Product Information
Description
Sinopec HP-R Grease is an extreme pressure, heavy-duty wheel bearing and chassis grease, formulated with a lithium complex soap thickener and high quality mineral base oil. It contains rust and oxidation inhibitors, EP and antiwear additives to ensure excellent performance and long life, even in severe service conditions such as high temperatures, shock loading and where water contamination is possible.
Features and Benefits
Sinopec HP-R Grease is suitable for use in:
- Automotive wheel bearings, particularly those operating under the high-temperature, high-load conditions that are caused by braking at high speed.
- General lubrication of chassis points (e.g. shackles, tie rod ends, steering knuckles, control arms and king pins), electric motors and water pumps of passengers cars, buses and trucks.
Features and Benefits
- Excellent extreme pressure and antiwear properties protect heavily loaded or shock-loaded bearings from wear, extending equipment life.
- Lithium complex soap thickener ensures a high dropping point, which means that the grease can be used at higher temperatures in severe service applications, and also confers excellent mechanical stability so that the grease structure does not break down in service.
- High-quality base oil ensures a good oil film thickness is maintained, even in high-temperature applications, protecting components against wear.
- Excellent water resistance means that the grease stays in place and is not washed or sprayed off in wet conditions, reducing the need for frequent re-application.
- Excellent protection against rusting 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.
- Suitable consistency meets the requirements of wheel bearing application, and avoids the grease being flung out of the bearing by centrifugal forces, so ensuring longer relubrication intervals.
