The cause of bearing damage:

Bearings are precision parts, so when use requires a fairly cautious attitude, even if is the use of high performance bearing, if use undeserved, also cannot achieve the expected performance effect, and easy to make the bearing damage, so use bearing should pay attention to the following items:

A clean, keep bearing and the surrounding environment

Even tiny dust into the bearing of invisible to the naked eye, also will increase the wear of bearings, vibration and noise.

Second, be careful when using installation

Do not allow the powerful punch, are not allowed to use hammer percussion bearing directly, don't allow through the transfer roller pressure.

Three, use appropriate and 

accurate installation tools

Use special tools as far as possible, avoid using cloth class and 

short fiber, things like that.

Fourth, to prevent the bearing rust

Directly with the hand take bearing, want to wash hands fully the sweat, and again after coated with high quality mineral oils, especially in the rainy season and summer to pay attention to rust.

Bearing installation remove the basics:

(1) use a clean, kerosene or gas bearing and matching related parts clean;

(2) check the bearing ready to use the original models, matching parts size is qualified;

(3) with a dedicated assembly tools to press the bearing into the sleeve, tool sleeve diameter shall not exceed the bearing guard outside diameter,When assembling the strength should be uniform, do not impact and brutal assembly;

(4) bearing after the installation should be rotating bearings and related parts, see if any cassette phenomenon and abnormal noise; According to the requirement of the host components into the specified lubricating grease and lubricating oil;

(5) in the bearing and the bearing and shaft assembly, seat hole between surplus quantity larger when the product must be carried out on the bearing oil bath heating, the oil temperature at 80 degrees Celsius;

(6) bearing is disassembled, must use a special tool drawing class, it is forbidden to use the iron tapping bearing directly;

(7) bearing assembly and disassembly, should avoid to keep rolling body, the stress and deformation.
