5 Cylindrical bearings 5.1 Dimensions Dimensions for cylindrical bearings are shown in Figure 1, Table 1 and Table 2. 5.2 Tolerances
The tolerances for the bearings after fitting and the tolerances for the housing and insertion pin are given below. In addition, the tolerances for the inside and outside diameters of the bearings before fitting are given. Since the actual tolerances and combinations of tolerances in the as-delivered state depend upon the characteristics of the materials and the manufacturing methods, they should be discussed with the manufacturer.5.2 Tolerances The tolerances for the bearings after fitting and the tolerances for the housing and insertion pin are given below. In addition, the tolerances for the inside and outside diameters of the bearings before fitting are given.
Since the actual tolerances and combinations of tolerances in the as-delivered state depend upon the characteristics of the materials and the manufacturing methods, they should be discussed with the manufacturer.A cylindrical surface is permissible on the sphere at the centre of the bearing length, the diameter of which should be agreed upon by the user and the manufacturer.
