Description
Key Specifications & Advantages of BDL Thrust Ball Bearings (51230–51236)
| Description | Core Value |
|---|---|
| High-Precision Grades (P0–P2) | Ultra-tight tolerances for minimal axial runout—ideal for precision machine tools & CNC spindles |
| Grease/Oil Lubrication Ready | Flexible maintenance: pre-greased for quick install or oil-lubricated for high-speed, high-temp operation |
| Vibration Levels Z1V1–Z3V3 | Low-noise, smooth rotation—critical for medical devices and quiet industrial gearboxes |
| ISO9001:2008 Certified | Rigorous QC at every stage—traceable batches, 100% dimensional inspection |
| Non-Aligning, Separated Design | Easy assembly/disassembly; precise axial load control without misalignment risk |
| Bearing Steel (GCr15 Equivalent) | Hardened to 60–64 HRC; superior fatigue resistance vs. standard carbon steel |
| Single-Row Thrust Configuration | Optimized for pure axial loads—higher static/dynamic capacity than tapered alternatives |
| 150×215×50 mm Standard Size | Direct replacement for SKF 51230–51236—no re-engineering needed |
| OEM/ODM Support & In-Stock Availability | Fast lead time (24–48 hrs); custom branding, packaging, and spec adjustments |
| Made in China, HS Code 8482102000 | Compliant with global import regulations; full documentation provided |
Applications: Hydraulic pumps, vertical motor shafts, crane turntables, plastic injection molds, wind turbine pitch systems.
Why BDL over generic brands? Higher hardness uniformity, tighter raceway roundness (<0.005 mm), and batch-tested dynamic load ratings—verified per ISO 76.
FAQ: Q: Are these interchangeable with SKF? A: Yes—identical dimensions, load ratings, and mounting interfaces. Q: What’s the max speed? A: Up to 2,200 rpm (grease) / 3,000 rpm (oil), depending on cooling. Q: Do you supply test reports? A: Yes—load, hardness, and vibration certificates included per order.
