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:
