Tolerances

Different occasion needs different precision.

According to the tolerance grade,P0 is applicable to the roller bearing under normal conditions,while P6 is applicable to high precison roller bearing.

Code--inner ring

△dmp：single plane mean bore diameter deviation(For the tapered bore, △ dmp refers to the theoretical small end only.)

Vdp：variation in a single radial plane

Vdmp：mean bore diameter variation(applicable for straight bore only)

Kia：radial runout of assembled bearing inner ring

△Bs：deviation of a inner ring width,i.e.,width tolerance

VBs:inner ring width variation,i.e.,parallel tolerance

Code--Outer ring

△dmp：single plane mean outside dia. Deviation,i.e.,outside dia.tolerance

VDp：single plane outside dia. variation

VDmp：mean outside dia.variation

Kea：radial runout of assembled bearing outer ring

△Cs：offset of single outer ring width,i.e.,width tolerance

VCs：outer ring width variation,i.e., parallel tolerance
