Description
Sinopec Extreme Pressure Lithium Base Grease NLGI 1
Sinopec Extreme Pressure Lithium Base Grease NLGI 1 is an extreme pressure grease, formulated with a lithium soap thickener and high-quality mineral base oil. It contains rust and oxidation inhibitors, and extreme pressure and antiwear additives to ensure excellent performance and long life, even in severe service conditions where high temperatures, shock loading and water contamination are possible.
Features and benefits
- Excellent extreme pressure and antiwear properties protect heavily loaded or shock-loaded bearings from wear, extending equipment life.
- Lithium soap thickener ensures good mechanical stability, so the grease structure does not soften or break down in service.
- High-quality base oil ensures a good oil film thickness is maintained, even in high-temperature applications, protecting components from wear.
- Excellent protection against rust and corrosion ensures long component life, and extends maintenance intervals.
- Good thermal and oxidation stability ensure longer grease life under high-temperature conditions, providing optimum lubrication, extending equipment life and reducing maintenance requirements.
- Grease adheres strongly to metal surfaces, sealing out dirt and abrasive materials, to ensure longer lubricating intervals.
- Available in NLGI grades 00, 0, 1, 2 and 3 to meet the requirements of specific application.
Applications
Sinopec Extreme Pressure Lithium Base Grease NLGI 1 is suitable for use in:
- Bearings and gears of medium to heavily loaded mechanical equipment, where an extreme pressure/antiwear grease.
- Applications where the temperature range is from –20°C to 120°C.
