1. Proper Installation Steps for Insert Bearings with Housings

1.1 Prepare the Shaft

Clean the shaft thoroughly – remove rust, burrs, and old adhesive.

Check shaft diameter tolerance (h6 or j6 recommended).

Too tight = bearing deformation. Too loose = vibration.

1.2 Align the Housing

Mount the housing on a flat, clean surface.

Use a feeler gauge or dial indicator to check alignment between shaft and housing.

1.3 Apply Lubrication Before Mounting

BCHH bearings come pre‑greased, but add a thin layer of grease on the shaft contact area to prevent fretting corrosion.

Avoid over‑greasing – it may push out seals.

1.4 Choose the Correct Mounting Method

For set‑screw locking type:

Tighten the two set‑screws evenly in a cross pattern.

Use a hex wrench – do not overtighten.

For eccentric locking collar type:

Rotate the collar in the direction of shaft rotation.

Tap it gently with a brass rod, then lock the set‑screw.

General rule:

Never hammer directly on the bearing or housing.

Use a soft metal tube or mounting sleeve that contacts only the inner ring.

1.5 Final Check After Mounting

Rotate the shaft by hand – it should turn smoothly with no unusual noise or resistance.

Measure radial play if required.

2. How to Dismount Without Damaging the Bearing

Disconnect power – safety first.

Loosen locking devices – set‑screws or eccentric collar.

Use a bearing puller – grip the inner ring only. Never pull on the outer ring or housing.

Remove housing bolts – then clean and inspect the housing for cracks.

Check the shaft – polish lightly if scoring is found.
