6307 bearing technical reference:
Tolerances
Radial Ball, Spherical and Cylindrical Roller Bearings
Depending upon requirements, various degrees of bearing accuracy may be required.
Among the tolerance classes PO applies to ball bearings for normal useage. The other classes P6, P5, P4, P2 apply to ball bearings of increased precision as required.
PO applies to roller bearings for normal usage. P6 and P5 apply to roller bearings of increased precision as required.
Tolerances Symbols-inner Ring
△Dmp
Single plane mean bore diameter deviation from basic bore diameter, i. e. bore tolerance for a basically tapered bore, △Dmp refers only to the theoretical small bore end of the bore.
Kia
Radial runout of assembled bearing inner ring, i. e. ,radial runout of raceway.
Vbs
Inner ring width variation, i. e. parallelism.
Sd
lnner ring reference face runout with bore, i, e. squareness bore to face.
Sia
Axial runout of assembled bearing inner ring, i. e.lateral(axial)runout of raceway.
△Bs
Single inner ring width deviation from basic, i. e.width tolerance.
Tolerances Symbols-outer Ring
△Dmp
Single plane mean outside diameter deviation from basic outside diameter,i. e. O. D. tolerance.
Kes
Radial runout of assembled bearing outer ring, i. e. ,radial runout of raceway.
Vcs
Outer ring width variation, i. e. parallelism.
Sd
Outside cylindrical surface runout with outer ring reference face, i. e., squareness O. D. to face.
Sea
Axial runout of assembled bearing outer ring, i. e lateral(axial) runout of raceway.
△Dmp
Outer ring width deviation from basic, i. e. , width
tolerance.
