NTN Bearing hair ring 27 kinds of factors'

   Kunshan Bearings: After a long summary of technical personnel, NTN Bearing hair ring has the following 27 kinds of reasons, there may be a lot that we have not encountered, the future will slowly after the meeting.
1. NTN Bearing soot mixed with sand or other impurities, played the role of abrasives
2. NTN Bearing mixed with water, acids and other dirt or paint, play corrosive effect;
3. NTN bearing clearance is too small (with the selected inappropriately);
4 varieties of oil or grease choose the wrong;;
5 insufficient lubrication (oil level is too low, oil or grease leakage through the seal);
6. NTN bearings are bore clamp flat (bad housing bore roundness or bore distortion is not straight);
7. NTN bearing bottom horn uneven (deformed or even cause bore NTN bearing cracks);
8. NTN bearing manufacturer hole with debris (residual chips, dust, etc.);
9 ring eccentric (and adjacent parts encounter friction);
10.NTN bearings subject to additional load (NTN Bearing by axial limp tight, or a shaft has two fixed ends NTN bearings);
11 thermal elongation axis is too large (NTN Bearing be statically indeterminate additional axial load);
12.NTN bearing clearance is too small, too tight rotation (tight sets tighten too overdone);
13.NTN bearing noise (end or roller ball skidding caused);
14.NTN bearing and shaft with too loose (shaft diameter is too small or tight sets not tighten);
15 shaft shoulder too (NTN Bearing seals encountered and friction);
16 bore shoulder block too (the NTN Bearing seals hair badly distorted);
17 labyrinth seal gap is too small (and the shaft friction);
18 lock washer tooth bending (NTN bearings and friction encountered);
19 dumped oil ring inappropriate location (across the flange cover and friction);
20. Ball or roller pressure on the pit (installed with a hammer NTN bearings caused);
21.NTN bearing noise (with external local oscillator interference);
22.NTN bearing heat discoloration and deformation (NTN bearings using the gun heating caused by demolition);
23 is too thick so that the actual shaft with tight (caused by NTN Bearing temperature or the occurrence of noise);
24.NTN bearing noise (NTN bearings with micro abrasion).
25.NTN bearing hole diameter is too large, the actual fit is too loose (NTN Bearing temperature - outer slip);
26.NTN bearing hole becomes larger (non-ferrous metals NTN bearing hole is stretch, due to thermal expansion or larger);
27 bore diameter smaller (NTN Bearing temperature causes).
