a Single plane mean bore diameter deviation of central shaft washer (∆
dmp ) and outside diameter
(∆ Dmp ) variation. b Raceway parallelism with the face, housing-mounted ( S
e ) and bore-mounted ( S i ) race or washer.
c Deviation of the actual bearing height. All dimensions in micrometers, unless otherwise indicated. Tolerances are for normal tolerance class only. For sizes beyond the range of this table and for other tolerance class values, see Standard. All entries apply to type TA bearings; boldface entries also apply to type TS bearings. Table 9.
