MX33 Rocol

MX33 is an extreme low temperature silicone grease containing molybdenum disulphide for enhanced load and wear performance, developed for use on highly loaded components operating in extremely low temperatures (as low as -73ºC). Highly resistant to water washout, it guarantees excellent EP performance with a weld load of 280kg. It’s particularly suitable for highly loaded applications, where shock and vibration can be present. Highly resistant to oxidation, MX33 provides long-lasting protection and extended lubrication intervals, reducing equipment failure, downtime and lubricant usage. The product does not affect most rubbers and plastics, but is incompatible with silicone rubbers.

Application: Effective lubrication and protection of all types of ball, roller and plain bearings, slide guides and pins, particularly those exposed to extremely low temperatures, e.g. in the automotive, aerospace and military industries.
