Features & Benefits
Dual lip sealing structure prevents gear oil leakage and blocks dust, mud and water from entering the reducer gearbox.
Built-in garter spring maintains stable radial compression force on sealing lip under continuous heavy rotation and strong vibration of mixer reducer.
NBR nitrile rubber delivers reliable oil resistance and wear resistance for reducer gear oil operating environment.
Reinforced metal casing ensures firm press-fit installation and stable service life under heavy-duty working conditions.
This seal is an aftermarket replacement part; verify shaft and bore dimensions and concrete mixer reducer model before placing your order.
