Shaft press fit tolerance chart. The calculator which calculates press fit. 4 mh 1 medias schaeffler technologies page tables dimension and tolerance symbols. According to nominal size and fit type selection among running and sliding rc locational clearance lc locational transition lt locational interference ln force and shrink fn fits size limits for holeshaft are calculated with schematic representation of the fit. Ansi limits and fits calculator works in line with ansi b41 standard which is based on inch units.
Simply bearings ltd providing iso limits and fits for your bearing and bushing needs. This concept is illustrated in the figure below for both clearance and interference fits. The size ranges given are for typical size ranges utilized within industry. Whenever possible selection of tolerance class shall be done among these tolerances to avoid too many numbers of tools and gauges.
9 normal tolerances normal tolerances for fag. 5 shaft and housing fits. Conversely an interference fit is a fit where there will always be overlap in the joint between the specified mating shafthole even at the minimum material condition values allowed by the shaft and maximum value allowed by the hole tolerance values ie the largest hole and the smallest shaft. The following links are to general tolerance table charts for standard shaft hole fits per mcdonald douglas design guide machining tolerances.
