Key Specifications & Advantages of SKF-Grade Thrust Ball Bearing 51324M
| Description | Core Value |
|---|---|
| Model: 51324M (also compatible with 51320M/51322M/51324M series) | Universal interchangeability across major thrust bearing standards |
| Dimensions: 120×210×70 mm | Precise fit for heavy-duty mechanical transmission systems |
| Material: High-purity bearing steel (GCr15 equivalent) | Enhanced fatigue resistance & extended service life |
| Precision等级: P0 to P2 (ABEC-1 to ABEC-9) | Ultra-low runout for high-speed, low-vibration applications |
| Lubrication: Grease or oil-compatible | Flexible maintenance — ideal for sealed or circulating systems |
| Vibration grade: Z1V1 to Z3V3 | Meets ISO 10816 for critical rotating equipment |
| Non-aligning, separated, single-row thrust design | Optimized axial load capacity up to 285 kN (static) |
| Certified: ISO 9001:2008 | Consistent quality control — traceable batch documentation |
| Origin & Capacity: Made in China | 1M units/year | Reliable supply chain with OEM/ODM support |
| Applications: Gearboxes, cranes, hydraulic pumps, machine tools | Proven performance in industrial automation & construction machinery |
Why choose this SKF-aligned thrust bearing? Unlike generic imports, it features tighter raceway hardness tolerance (HRC 60–64), optimized ball groove geometry for 12% higher axial load rating, and laser-etched BDL branding for authenticity. All units undergo 100% dynamic testing before shipment.
FAQ: Q: Is preload adjustable? A: Yes — via matching washer selection. Q: Can it handle radial loads? A: No — strictly axial; use paired with radial bearings. Q: What’s the max speed (grease-lubed)? A: 1,800 rpm (with proper cooling). Ready to request a quote or sample? Contact us today — technical team responds within 2 business hours.
