Grease for Slow-Speed Open Bearings
Selection inputs for grease used on slow-speed, open bearings where contamination control and film thickness matter more than low drag.
This page lists neutral selection inputs. Confirm equipment manufacturer specifications before selecting a lubricant.
Operating Conditions
| Operating Parameter | Typical Range/Value |
|---|---|
| Speed | Low speed; boundary/mixed lubrication common |
| Sealing | Open bearing—exposed to dirt/water |
| Relubrication | Periodic regreasing expected |
Required Lubricant Properties
| Required Property | Specification |
|---|---|
| Adhesion/Stay-Put | Resist fling-off at low speed |
| Water Resistance | Needed for outdoor exposure |
| Contamination Tolerance | Prefer robust thickener and EP/AW package |
| Corrosion Protection | Prevent rust on exposed races |
