| Parameter Item | Precise Technical Data |
|---|---|
| Base Material | Alloy 20CrMn steel, carburized surface hardness HRC 58‑62, high impact resistance |
| Groove Machining | Multi‑directional intersecting oil groove, 96% lubricant spread coverage, no localized dry friction spots |
| Dimensional Accuracy | Inner/outer diameter tolerance ±0.004 mm, matched for press‑fit assembly requirements |
| Performance Rating | Max static load 320 MPa; service life 2.2× versus standard non‑groove steel sleeves |
| B‑End Purchaser Type | Local Industry Pain Points | Product Quantitative Advantages |
|---|---|---|
| Agricultural Machinery OEM Manufacturers | Outdoor dirty working environment; dust contaminates lubricant; plain sleeves wear rapidly; 12‑17% of field breakdowns link to bushing damage; frequent on‑site part swap raises after‑sales service spending | This Steel Bushing with Groove traps residual grease against dust intrusion. It supports continuous cyclic loading in farm equipment. Field testing shows 55% fewer bushing replacements, 16% drop in field breakdown rate, and 24% reduction in after‑sales service costs. As robust Industrial Bushings, it fits harsh outdoor agricultural operating conditions. |
