Not all the damage I bearing could be restored, consider repair or replacement of the bearing for the bearing of an injury, the causes and extent of damage must be evaluated to avoid or reduce re-injury. Bearing damage caused by many reasons, such as improper installation, dirt intrusion or water intrusion is a common cause of early bearing damage. Common causes of damage analysis and the corresponding INA Bearings INA bearing life can be extended preventive measures.
A. Improper operation of:
Installation, improper operation or demolition may cause the cage deformation or defect
Preventive measures: use the appropriate operating, installation and removal tool
B. Inadequate lubrication:
Lubrication is inadequate or inappropriate may result in components abrasions or serious bearing deformation
Preventive measures: improved lubrication system, and timing appropriate to supplement or replace the lubricant
C. Rust and corrosion:
Contact with water may cause the bearing components pitting and rust. Bearing corrosion damage at work may lead to spalling
Preventive measures: periodic inspection seal to ensure a good seal, the correct storage INA Bearing
D. Current:
INA bearings rotate power may lead to a groove or notch. The rest of the bearing, the electrical operating Improper grounding can cause minor burns
Preventive measures: through appropriate ground connection to reduce or avoid the current through the bearing components prior to welding the outside of the INA bearings
E. External material:
Wear particle contamination and debris intrusion may lead to the INA Bearing face wear, abrasions and depression
Preventive measures: Clear the intrusion of particles and debris, and replace the lubricant, check the sealing system
F. Eccentric:
Eccentricity, tilt, or too much load may lead to geometric stress concentration or surface spalling
Preventive measures: precision machining INA bearing and retaining shoulder
INA bearings and equipment preventive maintenance, operation and external parts change the dismantled bearings to suspend the search seized, the demand in order to distinguish the sub-INA Bearing parts to whether to re-use and record the use of the situation is better than bad.
Followed by special search seized INA Bearing raceway, raceway and joint surface conditions as well as the confrontation between the frame of the state of wear, such as whether the damage and abnormal situation is to look at rolling qualify for the running track of the pavement. Discriminant bearing the possibility of re-use to thinking about the level of the bearing damage, mechanical function, the primary operation of the premise, search inspection cycle back again choice.
Search seizure effect, if it is found that INA Bearing damage and abnormal situation, identification of the notice in accordance with the phenomenon of bearing damage, and to develop countermeasures. In addition, the search inspection results, if there is the following defects, the bearings can not be used again, needs to change to a new INA bearings.
