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
