Description
Sinopec Heavy Duty LC Mining Grease is a high temperature extreme pressure (EP) grease formulated with a lithium complex soap thickener and high viscosity mineral base oil, available in NLGI 2. It contains rust and oxidation inhibitors, EP and antiwear additives, as well as 5% of solids including molybdenum disulfide (MoS2 or ‘moly’), which provide additional wear protection especially under the severe vibrating or oscillating conditions that are found in many mining applications.
Appearance: "Normal" Grease
Consistency: Peanut Butter
Pack Size: 35LB Pail (17KG Volume), Grade: NLGI 2
Features and Benefits
Sinopec Heavy Duty LC Mining Grease is suitable for use in:
- Off-road equipment used in the mining industry, particularly to lubricate slow-moving plain and rolling element bearings under severe conditions of very high loads, shock loading and vibrating or oscillating conditions.
- 5th wheel applications where long life is needed.
- Heavy duty construction, earthmoving, mobile and stationary equipment, especially in those applications operating under very high loads, shock loading and vibrating or oscillating conditions.
- Some heavy duty applications that are difficult to access, and for which long lubrication intervals are required.
Features and Benefits
- Excellent extreme pressure and anti-wear properties protect heavily loaded or shock-loaded bearings and gears from wear, extending equipment life.
- Solids, including molybdenum disulfide, provide an additional measure of residual lubrication and protect metal surfaces against wear in applications where vibrating or oscillating movement tends to squeeze out the grease from between metal surfaces.
- Lithium complex soap thickener ensures a high dropping point, which means that the grease can be used at higher temperatures in severe service applications (operating temperature range is from –10°C to +150°C), and also confers excellent mechanical stability so that the grease structure does not break down in service.
- High base oil viscosity ensures a good oil film thickness is maintained even under severe high-temperature conditions, 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.
