What is High Temperature EP Grease with Tungsten Disulfide (WS2)?

Jade Chemicals is a specialised High Temperature EP Grease supplier in India, offering a synthetic-based lubricant fortified with Tungsten Disulfide (WS2). This advanced grease provides an exceptional dropping point above 320°C and maintains structural integrity from -20°C to 800°C to prevent bearing failure in extreme thermal and load-bearing environments.

Key Features of High-Performance Industrial Grease

  • Exceptional Thermal and Oxidative Stability: This high-performance grease is formulated with a synthetic base oil that offers a dropping point above 320°C. This ensures that the lubricant does not liquefy or bleed out of the bearings during peak thermal cycles in industrial kilns or furnaces.
  • Extended Operating Temperature Spectrum: Our grease is engineered to maintain a consistent lubricating film across a wide range of temperatures from -20°C to 800°C. It provides a reliable safety margin for high-speed machinery that experiences rapid temperature fluctuations during continuous operation.
  • Advanced WS2 Load-Bearing Capability: The inclusion of Tungsten Disulfide (WS2) particles enhances the Extreme Pressure (EP) properties of the grease significantly. This solid lubricant additive prevents metal-to-metal contact and surface welding even under massive mechanical loads that would cause standard greases to shear.
  • Mechanical Stability and Long-Term Longevity: The specialised thickener system delivers outstanding mechanical stability and resistance to water washout or chemical degradation. It effectively extends service intervals and protects high-speed bearings from premature wear, rust, and corrosion in harsh industrial 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.

FAQs

As a trusted High-Temperature EP Grease in India (-20°C to 800°C) supplier in India, Jade Chemicals formulates advanced grease using Tungsten Disulfide (WS2) due to its extremely low friction coefficient (0.03) and high thermal stability up to 800°C. Unlike conventional additives such as MoS₂ or graphite, WS2 continues to provide dry lubrication protection even when the base oil begins to degrade under extreme heat conditions.

High-Temperature EP Grease in India (-20°C to 800°C) supplier in India products are engineered with a high dropping point of around 320°C, ensuring the grease maintains its semi-solid structure under heat. This prevents leakage from bearing housings, reduces lubricant starvation, and helps avoid premature bearing failure in high-temperature applications such as conveyors, furnaces, and exhaust systems.

As a leading High-Temperature EP Grease in India (-20°C to 800°C) supplier in India, Jade Chemicals offers customized NLGI grades to suit different lubrication systems. NLGI 1 grades are available for improved pumpability in centralized systems, while NLGI 2 grades provide better retention in vertical shafts and heavy-load applications, ensuring optimal performance and lubrication efficiency.

High-Temperature EP Grease in India (-20°C to 800°C) supplier in India formulations based on synthetic WS2 technology offer excellent stability, but a full system purge is recommended before changeover. Mixing different grease chemistries may cause thickener incompatibility, leading to softening or leakage. A clean system ensures maximum performance and full high-temperature protection up to 800°C.
