Product Details
Key Specifications & Advantages of SKF-Grade Thrust Ball Bearings (51316, 51138–51148)
| Description | Core Value |
|---|---|
| High-Precision Grades (P0–P2) | Ensures ultra-low runout & extended service life in high-speed thrust applications |
| Grease/Oil Lubrication Compatible | Flexible maintenance—ideal for sealed or circulating systems |
| Non-Aligning, Separated Design | Easy assembly/disassembly; precise axial load control without misalignment risk |
| Bearing Steel (GCr15 Equivalent) | Superior hardness & fatigue resistance—meets ISO 9001:2008 manufacturing standards |
| Thrust-Only Load Direction | Optimized for pure axial loads—no radial capacity required, maximizing efficiency |
| Vibration Classes Z1V1–Z3V3 | Guaranteed quiet operation in precision machinery (e.g., machine tool spindles) |
| Compact 80×140×44 mm Size | Space-saving fit for hydraulic pumps, automotive transmissions & industrial clutches |
| OEM/ODM Support + In-Stock Availability | Fast lead times & custom branding—no project delays |
| HS Code 8482102000 | Made in China (BDL) | Export-ready compliance with global customs & traceable quality control |
| 1,000,000 pcs Annual Capacity | Scalable supply for distributors and large-volume integrators |
Why Choose These vs. Generic Thrust Bearings? Unlike standard alternatives, these feature tighter dimensional tolerances, certified vibration performance, and full separation—critical for repeatable OEM assembly. All units undergo 100% dynamic testing before dispatch.
FAQ: Q: Are these interchangeable with original SKF 51316? A: Yes—dimensionally and performance-identical; ideal for SKF-compatible retrofits. Q: Can they handle shock loads? A: Optimized for steady axial thrust; consult for intermittent high-impact use. Q: Is BDL equivalent to SKF material spec? A: Yes—GCr15 steel, hardened to 60–64 HRC, per ISO 683-17.
