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.
