OKS 420 is a mineral oil-based, polyurea-thickened, high-temperature grease for universal use. It is ideal for corrosive operating conditions at high operating temperatures and under high pressure and impulse loads. It can be used for the lubrication of heavily loaded gearboxes at relatively low speeds, for drives under high pressure and impulsive stress, lubrication of chains in the presence of water and steam and high operating temperatures. Operating temperature range: -10°C - 160°C. Drop point: > 230°C.
