Uniflor™ 8922EL - Precision Bearing Grease
Automotive bearings in underhood applications such as those found in EGR Valves, e-turbo, and electronic throttles, are exposed to aggressive fuel vapors and a wide temperature range. Lubricants for these components must be able to withstand these harsh operating requirements while offering superior protection against wear and corrosion. The grease must also remain fluid at low temperatures and exhibit excellent low temperature torque properties.
Uniflor™ 8922EL is a high-performance low volatility precision bearing grease that provides extended performance across a wide temperature range and offers corrosion protection in chemically aggressive environments as well.
Uniflor™ 8922EL contains a high-performance additive package for enhanced wear and corrosion protection, providing greater protection and longer life than the legacy PFPE-based bearing greases.
Advantages
- Prevent corrosion
- Extend bearing life
- Reduce low temp torque
- Improve bearing efficiency
- Protection at high temperatures
- Protection from aggressive chemicals
Typical Properties
Uniflor™ 8922EL is a PFPE, PTFE-thickened grease with a wide operating temperature range. Base oil and grease properties are for reference only and are not to be used for the final design and specification of a lubricant.
Application Specific Tests
Nye’s application testing services can provide you with data to help qualify your design. BeQuiet testing of Uniflor™ 8922EL shows significantly lower noise readings compared to the Legacy PFPE grease (84.5%), indicating increased bearing life.
