systems, and high-power traction drives — this self-aligning roller bearing reduces maintenance downtime and eliminates premature failure from misalignment or thermal expansion. Unlike generic alternatives, BDL 29348 features tighter raceway geometry control and optimized roller profiling for uniform load distribution. Frequently asked: “Can it replace SKF 29348 directly?” Yes — identical mounting dimensions, load ratings, and lubrication grooves. “Is brass cage available for high-temp environments?” Yes — standard option upon request.
