This is the first time I've ever contemplated using a drawn cup needle roller bearing and I'm a little unsure of the process and problems/issues. I'm intending to use it in Aluminium and I'm puzzled about the housing tolerances. My intended size is 10mmx14mmx10mm. The table on the right specifies an R6 or R7 tolerance for alloy, which when I looked it up on the net, appeared to be exactly the same as H6 H7. Can anyone tell me the reason for the change of letter (H to R) ? I sort of planned on getting a 14mm H7 reamer and then just pressing them in (although I have no idea of the force needed), possibly with bearing lock or epoxy to retain, depending on insertion force. I intend on using silver steel for the running shaft.
Any help or advice about these bearings much appreciated.
