casting unworked surface must Ex residual sand .

Bearing must be installed in a dry, clean environment conditions. Should be carefully checked before installation of shaft and housing mating surface , convex shoulder face , grooves and connecting surface processing quality. All fit connection surface must be carefully cleaned and remove burrs, casting unworked surface must Ex residual sand .

tapered bearing installation should be preceded with gasoline or kerosene to clean and dry before use, and to ensure good lubrication, bearings generally use grease, oil lubrication can be . Lubricated with grease should be used free of impurities , oxidation , rust and extreme pressure properties of high-quality grease. Grease filling is bearing and tank volume of 30% -60% , not too much . With sealing structure of the double row tapered roller bearings and water pump bearing grease has been populated , the user can directly use, can no longer be cleaned.

Slewing bearing installation must be on the circumference of the ring face exert equal pressure , push the ferrule may not be a direct hit with a hammer prime tool bearing face , so as not to damage the bearings . In the case of a small amount of interference , it can be pressed at room temperature with sleeve bearing ring face , beating with a hammer sleeve , the sleeve will be pressed into the ring balanced . If large quantities of installation , can be used hydraulic press . Press-fitting , should ensure that outer end face and the housing shoulder , inner end face and the shaft shoulder pressed , does not allow a gap .
