What items should be inspected for tapered bearings?
2, tapered roller bearings are not allowed to have an electric drill pattern, vibration patterns, yin and Yang face and polished traces, did not promise to emerge supporting construction and obvious measurement traces, did not agree to knock bumps and obvious color difference.3, the name of the whole machine did not promise to have oxide skin.
4, tapered roller bearing ring after the whole machine after pickling, there should be no scald, the name of cooperation should not be a pickling visible traces of burns, and no response angle detection.Tapered roller bearing appearance should be smooth, lubrication, no plants, no scratches, no rust and no obviously difference, promised to pressure injury, damage, deformation and defects such as trachoma vipassana.
1, the tapered roller bearing without cracks, sharp edges, plants and rust; on the road has not agreed to the raceway of machining trace; super fine traces in the outer ring, the steel ball surface should be symmetrical task differences, not to have scratches, bumps;
