New bearing: 40 mm inside diameter, 44mm outside diameter.
Defect bearing: ≥ 42,2 mm inside diameter.
Measure the diameter several places to get the correct impression of the bearing ovality.
Large type, 50 mm
New bearing: 50 mm inside diameter, 55 mm outside diameter
Defect bearing: ≥ 52,7 mm inside diameter.
Measure the diameter several places to get the correct impression of the bearing ovality. The material
thickness in bearings must under no circumstances be ≤ 0,2 mm. If so, the bearing is defect and must be
replaced immediately. The reason is to avoid serious damage to the rollers axle, and potential mechanical
breakdown.
Figure 7.32 :
Example picture of plain bearing. New bearing to the left, and worn out/defect
bearing to the right.
NOTE: Good practice is to change the bearings before reaching the maximum degree of wear.
7.12.3 Remove sprockets
The sprockets are fastened to the axle with an eccentric connection. Follow this procedure to loosen the
sprockets.
1. Make an indication mark across both the sprocket and axle (red line) that indicates movement
between the axle and the sprocket.
2. Set a solid steel bar on one of the sprocket teeth, and hit it with a hammer (opposite of the
sprocket working direction).
3. Remove the sprocket, when the indication mark has shifted.
