Product Description
High performance Castrol Tribol GR 4541 HT (previously called Tribol 4541) Wide Temperature Range Grease is a wide temperature lubricant designed to extend the service life of bearings when loads are moderate to heavy, temperatures are elevated, and speeds are low to moderate. This grease matches the rugged service requirements associated with mills and plants producing engineered woods, primary metals, castings, cement, glass, and paper.
The following performance characteristics were emphasized in the development of Tribol GR 4541 HT:
- Synthetic base fluid for high-temperature stability and low-temperature mobility;
- Optimum viscosity base oil, ISO VG 150, to increase the load carrying capacity;
- Temperature stability to withstand elevated and intermittently high temperatures (dropping point over 260 °C/500 °F)
- Shear stability to match the anticipated service life of precision anti-friction bearings.
Application:
Tribol GR 4541 HT should be used when loads are moderate to heavy, temperatures are elevated (up to 232 °C/450 °F),and speeds are slow to moderate.
Tribol GR 4541 HT can be used in anti-friction bearings, bushings, and couplings. In addition, the combination of synthetic base fluids provides outstanding low temperature grease mobility. Establish reapplication intervals by inspection. See Notes regarding temperatures and speeds. Primary Metals including Steel - Use Tribol GR 4541 HT near hot ingots, soaking pits, and reheat furnaces to lubricate pit cover carriages, mill stand screws, slipper couplings, roll bearings, manipulators and guide rolls for continuous casters. Use Tribol GR 4541 HT to lubricate bearings that are exposed to both low and high temperatures. These applications include conveyors exposed to both low winter temperatures and the high temperatures associated with foundry and casting operations. Paper and Forest Products €“ Use in areas exposed to high temperatures and/or outside winter temperatures.
