Grease for Plain Bearings (Bushings)
Lubricant selection inputs for plain bearings/bushings, considering boundary lubrication and material compatibility.
This page lists neutral selection inputs. Confirm equipment manufacturer specifications before selecting a lubricant.
Operating Conditions
| Operating Parameter | Typical Range/Value |
|---|---|
| Motion | Oscillating or intermittent motion common |
| Load | Can be high; boundary lubrication regime possible |
| Material | Bronze, polymer, or composite bushing materials may have constraints |
| Contamination | Dust and water exposure varies by environment |
Required Lubricant Properties
| Required Property | Specification |
|---|---|
| Anti-wear Performance | Required where boundary lubrication occurs |
| Compatibility | Confirm with bushing material (e.g., polymer compatibility) |
| Viscosity/Consistency | Appropriate to speed and load; often NLGI 1–2 (verify) |
| Water Resistance | Required where washdown occurs |
