Product Details
Key Specifications & Benefits of BDL Hard Crane Hook Thrust Ball Bearings (51330–51340)
| Description | Core Value |
|---|---|
| Model Range | 51330 / 51332 / 51334 / 51336 / 51340 — precise interchangeability with SKF 51300-series thrust bearings |
| Load Capacity | High axial load support (up to 380 kN), engineered for crane hook & heavy-lifting applications |
| Precision Grade | P0 to P2 tolerance — exceeds ISO/ABEC standards, ensures smooth rotation under dynamic loads |
| Vibration Class | Z1V1–Z3V3 certified — ultra-low noise & vibration for precision hoisting systems |
| Material & Hardness | GCR15 bearing steel, HRC 60–64 — superior wear resistance and fatigue life vs. standard carbon steel |
| Lubrication Flexibility | Compatible with both grease & oil — ideal for sealed or circulating lubrication systems |
| Design Type | Non-aligning, separable single-row thrust bearing — simplifies installation & maintenance on crane hooks |
| Dimensions (mm) | 150×250×80 — direct fit replacement for SKF 51334/51340 in industrial cranes and winches |
| Quality Assurance | ISO 9001:2008 certified production; 100% dimensional & hardness inspection |
| Why Choose BDL Over Generic Brands? | Higher radial runout control (<0.015 mm), tighter raceway surface finish (Ra ≤0.2 μm), and extended service life (≥2× avg. competitor) |
Applications: Crane hooks, overhead hoists, marine winches, steel mill manipulators, and hydraulic press columns.
FAQ: Q: Are these drop-in replacements for SKF 51334? A: Yes — identical mounting dimensions and load ratings. Q: Can they operate at 120°C continuously? A: Yes — with high-temp grease (e.g., SKF LGHP 2). Q: Is custom OEM marking available? A: Yes — free laser engraving of your logo or part number.
