High Temperature EP Grease (-20°C to 800°C) Supplier in India

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 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.

  • 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 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 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.
  • 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.
