Let me answer. The investigation of 23052 spherical roller bearing inner diameter 260mm diameter 400mm thickness of 104mm bearing. I don't know where you use it here. According to the national general standard (see mechanical design manual). The following is recommended according to the load form tolerances distinguish axis, the pore size tolerance due to more according to different conditions can choose P, N, M, K, J, H (6 or 7) according to the condition, also should be based on the bearing manufacturer's recommended installation.
For shafts, there are the following rules:Normal load (0.13c < P < 0.26C this parameter does not understand the words refer to the bearing load) 140 < d < 280 P6 tolerance selection.Under heavy load (0.18c < P) 200 < D, the axial tolerance is r7.
For the bearing tolerance is generally in the hole H6 outer H7, of course, also may not be the same as the safest way is to ask the supplier to the tolerance grade and tolerance, is very important for bearing tolerances so large, slightly careless may be an accident.
