The effect of spiral groove structure on properties and silt-impurity excretion ability of water lubricated bearings lubrication is studied through comparison experiments on tribology properties of spiral groove and straight groove water lubricated rubber bearings. The results show that the tribological properties of spiral groove water lubricating rubber bearings are superior to the straight groove’s. The spiral groove water lubricating rubber bearings is easier to form elastic hydrodynamic lubrication, reduce friction and wear, have good capacity of silt and impurity discharge, and have very good effect on extending the service life and protecting the normal operation of the equipment.
