Bearing Maintenance, Overhaul And Selection

Bearing is an important part of modern mechanical equipment.Its main function is to support the mechanical rotating body, reduce the friction coefficient in the process of movement, and ensure the accuracy of rotation.Below, BMB Bearings brings the knowledge of bearings to you.
1. Bearing maintenance
In order to maintain the original performance of bearings in good condition for as long as possible, it is necessary to maintain and overhaul to prevent accidents before they happen, ensure the reliability of operation and improve productivity and economy.The maintenance should be carried out regularly according to the operating standards of the mechanical operating conditions.The contents include monitoring the operation status, replenishment or replacement of lubricants, and inspection of regular disassembly.
2. Maintenance of bearings
Bearing cleaning: when dismounting the bearing for maintenance, first record the appearance of the bearing, confirm the residual slip agent, sample the lubricant used for inspection, and then wash the bearing.As a cleaning agent, the common use of cleaning agent, kerosene.The cleaning of the removed bearing is divided into coarse cleaning and fine cleaning, and placed in the container respectively. The metal net bottom is put first so that the bearing does not directly contact the dirt of the container.When rough cleaning, if the bearing rotates with dirt, it will damage the rolling surface of the bearing, and attention should be paid to it.In the crude cleaning oil, use a brush to remove grease and adhesions, roughly clean, into the fine washing.Fine cleaning is to clean the bearing carefully while rotating in the cleaning oil.In addition, the cleaning oil should also be kept clean.Bearing maintenance and judgment: in order to judge whether the removed bearing can be used, it should be inspected after the bearing is cleaned.Check the state of raceway surface, rolling surface and mating surface, wear of cage, increase of bearing clearance and damage and abnormality that have no relation to dimensional accuracy decline.

3. Selection of bearings
The market requirements for the performance of various mechanical devices and instruments using rolling bearings are increasingly strict, and the conditions and performance required for bearings are increasingly diversified.In order to choose the most suitable bearing from a large number of structures and sizes, it is necessary to study it from various angles.When choosing bearings, bearing arrangement, installation and disassembly difficulty, allowable space, size and marketability of bearings as shafting are generally considered, which roughly determine the bearing structure.According to different uses, it is necessary to choose bearings with special designs for accuracy, clearance, cage structure, grease and so on.However, there is no certain order and rules in the selection of bearings. What should be considered first is the conditions, performance and most related matters required by bearings, especially practical.
