Installation Instructions

(1)Inspection of components before installation

Clean the bearing housing or other mounting parts, remove the dirt, and confirm whether the burrs of each

part have been removed.
 

(2) Install it on the bearing seat or shaft

Because it is a thin-walled bearing, it is easy to tilt during installation. Please use a plastic hammer to find the

level and tap it evenly in the circumferential direction, and install it little by little.

Until you can confirm the contact surface is fully seated by sound.
 

(3) Installation method of side compression flange
 

1.  After placing the side compression flange in position,

place it in the circumferential direction.

Shake back a few times to adjust the position of the

mounting bolts.

2.  Install the compression bolt, and make sure that

there is no deviation due to the bolt hole when tightening the

bolt by hand.

The distance causes the bolts to be difficult to screw in.

3.  The tightening of the compression bolt can be

divided into 3-4 parts from temporary tightening to final

tightening stage, repeat the tightening in the order on the

diagonal. When tightening is divided into two parts

When tightening the inner or outer ring press bolts, the

integral outer ring is often tightened during the tightening

process.

Or the inner ring can be adjusted and rotated a little to make the outer ring divided into two parts or the

deviation of the inner ring is corrected.
 

Special design: If you need special structure (such as outer ring with mounting holes, inner ring without

holes, etc.), non-standard size, special materials or high precision requirements, etc., please contact.
