lysn bearings for rolling mills

lysn cylindrical roller bearing of the motor temperature is too high or too much current ; three , the rotary motor and a hydraulic coupling or coupling keyway squeezed so bad and so on. After delamination occurs , must be promptly repaired. Otherwise delamination area will be expanded to the entire slewing scrapped. Repair method is: first slewing roller or ball inside out, so that separation of the inner and outer ring ; then gasoline to clean the raceways ; then grinder ( wheel ) carefully around the floor area will be incurred crack hardened layer rubbed off , the bottom layer will peel polished ; raceway need for welding and cutting torch used at the warm-up , with ( must dry before use electrodes and as lysn bearings for rolling mills baking ) carbon steel welding rod , to make the solder layer just above the raceway surface of 1-2mm; If the peel layer deeper or larger, should be layered sub- welding , not the base material caused by high temperature deformation
