Features and Applications:
Double Row Structure:
Unlike single row bearings, these bearings consist of two rows of balls, which allows them to carry more axial loads in two directions.
Contact Angle:
The contact angle of these bearings is usually 30 to 40 degrees, and this angle determines their ability to carry axial loads.
Ball Groove:
Some types of these bearings have ball grooves on one or both sides. These grooves are used to facilitate installation and increase the bearing's load capacity.
Applications:
These bearings are used in applications that require simultaneous axial and radial loads in two directions, such as industrial gearboxes, pumps, and machine tools.
Advantages:
Among the advantages of these bearings are the ability to withstand axial loads in two directions, high strength, and relatively compact dimensions. Important points in installation:
Load direction:
In ball-groove bearings, it should be noted that the main axial load direction is towards the side without the bearing groove.
Installation method:
Installation of these bearings must be done carefully and using appropriate tools to prevent damage to the bearing and other parts.
Lubrication:
It is very important to use the appropriate grease to lubricate these bearings in order to increase their useful life
