Description
Key Features & Technical Highlights
| Description | Value / Benefit |
|---|---|
| Self-Aligning Function | Automatic heart adjustment compensates for shaft misalignment up to ±2° — extends service life by 40% vs. standard thrust bearings |
| High-Precision Rating | P0–P2 grades available — ensures ultra-low vibration & noise in locomotive drivetrains |
| Optimized Contact Angle | 60° design delivers superior axial load capacity (Ca = 1,120 kN) and rigidity |
| Dual-Row Construction | Double-row tapered roller configuration supports heavy bidirectional thrust loads |
| Robust Materials | High-carbon chromium bearing steel (GCr15), hardened to HRC 60–64 |
| Cage Options | Steel (standard) or brass (high-temp/low-friction) cages — both ISO-compliant |
| Dimensional Accuracy | 95×170×32 mm (d×D×T); tight tolerances per ISO 199 & DIN 616 |
| Proven Locomotive Use | Validated in traction motors, gearboxes & bogie systems under EN 15085 & UIC 515-2 |
| Quality Assurance | 100% dimensional inspection + dynamic load testing; traceable batch certification |
| BDL vs. Generic Brands | Lower torque loss (≤3.2 N·m), 25% longer L10 life, and certified OEM compliance — not just “equivalent” |
Engineered for rail reliability: This BDL 29352D self-aligning thrust bearing eliminates costly downtime from misalignment-induced wear. Its dual-row geometry, precision-ground raceways, and thermal-stable cage deliver unmatched performance in high-vibration, high-load locomotive applications — where SKF-grade consistency matters most. Backed by ISO 9001 manufacturing and full test reports. Need technical validation or custom clearance (C3/C4)? Contact us today for your project-specific datasheet and lead time.
