Bearing maintenance method

Domestic is commonly used for rolling axis wear repair welding, changing method such as ball, pitting, but when the shaft is made of 45 # steel, quenched and tempered treatment, if only by surfacing welding processing, can produce welding stress, in the case of heavy load and high speed, can appear the phenomenon of crack and fracture at shoulder, if use the stress relieving, is difficult to operate, and the processing cycle is long, the high cost of maintenance; When the material of the shaft is HT200, it is not ideal to use iron welding. 

Some enterprises with high maintenance technology will adopt brush plating, laser welding, micro-arc welding and even cold welding. These maintenance technologies often require high requirements and high costs.
