Ⅰ. Preparation before installation
Check the bearings and accessories
Confirm that the bearing model and size match the equipment.
Check whether the bearing seat, seal ring, and fasteners are intact and free of damage or rust.

Clean the bearing seat hole and shaft surface to remove burrs, oil stains or impurities.
Lubrication: Spherical bearings are usually pre-installed with grease (such as lithium-based grease). If refilling is required, add according to the instructions (generally fill 1/3~1/2 of the internal space of the bearing).
Tool preparation: rubber hammer/soft copper hammer, hydraulic press (if press-fitting is required), torque wrench, heating equipment (for hot fitting).

Ⅱ. Installation steps

1. Install the bearing on the shaft
Cold installation method (common)
Align the inner ring of the bearing with the shaft neck, tap the inner ring of the bearing with a hammer (do not directly hit the outer ring or seal, or use a press to apply pressure evenly to ensure that the bearing is pressed into the shaft neck in parallel to the designed position.
Hot installation method (when the interference is large)
Heat the bearing to 80~100℃ (oil bath or induction heating), quickly insert it into the shaft neck, and tighten it after cooling.

2. Fix the bearing
Locking method
Top screw fixing (common): Use an inner hexagon wrench to tighten the top screw on the inner ring of the bearing and press the plane on the shaft (make sure there is a matching plane on the shaft).
Eccentric sleeve fixing: Put the eccentric sleeve on the shaft, rotate the eccentric sleeve to lock it, and then fix it with bolts.
Fixed sleeve fixing: Adjust the bearing position and lock it with the adapter sleeve and nut.

3. Install the bearing seat
Install the bearing into the bearing seat, making sure the outer spherical surface fits the seat hole.
Fix the bearing seat to the equipment base with bolts, tighten the bolts step by step in diagonal order to avoid deflection.

4. Adjustment and sealing
Clearance check: Manually rotate the bearing to ensure there is no sticking or abnormal sound.
Seal confirmation: Check whether the seal is in place to prevent dust or liquid intrusion.
