AuGlideTM, SY and SP bushes should be inserted into the bearing housing with the aid of a stepped mandrel. Care must be taken to insert the bush squarely into the housing to avoid damage to the bearing lining material. A slight lead-in chamfer should be machined in the housing and a smear of oil applied to the outside surface of the bush to assist the fitting operation. Recommended mandrel and chamfer dimensions are given in figure 4.

1) Inside diameter alignment for common bushings
Normally the bushing can be immediately put into use after it has been fixed. But if there’s need to enlarge the matching clearance or due to too much surplus the inner bore of the bushing deformed, we can use the following showed molding tools to make the inner bore meet the required dimensions. Diameter of the molding tools shall not be too big; otherwise, life of the bushing may decrease. Please see the picture.

2) Alignment of the mating arbor
In order to avoid load centralization, when fitting the bushing, radial or axial movement, parallelism between the bushing and the arbor must be aligned. It requires the parallelism not exceed 0.02mm.
