Bearing installation should be preceded with gasoline or kerosene

taper roller 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 .

angular contact ball 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.

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 .
