High Temperature EP Grease With WS2

This high-performance grease is formulated with a high-viscosity synthetic base oil, Tungsten Disulfide (WS2) particles, and a blend of special performance-enhancing additives.

Key Features of High Temperature Grease

Key Properties of High Temperature Bearing Grease

High-speed machinery requires precisely engineered lubrication. The wrong grease can increase heat, friction, and even cause premature bearing failure. Selecting the appropriate high-temperature bearing grease is essential for maintaining performance, reliability, and longevity in demanding environments.

Speed Factor and Grease Selection

For machines with a speed factor (bearing bore × RPM) above 500,000, high-temperature bearing grease is recommended.
These greases are specially formulated to maintain lubricity and stability under extreme rotational speeds and heat.

Viscosity and Operating Conditions

Viscosity determines how thick or thin the grease’s lubrication film is.
It must be selected based on bearing load, rotational speed, and surface interaction.
As bearing speed increases, a lower viscosity is needed to minimize internal resistance and friction.
- However, at higher temperatures, grease viscosity naturally decreases—making thermal stability a critical factor for high-speed operations.

Channeling Behavior

Channeling refers to how easily grease moves and reforms within the bearing during rotation.
Good channeling properties reduce churning, which minimizes heat buildup and energy loss.
Proper channeling ensures the lubricant stays where it’s needed without being excessively displaced.

Thickener Type and Texture

The thickener acts like a sponge, holding and releasing oil as needed.
Short-fiber thickeners have a smoother texture and allow better channeling, making them ideal for high-speed applications.
In contrast, long-fiber thickeners may offer higher mechanical stability but can restrict channeling, leading to increased temperature and wear.
