Description of Calcium Grease
CALCIUM grease is an extreme pressure and high temperature grease. Calcium’s are high-performance general-purpose greases based on high-quality mineral base oil.
They contain anti-wear, anti-oxidation and anti-corrosion additives to enhance their performance in a wide range of applications.
It is a popular choice for various applications due to its affordability and good overall performance.
High resistance to water wash-out, appropriate anti-wear performance, friction reduction and good structural stability are among its various features and benefits.
It has an Operating temperature range between -20 to +60°C.
Application of Calcium Grease
-
Automotive
It is a staple for lubricating various parts in older vehicles, particularly for: - Chassis components: This includes components like ball joints, tie rod ends, and control arms that move and experience friction.
- Wheel bearings: It protects the bearings from wear and tear, ensuring smooth rolling of the wheels.
- Suspension components: Grease applied to suspension parts like leaf springs or shocks helps reduce friction and noise.
-
Industrial
Many industrial machines operating under moderate temperatures and loads benefit from it. Some examples include:
- Electric motors: The grease helps keep motor bearings lubricated for smooth operation and extended lifespan.
- Pumps: Calcium grease protects bearings and seals in pumps used for various fluids.
- Conveyor systems: Lubrication of bearings and rollers on conveyor belts ensures smooth operation and reduces wear.
-
Agriculture
Affordability and water resistance make it a popular choice for farm equipment like:
- Tractors: Grease protects various components like bearings in the drivetrain and axles.
- Harvesters: Calcium grease applied to harvester bearings and linkages minimizes friction and wear during operation.
- Trailers: Lubrication of wheel bearings and suspension components on trailers is crucial for safe and smooth operation.
While calcium grease offers these advantages, it’s important to consider its limitations
- Temperature Range: It’s not ideal for extremely hot or cold environments.
- Shear Stability: Under high friction conditions, the consistency might break down.
- Relubrication Frequency: Compared to some synthetic greases, calcium grease may require more frequent relubrication due to its consistency.
In conclusion, calcium grease is a versatile and cost-effective lubricant for various applications, particularly in presence of moisture and for moderate temperatures and loads.
