Not all damage the angular contact ball bearing can be fixed, but for every damage before considering repair or replacement of the bearing SKF bearings, must assess the cause and extent of the damage once again, in order to avoid or reduce injury. Bearing damage caused by many reasons, such as improper installation, intrusion of dirt or moisture intrusion is that many common reasons for early damage of the bearings. Common failure analysis of angular contact ball bearings and can extend the preventive measure of angular contact ball bearing life.
A． Improper operation:
Cage of improper installation, operation or removal may cause deformation or defect
Precautions: use appropriate operations, installation and removal tool
B． Insufficient lubrication:
Insufficient lubrication or incorrectly, you may cause the component abrasion or severe deformation of FAG bearings
Preventive measures: improvement of the lubrication system, timed properly to supplement or replace lubricants
C． Rust and corrosion:
Contact with water may cause the NSK bearings component corrosion and rust. Corroded bearings after injury while at work may cause spalling
Precautions: periodically check the seal ensures good sealing effect, the correct storage of angular contact ball bearings
D． Current:
Angular contact ball bearings rotating power on may cause a notch or nicks. TIMKEN bearings is stationary, electrical grounding improper operation will result in a slight burn
Precautions: outside diagonally-contact ball bearings in the parts before welding by appropriate ground connection to reduce or avoid the current through the bearing
E． External material:
Abrasive particle contamination and debris penetrated may cause the face of angular contact ball bearing wear, scratches and depression
Precautions: clear the intrusive particles and debris, replace lubricant, check the sealing system
F． Eccentricity:
Eccentric, inclined or geometric stress concentration, or excessive loads may cause surface spalling
Precautions: accurate processing of angular contact ball bearing seats and abutments
Diagonally-contact ball bearing equipment preventive maintenance, operation and external part is removed when you change the INA bearings suspension when soujian, demands in turn, distinguishing components of angular contact ball bearing can be used again and record the use of good to bad.
Second soujian Raceway of angular contact ball bearings, rolling surfaces and wear conditions of the joint venture and the confrontation without damage and abnormal conditions, such as special is to look at the Raceway surface running track. Distinguished bearing will once again apply, to thinking that KOYO bearings damage level, mechanical functions, primacy, premise, soujian cycle operation, such as another choice in the future.
Soujian effect, if it is found that damage and angular contact ball bearings have an exceptional condition, please follow the bearing damage identification announcements, develop policy responses. In addition, the soujian effect, if there are several flaws, the bearing can no longer be used, demand was replaced by a new angular contact ball bearings.
