Key Specifications & Why Engineers Choose This Thrust Ball Bearing
| Description | Core Value |
|---|---|
| Model: 51234M (ISO Standard) | Precision thrust bearing with optimized load distribution for axial-only applications |
| Dimensions: 170×240×55 mm | Direct replacement for SKF 51234, FAG 51234 — seamless integration in existing systems |
| Precision Grades: P0/P6/P5/P4/P2 | Ultra-precise rotation control — ideal for CNC spindles and high-speed machinery |
| Lubrication: Grease or Oil Compatible | Flexible maintenance — reduces downtime and extends service life |
| Vibration Levels: Z1V1 to Z3V3 | Low-noise operation — critical for medical devices and precision instruments |
| Material: High-Carbon Chromium Bearing Steel | Superior hardness & fatigue resistance — 30% longer L10 life vs. standard grade |
| Certified: ISO 9001:2008 | Consistent quality — traceable batch testing & full QC documentation provided |
| Non-Aligning, Single-Row, Separated Design | Easy installation & maintenance — no misalignment risk during assembly |
| Origin: China (BDL Brand) | Factory-direct pricing — 40% lower than premium imports, zero compromise on core specs |
| Stock Status: In Stock | Same-day dispatch — no project delays due to lead time uncertainty |
Used in hydraulic pumps, gearboxes, machine tool spindles, and aerospace actuators where pure axial loads dominate. Unlike generic thrust bearings, this model features tighter raceway geometry tolerances and superior surface finish (Ra ≤ 0.2 μm), reducing heat generation by up to 22%. Backed by 100% dimensional inspection and dynamic load validation per ISO 76. FAQ: Q: Is preload adjustable? A: Yes — separable design allows precise preload tuning. Q: Can it handle shock loads? A: Rated for intermittent shock up to 1.5× static load (per ISO 281). Q: What’s the max speed? A: Up to 2,800 rpm (grease-lubricated, light load).
