Understanding Journal BearingsEDGE
ClearanceThe basic guideline universally used for diametral journal bearing clearance is 1.5 mils per inch of journal diameter That is a 4 inch diameter shaft would need about 6 mils of diametral clearance Always check if the specifications yousee are for diametral clearance Some manufacturers specify radial clearancewhich is really difficult to measure Ifthe application has atypical loads and/or speeds then this clearance rule may need to be adjusted The bearing shouldbe held in the housing with a zero to 1 mil interference fit A loose bearing will have vibration problems and too muchhousing interference can reduce the clearance in the bearing The issue of tolerances should also be considered Clearance values are usually given as a range The limits suggested here for minimum allowable clearance

Bearing radial clearance explained
Axial The total internal clearance is the amount that one ring can be displaced relative to the other ring either radially or axially The radial clearance is the total clearance between the raceway and the rolling elementsmeasured normal to the bearing axis The clearance changes with the expansion or contraction of the bearing rings.

How to Check Bearing ClearancesK1 Technologies
After measuring all eight rod bearing clearances and using shell halves to set the clearances it s very common to have a clearance spread between the rods of perhaps 0.0004 to 0.0005 inch Let s say our loosest rod bearing measured 0.0028 inch while the tightest rod came in at 0.0023 inchcreating a spread of 0.0005 inch.
