Grease for Needle Bearings
Selection inputs for grease used with needle roller bearings, emphasizing correct base oil viscosity and anti-wear performance.
This page lists neutral selection inputs. Confirm equipment manufacturer specifications before selecting a lubricant.
Operating Conditions
| Operating Parameter | Typical Range/Value |
|---|---|
| Load | High contact stress common |
| Speed | Application-dependent; may be moderate to high |
| Relubrication | May be sealed or serviceable |
| Contamination | Seal quality affects dirt/water ingress |
Required Lubricant Properties
| Required Property | Specification |
|---|---|
| Base Oil Viscosity | Match speed/load; too thin risks wear, too thick increases drag |
| EP/AW Additives | Often required under high load |
| Mechanical Stability | Resist softening/shear |
| Water Resistance | Needed for outdoor or washdown |
