Special Note:
1, Sometimes the cages will be different.
eg.: 67 series thin-walled bearings, because the inner wall is very thin, will use the crown-shaped iron cage.
2, The grease and sealed are accept custom-made, so sometimes there are different colors of the rubber sealed.
If you mind the sealed color, please contact us.
3, The standard clearance of bearings is ISO standard C0, the United States standard K25, the clearance value is 3-18um.
This Bearing Cover
Compared to the open type, the shielded and sealed bearing types provide better protection from contamination and grease leakage.
They are selected based on the application type and environment.
This is 2RS double sealed.
This Bearing Lubrication
One of the most important elements required
for the effective function of bearing arrangements is correct lubrication.
The lubricant separates the metallic bearing
surfaces and thereby reduces friction, preserves the steel parts and acts as an additional barrier against the entry of contaminations or impurities into the bearings.
This Bearing Cage
Retainers keep the balls separated and equally spaced.
Retainer types are set based on the bearing size but can be selected based on the required performance.
This is made of Nylon PA66 Cage.
This Bearing Material
The most common material used to produce the load carrying components in roller bearings is 52100 chrome steel (bearing steel).
These components are the bearings inner and outer rings, balls and rollers.
The chemical composition of this steel has high carbon and about 1.5% chromium content.
