| Parameter Item | Precise Technical Specification |
|---|---|
| Base Material | Oil‑groove bearing grade 42CrMo steel, surface quenched HRC 56‑60, high thermal stability under continuous heavy rotation |
| Groove Profile | Optimized combined spiral‑axial oil groove, 97.5% lubricant coverage, enhances oil flow and dissipates frictional heat |
| Dimensional Tolerance | ID / OD tolerance ±0.004 mm, engineered for interference and transition fit assembly |
| Load & Service Life | Max dynamic load 340 MPa; service life 2.4× longer than standard non‑grooved steel bushings |
| B‑End Purchaser Type | Local Industry Pain Points | Quantitative Product Advantages |
|---|---|---|
| Mining Machinery Component OEMs | Mine site high‑dust, heavy‑rotation conditions; poor oil circulation creates thermal seizure; 14‑19% of unit breakdowns stem from bushing overheating; high field‑replacement labour cost | Our Steel Bushing Oil Groove improves lubricant circulation and heat dissipation. This Steel Oil Groove Bushing cuts thermal‑seizure failures by 76%, lowers on‑site replacement frequency by 58%, and reduces field maintenance expenses by 23%. As rugged Industrial Bushings, it maintains stable performance under abrasive mining‑site working conditions. |
