Polyurea grease is a special polyurea thickened grease with excellent high and low temperature lubrication performance, excellent bearing life and good waterproof and rust resistance. Polyurea grease is designed to meet the strict lubrication requirements of ordinary bearings and rolling bearings, including sealed life bearings, motor bearings, high temperature pump bearings, continuous casting machine bearings, etc.
Key Features & Benefits of Polyurea Grease:
Due to good stability and anti-aging ability, the time interval between grease filling is longer when used under long-term high load, avoiding oil change.
The special structure of polyurea grease also allows it to limit wear phenomena even at very low temperatures.
Polyurea grease reduces maintenance interventions, reduces noise disturbances and extends service life.
