Damage, assembly, maintenance and repair of NSK imported bearings
Not all damaged NSK bearings can be repaired, but for each damaged bearing, the cause and extent of damage must be evaluated to avoid or reduce re-damage before considering repairing or replacing a new bearing. There are many causes of bearing damage, such as improper installation, dirt intrusion or moisture intrusion, which are common causes of early damage in many bearings. Analysis of common causes of damage to NSK bearings and corresponding precautions to extend bearing life.
A. Improper operation:
Improper installation, operation or disassembly may cause deformation or defect of the cage
Precautions: Use appropriate handling, installation and removal tools
B. Insufficient lubrication:
Insufficient or improper lubrication may result in component scratches or severe bearing deformation
Precautions: Improve the lubrication system and properly replenish or replace the lubricant at regular intervals
C. Rusty and corrosion:
Contact with water can cause the bearing components to erode and rust. Bearings after rust damage may cause spalling during work
Precautions: Regularly check the seal to ensure a good sealing effect and properly store the bearing
D. Current:
Powering up the bearing as it rotates may result in grooves or nicks. Improper electrical grounding can cause minor burns when the bearing is stationary
Precautions: Reduce or avoid current flow through the bearings by properly grounding connections before soldering components other than bearings
E. External materials:
Wear particle contamination and debris intrusion may cause wear, abrasion and dents on the bearing face
Precautions: Remove invading particles and debris, replace lubricant, check sealing system
F. eccentric:
Eccentricity, tilting, or excessive loading can cause geometric stress concentrations or surface spalling
Precautions: Precisely machined housings and shoulders
When the NSK imported bearing equipment is regularly inspected and operated, and the bearings that have been removed during the replacement of the peripheral parts are stopped, it is necessary to determine whether the secondary bearing parts can be reused and the operation status is better or worse.
Secondly, check the raceway surface of the bearing, the condition of the rolling surface and the joint surface, and the damage and abnormal conditions of the truss wear. It is necessary to check the running track of the raceway surface. To determine whether the bearing can be used again, it is necessary to consider the level of bearing damage, mechanical function, primacy, operational premise, and inspection cycle.
If the bearing is found to be damaged or abnormal, please find out the cause according to the phenomenon of bearing damage and formulate countermeasures. In addition, the inspection effect, if there are the following defects, the bearing can no longer be used, the need to change the new bearing.https://www.supplyforever.com/
