ABSTRACT:
A capstan or pressure roller shaft is journalled in a single one-piece elongated bearing member having a bearing surface sufficient to define radial position and inclination of the shaft. The bearing member is aligned with respect to a mounting support on the tape recorder, to adjust shaft alignment, by two axially spaced cylindrical positioning surfaces which are received in axially spaced cylindrical receiving surfaces in the support. At least one of the positioning surfaces is eccentric with respect to the bearing member, and is fixed to the bearing member so that rotation of the bearing member about an axis defined by the receiving surfaces adjusts the inclination of the shaft. The shaft inclination may be adjusted by inserting a tool into the tape recorder, engaging a journal formed in a mounting support adjacent the bearing member, the tool having a gear which engages a toothed portion on the bearing member for rotating the bearing member about the support axis defined by the support receiving surfaces.
