NJ344 Bearing clearance
C1-1 set of the clearance, clearance is less than 2 groups.
C2 - clearance conform to the standards stipulated by the two groups, group windage is less than 0.
C0 - clearance conform to the standards stipulated by the 0 group, code omitted, don't say.
C3 - clearance conform to the standards stipulated by the three groups, group clearance greater than 0.
C4 - clearance conform to the standards stipulated by the four groups, clearance is greater than three groups.
Of the C5 - clearance 5 groups, clearance is greater than the four groups.
When clearance code and tolerance grade bearing code P4, P5 or P6, saves clearance code C.
