Installation of eccentric sleeve locking bearing

Note: Products with eccentric sleeves are not recommended for applications where the direction of rotation changes, because changes in the direction of rotation can cause loosening of the eccentric sleeve. The preparation work for products with eccentric sleeves is the same as that for products with top threads.

1. Bearing with seat

To avoid hitting the bearing with a metal object such as a hammer for installation. Especially for bearings with retaining ring seals, when the bearing is struck, the retaining ring may be displaced inwards, contacting the inner sealing ring and causing friction during operation, causing the bearing to fail to rotate

Or the temperature rises sharply and the bearing is burnt out. When the inner bore of the bearing and the shaft are tight, it is recommended to use a pressure device to press the end face of the inner ring for installation.

2. Pre-tightened bearing seat

Excessive torque of the locking bolt may cause deformation of the bearing housing, and it is necessary to use the appropriate tightening torque to lock the bolt. Zhongda Bearing recommends that the locking bolt be used with a gasket when installing the bearing housing, because if the locking is used alone Bolt lock

Holding the bearing housing, the locking bolt may damage the bearing housing.

3. Install eccentric sleeve

Fit the eccentric sleeve to the boss of the inner ring, and manually turn the eccentric sleeve in the direction of shaft rotation to temporarily tighten.

4. Turn the eccentric sleeve

Insert a tool bar into the cylindrical concave hole of the outer diameter of the eccentric sleeve, and hit the tool bar to make the eccentric sleeve rotate in the direction of shaft rotation and tightly hold the installation shaft.

5. Lock the eccentric sleeve

Tighten the jacking screw on the eccentric sleeve to the shaft. Refer to Zhongda Bearing Product Manual for recommended tightening torque.

6. Retighten the bearing seat

Excessive torque of the locking bolt may cause deformation of the bearing housing, and it is necessary to use the appropriate tightening torque to lock the bolt.
