Sliding bearings of the acceptance criteria
Bearings used to what extent can only be judged to be abandoned, different species have different criteria for judging, you need a concrete analysis of the structure of the bearings can be divided into the following :
1, sleeve,
1) sleeve inside diameter exceeding the prescribed maximum, ie, shaft diameter plus the maximum allowable bearing clearance;
2) stem diameter is less than the minimum required size, and knurled can not guarantee the quality requirements;
3) the bushings occur when burning or axle.
Second, the split bearing
1) severe wear of the bearing alloy, its thickness decreases more than 1/2;
2) the bearing alloy layer shelling, cracking is severe, an area of  more than 1/3;roller thrust bearings
3) bearing alloy layer is a serious burn;
4) bearing alloy with the axis of the contact angle of greater than 120o, can no longer shovel scraping mouth plane to adjust the contact angle or side gap is too large can not be adjusted.
Third, the thin wall tile
1) of the bearing alloy layer Shaorong;
2) the bearing alloy layer badly worn, the occurre nce of bites, and can not be padded to tighten;
3) when the shelling or cracking of the bearing alloy layer;
4) the bearing alloy layer of wear and tear is not too serious, but can not guarantee that the service intervals;buy bearing
5) bearing alloy layer wear, need padded law to tighten the bearing, gasket thickness more than 0.5mm.
Fourth, the thrust bearing
1) thrust pad of serious wear and tear, its thickness decreases to 1/2;bearings high speed
2) the thrust pad Shaorong;
3) The thrust pad shelling, cracking.
