Bearing fit chart shaft and housing the following tables are a guide for establishing shaft and bearing fits for miniature and instrument bearings when the expansion coefficients of the shaft and housing are similar or when the operating temperature differential between them is nominal
The quality of a bearing arrangement is decisively influenced by the components shaft housing seal that are directly adjacent to the bearing seals play a decisive role in protecting bearings against contamination if inadequate seals are used contaminants can penetrate the bearing or an unaccept ably large quantity of lubricant
Mounting instructions are either printed on the inside of the bearing box or included as a leaflet when mounting or dismounting superprecision bearings all recommendations and guidelines valid for rolling bearings should be considered mounting and dismounting
Support for the bearing is provided by framing beneath the steering gear deck there is thicker deck plating in the area beneath the carrier bearing and the latter may be supported on steel chocks the base of the carrier bearing is located by side chocks welded to the deck the carrier may be of meehanite with a gunmetal thrust ring and bush
Jun 25 2001 fixed and floating bearings most shafts have at least two bearings supporting them it is advisable to fix only one bearing per shaft so that one is locked from axial movement while the other is allowed to float this technique is critical on fans that run at high speeds or for bearings that are spaced more than 2ft apart on a shaft
