Chesterton 635 SXC Synthetic, Extreme Pressure & Corrosion Resistant Grease
Categories: Fluid; Lubricant

Material Notes: Description: Chesterton® Synthetic Extreme Pressure & Corrosion Resistant Grease is the one grease to use for the most demanding lubricating needs. It is a multi-purpose workhorse with outstanding extreme pressure and anti-wear capabilities, shear stability, temperature and corrosion resistance. Superior resistance to washout by water, caustics, and acids, sanitizing cleaners, process fluids and steam has now been combined with high temperature performance to produce Chesterton 635 Synthetic Extreme Pressure & Corrosion Resistant Grease. As a premium quality, water resistant grease, 635 will not be removed even in severe water washout situations. Chesterton 635 can be used in steam and direct water contact services. Up to 50% water contamination will not diminish properties of Chesterton 635. With a dropping point of 318°C (604°F), it will not melt and run out even at high speeds or under heavy loads. 635 SXC has great ability to extend bearing life, reduce equipment repairs and improve operational efficiency of grease lubricated equipment. Uses for 635 SXC can be found throughout any industrial plant or process. It is especially advantageous where there is exposure to high humidity, corrosive vapors and shock loading or vibration as found in pulp and paper mills, mining operations, power generating plants, steel mills and metal forming operations. Applications include the lubrication of pinch roll and press roll bearings, oven conveyors bearings, cranes and mechanical presses.

Features:

  • Virtually impervious to water and steam
  • Synthetic Base Fluid
  • Compatible with most elastomers and seals.
  • Smooth, Buttery Texture
  • Adheres to Metal
  • Water and Corrosion Resistant
  • Wide application temperature range
  • Speed Rating, DN to 500,000.

Sugested Uses: Use in all applications where conventional greases break down under shear, thermal abuse, shock loading and water contamination. Chesterton 635 SXC can be used wherever thermally stable grease is required.

Applications:

  • Lubriation of slides, guides, plain bearings and bushings
  • Anti-friction bearings, roller bearings, and ball bearings
  • Grease-lubricated chains
  • Gears, cams, ball screw actuators
  • Motor Operated Valves, Limit Switch and stem Nut
  • Couplings, joints and splined shafts
  • Machine tool spindles

Lubricating Additives: Non Heavy Metal, Extreme Pressure and Anti-Wear, Anti-Fretting Additives, Surface Reactive Anti-Rust and Corrosion Additives, Oxidation Inhibitors
