STREX - 455
STREX - 455
SYNTHETIC GREASE
PRODUCT
DESCRIPTION:
STREX-455 is high performance, extreme-pressure greases which combine a synthetic 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 selective 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
in these greases is considerably lower than mineral oil, allowing for
temperature reductions in the load zone of rolling element bearings.
Features and Benefits
STREX-455 synthetic grease
provides the following advantages when compared with mineral oil grease
intended for similar service. Operating range of -40˚ C to +240˚ C Excellent
resistance to rust, corrosion and oxidation Outstanding structural stability in
the presence of water. Excellent wear protection under heavy loads and high
temperatures
Power saving capabilities. Extended
re-lubrication intervals .Low volatility
Applications
STREX-455/220 is recommended for
industrial 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 NLGI Grade 2 grease having the cold temperatures pumping
resistance of most NLGI Grade 0 greases. It is a true wide temperature, multi
service grease.
STREX-455/460 an NLGI Grade I ½ grease is recommended for industrial application at both high and low temperatures. It will provide outstanding bearing protection under heavy loads at low to moderately high speeds, and where water is a factor. STREX-455/460 has performed extremely well in steel mill and paper mill applications. It also has proven exceptional service automotive chassis grease.
