Damage detection of bearing technology

1. clearance. For beyond delineation of tour gap grade range of bearing, or tour gap value has near ceiling, by polished or grinding Hou, tour gap very has may super poor, as C0 level bearing, tour gap super poor to C3 level, or has near C0 level ceiling, first will in analysis lecture in the informed customer, the set bearing has to C0 tour gap range ceiling outer ring roll road debris pressure marks outer ring roll road microseismic friction erosion (rubbed clothing Board shaped au slot) within ring roll road stick attached wear move body roll road stick attached wear outer ring outside round friction erosion within ring roll road serious tired peeling or super poor, Wedding customer premise bearing applications verify that C3 clearance can be used.
2. Diameter, width, ovality, wall thickness difference. Solutions factory repair for all brands of bearings, but scales the same quality of repair to bearing quality, size or precision bearings for the variance, scrap or replace the appropriate parts. For tapered roller bearings, you also need to measure the assembled high.
3. Poor move group. Bearing rings and arrive to move the detached or suspected was pinned into the different brands of body, need to move groups of scattered measured difference, to ensure that the move of self as a set, not mixed.
4. Ultrasonic flaw detection. Bearing after running for some time, under the bearing surface (depth within the 0.1~0.5mm) formed the microscopic cracks that cannot be observed with the naked eye, using ultrasonic to detect the bearing surface micro-crack-free, to determine if bearings have a fix value of reference.
5. The hardness. Tempering colors bearing surface hardness testing.
