Description:

ROCOL® MX550 is a high temperature silicone grease containing molybdenum disulphide for improved load carrying performance.

ROCOL MX550 is formulated from a highly stable silicone fluid which exhibits an exceptionally high resistance to oxidation for extended life particularly when it is subjected to high temperatures for prolonged periods. ROCOL MX550 is also extremely tolerant where temperatures fluctuate between high and low during use.

The addition of molybdenum disulphide in the ROCOL MX550 provides excellent lubricating properties and ensures maximum wear protection over extended periods. 

Features & Benefits:

• Excellent extreme temperature resistance ranging from -45°C to +280°C.
• Due to the inclusion of molybdenum disulphide ROCOL MX550 has very good load carrying and anti-wear performance.
• ROCOL MX550 is highly resistant to oxidation demonstrating long life and exceptional stability even in the most aggressive conditions.
• ROCOL MX550 has very good chemical resistance. 

Applications:

• ROCOL MX550 is specially developed for the lubrication of steam turbine valve gear, pedestal bearings and sliding feet operating at high temperatures.
• ROCOL MX550’s function is to allow for thermal expansion, permitting the turbine shell to easily slide and follow the turbine rotor as the turbine assembly expands and contracts. With steam temperature exceeding +500°C, this expansion can be quite excessive both axially and radially.
• ROCOL MX550 is officially recommended by GEC Turbines Ltd.
