I. Installation of sealed pillow block bearings:
1.Check the accuracy of the shaft
Before installing the bearing, first check whether the dimensional tolerance of the shaft is qualified, whether the shaft is bent, bumped, burred, etc., and add some lubricant to the shaft appropriately.

2. Check the rigidity and flatness of the mounting surface
The rigidity of the mounting frame with the sealed pillow block bearings should be sufficient, and the flatness of the mounting part should not be greater than 0.15mm.

3.install sealed pillow block bearings
Avoid hitting the sealed pillow block bearings with metal objects such as hammers for installation. Especially for a bearing with a retaining ring seal, when the sealed pillow block bearings is struck, it may cause the retaining ring to move inward, contact the inner sealing ring and cause friction during operation, causing the bearing to fail to rotate or the temperature to rise sharply and burn the bearing. When the inner hole of the sealed pillow block bearings and the shaft fit tightly, it is recommended to use a pressure device to press the end face of the inner ring for installation.

4. Pre-tensioned sealed pillow block bearings
Excessive torque of the locking bolt may cause deformation of the sealed pillow block bearings seat, and the appropriate tightening torque is required to tighten the bolt. It is recommended to use the locking bolt with a washer when installing the sealed pillow block bearings seat, because if the locking bolt is used alone to lock Bearing housing, locking bolts may damage the bearing housing.

5. Tighten the bearing top wire
Tighten the top screw according to the recommended torque. pillow block bearings

6. Tight sealed pillow block bearings
Excessive torque of the locking bolt may cause deformation of the sealed pillow block bearings seat.Use appropriate tightening torque to tighten the bolt.

Second, the installation of eccentric sleeve locking sealed pillow block bearings:
Note: Products with eccentric sleeves are not recommended for situations where the direction of rotation will change, because changes in the direction of rotation will cause the eccentric sleeve to loosen. The preparation for products with eccentric sleeves is the same as for products with top wires.

3.Eccentric sleeve
Assemble the eccentric sleeve on the inner ring boss, and manually rotate the eccentric sleeve in the direction of shaft rotation to temporarily tighten it. cheap price pillow block bearing

4. Turn the eccentric sleeve
Insert the tool rod into the cylindrical recessed hole of the outer diameter of the eccentric sleeve, and tap the tool rod to make the eccentric sleeve rotate in the shaft rotation direction, and hold the mounting shaft tightly. block bearing

5.Lock the eccentric sleeve
Tighten the top wire on the eccentric sleeve to the shaft. See the product manual for recommended tightening torques. pillow block

6. Tight sealed pillow block bearings
Excessive torque of the locking bolt may cause deformation of the sealed pillow block bearings seat. Use appropriate tightening torque to tighten the bolt.
