Improper disassembly shaker bearing could cause damage inside the bearing. Possible contaminants may enter or re-install the bearing error. Therefore, dismantling the vibrating screen bearings must be very careful, the axis must have the appropriate support, otherwise it may harm the bearing forces demolished.
1.The external demolition
Removing interference fit of the outer ring, prior to the housing outer circumference of the extrusion screw with a few screws, tighten the screws on one side equally. Removing the side. These usually cover screw holes blind plugs, shaker tapered roller bearings and other separation-type bearings, set a few notches in the housing block on the shoulders, use the pad, with press disassemble, or tapping the demolition.
