SYG-462/ POLYTHERM GREASE
HIGH TEMPERATURE LUBRICATING GREASE
Product Description
SYG-462 POLYTHERM GREASE is high temperature lubricating greases based on mineral oil and polyuria. They have a wide service temperature range and can be applied in rolling bearings up to 180°C. If the lubricant is used in central lubrication systems, operating temperatures up to 200°C are possible. SYG-462 POLYTHERM GREASE feature highly effective anti-wear properties. The greases are very adhesive and resistant to water both under static and dynamic load. SYG-462 POLYTHERM GREASE is resistant to oxidation and provide reliable protection against corrosion.
Application
SYG-462 POLYTHERM GREASE is particularly suitable for applications in smelting works and rolling mills, especially for high-temperature lubrication points supplied through a central lubrication system, e.g. – drive rollers in continuous casting installations (slabs and billets) – conveyor rollers in continuous furnaces Lubricants for such applications must meet extremely high requirements regarding operating temperature, scaling, water and ensuing corrosion. SYG-462 POLYTHERM GREASE is also suitable for other high-temperature applications, such as:
·
Annealing furnaces, drying stoves
·
Plain bearings in foundry cranes hot rolls in cardboard
manufacturing plants
·
Road tarmacking machines
·
Shut-off gates in bulk material installations
· Cooling beds, conveyor systems rotary kilns – machines and installations in the automotive, beverage, glass and ceramics industries
