1. Product Descriptions
Rock bit grease with WS2 is composed of synthetic base oil, complex soaps, anti-wear and extreme pressure additives, antioxidant, anti-rust agent and other effective additives has high temperature resistance, long-life and excellent anti-wear property.
2. Features
l Excellent extreme pressure, anti-wear and anti-friction properties and a good heavy load capacity easily tolerate the heat generated at a lower level.
l Excellent high temperature oxidative stability assures lubricant pairs to work normally at high temperatures for a long time.
l Comprehensive protection of bearings to extends the bearings’ life. Excellent lubrication for the metal surface, especially in the boundary lubrication condition.

4. Applications
l The grease is used in the bearing under extremely high temperature and heavy load conditions, especially lifetime lubrication for seal or half-seal bearings.
l The grease has excellent usability for continuous lubricating and extended lubrication intervals, as fully synthetic grease can guarantee and extend the lifetime of the applied grease and bearings, gears, axle pin, slide rail and other parts.
l The grease is widely used in environments with high temperatures, heavy-load, moisture and conditions promoting rust such as mining, iron and steel industry, paper making and lumbering industry.
5. Notes
l Clean the lubricated parts and do plastic compatibility test before use.
l Store the products in a cool dry place, and avoid water and other debris which could affect product quality.
l Using temperature range: -20℃ ~ +250 ℃. 270℃ for a short time.
l Anti-seize applicable temperature range: -20℃ - +1000℃.
