Fully synthetic high temperature grease
Overview:
RheoLife 978N is a polyol ester based oil thickened by special dianisoylurea with high viscosity, high and low temperature properties and excellent oxidation stability. And contains antioxidant, anti-wear agent and anti-corrosive agent prepared by long-term high temperature grease. With excellent high temperature, oxygen Stability, corrosion resistance and long life. Especially suitable for high temperature, lifetime lubrication bearings and gears.
Features:
- Excellent high temperature performance: provides protection even at high operating temperatures and excellent oxidation stability, long term lubrication.
- Good low temperature performance: operating temperature as low as -30ºC, the performance is still good, low temperature start and operation torque is small.
- Excellent wear protection: with special friction coefficient improver and antiwear agent, the friction coefficient is very low, effectively prevent wear and provide lasting lubrication protection.
- Good mechanical stability: stable consistency in use, not easy to soften, reduce the risk of leakage.
Application:
- High temperature bearing
- Bearings and gears for power tools
- High temperature gear and slide rails
- Other bearings, moving parts and joints
