Radial Clearance Radial Clearance EhsanFat (Mechanical) (OP) 30 Jun 15 15:52 Does anybody know what TBC stands for in roller bearing radial clearance? RE: Radial Clearance JJPellin (Mechanical) 30 Jun 15 20:57 Our procedure for setting the clearance in a tapered roller bearing includes a requirement to measure the clearance at Top Dead Center (TDC). I am not familiar with TBC. Are you sure it is a "B" and not a "D"? Perhaps it is a typo?

RE: Radial Clearance EhsanFat (Mechanical) (OP) 1 Jul 15 11:05 I have searched in literature, and I think TBC stands for To Be Confirmed! http://files.engineering.com/getfile.aspx?folder=b58848cf-255a-4a54-975b-3b RE: Radial Clearance BearingDave (Mechanical) 25 Jul 15 19:12 The typical abbreviation for bearing clearance is RIC (Radial Internal Clearance). I have never heard of TBC other than "to be confirmed" or "to be continued" which has nothing to do with bearing terminology.
