Hammermill Maintenance CPM

Hammermill bearings require good maintenance in order to provide long term trouble free service and lubrication is the key Unless a bearing has a leaking seal hammermill bearings do not require frequent lubrication In many cases the grease fittings are removed from hammermill bearings to prevent over lubrication If the bearing is too full of

14 Types of Bearings The Characteristics Differences and

A method for adjusting the blade clearance in a disc chipper by moving in the axial direction a bearing bushing of a disc shaft together with the bearing The axial movement of the shaft is effected by loosening adjusting screws or adjusting nuts of one of the end caps of the axial guide bearing housing and by tightening after this the adjusting screws or adjusting nuts of the other

Radial Internal Clearance Bearing Works

Radial clearance is the play between the ball and raceway perpendicular to the bearing axis Axial clearance is the play parallel to the bearing axis and is typically at least 10 times greater than the radial clearance Generally internal radial clearance will be reduced 80% of the interference fit amount Too little or too much internal clearance will significantly influence factors such as
