Bearing tolerance
The tolerance of the rolling bearing
The tolerance and the precision of the rotation of the rolling bearing are shown in Table2-Table9, according with requirement of GB307.1-94, and equivalent to the standard ISO492-1981, ISO199-1979.
The definition of the centripetal bearing tolerance
Insider diameter
d--tolerance of insider diameter; ds--single inner diameter
d1--tolerance of outsider dimension; dmp--the average diameter in a single plane
△dmp--the average deviation of insider diameter in a single plane, △dmp=dmp-d（for tapered bore hole △dmp refer only to the samll end of the tapered hole theory)
△ds——the deviation of diameter of the single bore，△dmp=d1mp-d1；
Vdmp——The average variate in volume of insider diameter, the average discrepancy between the maximum and minimum of the insider diameter in a single plane.
Vdp--the variate in volume of insider diameter in a single ridial plane, the average discrepancy between the maximum and minimum of the insider diameter in a single axial plane.
d--outersider diameter; ds--single insider diameter
Dmp--the average of outsider diameter in a single plane; △Ds——single outsider diameter deviation，△Ds=Ds-D；
△Dmp——the average of outsider diameter deviation in a single plane，△Dmp=Dmp-D；
VDmp——the variate in volume of insider diameter in a single plane ，the discrepancy between the maximum and minimum of the outsider diameter in a radial plane，VDp=Dsmax-Dsmin；
VDmp--the average variate in volume of outersider diameter, the average discrepancy between maximum and minimum of the outsider diameter in a single plane.
B（C）——the metric width of insider ring(outsider ring)； Bs（Cs）——the singleness width of insider ring(outsider ring)；
△Bs——the deviation of the singleness width of inner ring，△Bs=Bs-B；Cs——the deviation of the singleness of outsider ring，Cs=Cs-C；
VBs——the variation of width of insider ring，the discrepancy between the maximum and minimum of the width of single outsider ring，VBs=Bsmax-Bsmin；
Vcs--the variation of the width of outsider ring, the discrepancy between maximum and minimum of the signlesness width of single outsider ring
T-bearing metric width
△Ts——deviation of measured bearing width，△Ts=Ts-T； rotation accuracy
Kia）——ridial runout of assembled bearing inner ring； Kea——ridial runout of assembled bearing outer ring；
Sd——beat of the base end face of the inner bore； Sd——The degree inclination of outer surface generation line relative to base edge；
Sia--The vibration of complete set inner ring edge relative to race way, Sea--The vibration of complete set outer ring edge relative to race way
