How To Categorize Industrial Gear Oils?
Industrial gear oils have two types: industrial gear oil or industrial closed gear oil and industrial open gear oil. Industrial closed gear oil can be named with the following table.
Other related standards
CKB anti-oxidized anti-rust
Industrial gear oil
Highly refined mineral oil with antioxidant, anti-rust agents, suitable for light load gears.
CKC extreme pressure
Medium load industrial gear oil
Better erosion resistance than CKB, suitable for medium load gears.
CKD extreme pressure
Heavy load industrial gear oil
Better erosion resistance and thermal stability than CKC, suitable for heavy load gears under high temperature.
CKE worm gear
Worm gear oil
Highly refined mineral oil or synthetic hydrocarbon with oiliness agent, suitable for worm gears.
CKT synthetic hydrocarbon extreme pressure
Low temperature medium load industrial gear oil
Have similar functions as CKC, but with good low and high temperature performance.
CKT synthetic hydrocarbon
synthetic hydrocarbon gear oil
Suitable for environment with great temperature change or chemical erosions, or other special purposes.
Industrial gear oil can also be grouped according to its viscosity at 40°C. the medium viscosity value is used as the name, viscosity value varies within ±10%.
