Introduction
High-precision thrust bearing made of bearing steel, compliant with ISO9001:2008. Features P0–P2 precision ratings, Z1V1–Z3V3 vibration control, and non-aligning, separated design. Ready for OEM/ODM service with in-stock availability.Key Specifications & Why Engineers Choose This Thrust Ball Bearing
| Feature | Value & Advantage |
| Model & Precision | 51234M, P0–P2 precision grades — ultra-low axial runout for high-speed machinery |
| Load Capacity | High axial load support (up to 385 kN dynamic), ideal for vertical shafts & gearboxes |
| 170×240×55 mm — standard ISO fit, direct replacement for SKF 51234, FAG 51234-M | |
| Material & Hardness | GCR15 bearing steel, 60–64 HRC — fatigue-resistant, extended service life |
| Lubrication Flexibility | Grease or oil compatible — optimized for both sealed and circulating systems |
| Vibration Grade | Z1V1–Z3V3 certified — minimal noise & smooth operation in precision equipment |
| Quality Assurance | ISO 9001:2008 certified, 100% dimensional inspection, batch traceability |
| Differentiator vs. Generic Brands | Stricter raceway surface roughness (Ra ≤ 0.2 μm), tighter cage concentricity ±0.03 mm |
| Typical Applications | CNC machine tool spindles, hydraulic pumps, marine thrust blocks, wind turbine yaw systems |
| FAQ: Can it replace SKF 51234? | Yes — identical mounting dimensions, load ratings, and ABEC/ISO tolerance equivalence |
