Rolling bearings have higher precision than general mechanical parts, so care should be taken when using them.
1) Keep the bearings and their surroundings clean
2) Careful and careful when using
If it is used carelessly to give the bearing a strong impact, the bearing will be injured, indented, broken and injured.
3) Use the right tools
4) Pay attention to the rust prevention of the bearing
Avoid using it in wet areas, and wear gloves if you don't get sweat on it.
5) Users should be familiar with bearings
6) Develop operating specifications for bearing use
a, the preservation of bearings
b, cleaning of bearings and their surroundings

e, post-installation check
f, disassembly work

Bearing storage
The bearings are coated with an appropriate amount of anti-rust oil and packaged with anti-rust paper. As long as the package is not damaged, the quality of the bearing will be guaranteed.
However, for long-term storage, it is recommended to store on a shelf 30cm above the ground at a temperature below 65% and a temperature of about 20 degrees Celsius. In addition, {TodayHot} storage places should avoid direct sunlight or touch with cold walls.
Bearing installation
Pre-installation precautions
1) Bearing preparation
Since the bearings are rust-proofed and packaged, do not open the package until installation.
In addition, the anti-rust oil coated on the bearing has good lubricating properties, and can be used directly for bearings for general purpose or for bearings filled with grease without cleaning. However, for instrument bearings or bearings for high-speed rotation, the cleaning oil should be washed with a clean cleaning oil. The bearing is prone to rust and cannot be placed for a long time.
2) Inspection of the shaft and the casing
Clean the bearing and the casing to confirm the burrs left by scratches or machining. There must be no abrasive (SiC, Al2O3, etc.) sand or chips in the outer casing.
Secondly, check whether the size, shape and processing quality of the shaft and the casing are in accordance with the drawings.
Before installing the bearing, apply mechanical oil to each mating surface of the tested shaft and the outer casing.
Bearing installation method
The mounting method of the bearing varies depending on the type of bearing and the fitting conditions.
Since the shaft is generally rotated, the inner ring and the outer ring can respectively adopt an interference fit and a clearance fit, and when the outer ring rotates, the outer ring adopts an interference fit.
(1) Press-in installation
Push-in installation generally uses a press, and bolts and nuts can also be used. When necessary, the hammer can be used.
(2) Hot sleeve installation
The hot-sleeve method of heating the bearing in the oil to expand it and then mounting it on the shaft can prevent the bearing from being subjected to unnecessary external force and complete the installation work in a short time.
Heating precautions:
1) Do not heat more than 100 degrees Celsius.
2) Do not allow the bearing to contact the bottom of the oil sump.
In addition, the hot-sleeve installation can also use an induction heating device to heat the bearing to expand it and then mount it on the shaft.
Bearing disassembly
When you regularly inspect or replace parts, you need to remove the bearings. Usually the shaft and bearing housing are almost always used, and the bearings are often used. Therefore, the structural design should take into account that when removing the bearing, {HotTag} does not damage the bearing, shaft, bearing housing and other parts, but also prepare appropriate disassembly tools. When removing the statically fitted ferrule, only the pulling force can be applied to the ferrule, and the ferrule must not be pulled by the rolling element.
Bearing maintenance
In order to fully utilize the bearings and maintain their proper performance for a long time, regular maintenance (regular inspection) must be performed.
Through proper periodic inspections, early detection of failures and prevention of accidents are important to improve productivity and economy.
