Grease for High-Speed Bearings
Selection inputs for high-speed rolling element bearings, focusing on base oil viscosity, thickener type, and oxidation stability.
This page lists neutral selection inputs. Confirm equipment manufacturer specifications before selecting a lubricant.
Operating Conditions
| Operating Parameter | Typical Range/Value |
|---|---|
| Speed | High DN/NDm values possible; heat generation increases |
| Temperature | Elevated operating temperatures possible |
| Relubrication | May require shorter intervals or automated lubrication |
| Sealing | Contamination control affects life significantly |
Required Lubricant Properties
| Required Property | Specification |
|---|---|
| Base Oil Viscosity | Appropriate for speed/temperature (often lower viscosity) |
| Oxidation Stability | High; resist hardening and sludge |
| Low Bleed / Mechanical Stability | Maintain consistency at speed |
| Noise/Vibration Behavior | Low-noise greases where required |
