SYG-7080

SYG-7080

Synthetic High Performance Grease

 

Product Description

SYG-7080 is a high-performance grease which combines a synthesized ester base fluid with a lithium complex soap thickener. The thickener system provides a high dropping point, excellent resistance to water wash,and a tenacious structural stability. The unique physical properties of the synthetic base oil, combined with selected additives, provide outstanding protection against wear, rust, corrosion, and high-temperature degradation. The wax-free feature of the synthetic base oil allows for low-temperature mobility/pump ability and very low starting and running torque values. Also, the traction property of the synthetic base fluid is considerably lower than mineral oil, allowing for temperature reductions in the load zone of rolling element bearings.

 

Recommended Usage

SYG-7080 is recommended for aviation applications which need a lubricant that can perform normal functions yet go far beyond in terms of high and low temperature and long-life performance. It is an NLGI Grade 2 grease having the cold-temperature pumping resistance of most mineral-oil NLGI Grade 0 greases. It is a true wide-temperature, multi-service grease.

 

Proven Benefits:

·          Contains no lead or nickel.

·          High load carrying capacity.

·          Suitable for long-term lubrication.

·          Wide service temperature range (-45°C to 220°C; fo rshort periods up to +250°C).

·          Suitable for very high rotational speeds.
