Define bearing characteristic number
WebA sleeve bearing's operating mode is described in terms of a bearing characteristic number. A. The value of A, in relation to other factors, determines whether or not the bearing will operate hydrodynamically. … WebFor example bearing 6303, will have bore diameter 17 mm. If bearing will have a bearing number with last two digits 04 or more than 04, in this case bearing bore diameter could be easily calculated by multiplying the last …
