Stainless steel bearing fit tolerance level and tolerance zone of 25)

Stainless steel bearing fit tolerance level and tolerance zone of 25) Stainless steel bearing fit tolerance level and tolerance zone is how to choose? I/small hong guess, a lot of people in this respect are foolish, perhaps only know the first two, probably. For I/small hong, in fact, is the same. However, in order to popularize knowledge of bearing, I still choose to continuous efforts, continuous learning. Here is my/small hong from knowledge for reference in other parts of the country. The selection of tolerance grade and stainless steel bearing fit tolerance grade of the shaft or the bearing hole associated with bearing accuracy. Cooperate with P0 level precision bearing shaft, its tolerance level for IT6 commonly, bearing hole for IT7 commonly. Have higher request for rotating accuracy and operational stability of occasions ( Such as motor, etc. ) , should choose shaft for IT5, bearing hole for IT6. 2 the choice of tolerance zone equivalent radial load P into the 'light', 'normal' and 'heavy' load several ways, such as its ties with dynamic load rating of bearing C for: light load P≤ 0. 0 06 c normal load. 06 c < P≤ 0. 12 heavy load 0 c. 12 c < P1) Shaft assembly tolerance zone of centripetal bearing and angular contact bearing shaft reference table corresponding tolerance zone of tolerance zone. For most occasions, shaft rotation and radial load direction invariable, the bearing inner ring relative to the loading direction, generally should choose the transition or interference fit. Static axial and radial load direction invariable, the bearing inner ring relative to the direction of the load is stationary, can choose transition or small clearance fit ( Too big gap is not allowed) 。 2) Shell hole tolerance zone installation centripetal bearing and angular contact bearing shell hole tolerance table with reference to the corresponding tolerance zone. Pay attention to when the choice for the direction of the load swing or rotation of the outer ring, should avoid clearance fit. Equivalent radial load also affects the size of the outer ring of choice. 3) Bearing structure form selection of rolling bearing of stainless steel bearing seat unless you have special need, the integral structure more commonly, split bearing just have trouble in the assembly, or on the advantages of convenient assembly become main consideration when using, but it cannot be applied to tight fit or with more precision, such as K7 and than K7 tighter fit, and like a tolerance level for IT6 or more precision of hole, are not allowed to adopt split housings.
