Product data Page ................4Page ..............16 Radial spherical
plain bearings manufacturer requiring maintenance Table and those of inch-size bearings are given in Dimensions The dimensions of spherical plain bear-
ings of series GE, GEH and GEG con-
form to ISO 12240-1:1998. Bearings with cylindrical extensionsto the inner ring, series GEM, have a non-standard inner ring width but
otherwise have the dimensions of
series GE bearings.The dimensions of spherical plainbearings with inch dimensions, series
GEZ, conform to the American Stand-
ard ANSI/ABMAStd.22.2-1988. Tolerances Table on page 60 The tolerances to which metric radial
spherical plain bearings are made are
given in . Outer ring tolerances applyto conditions before fracture and sur-
face treatment. Acccordingly, inner
ring tolerances apply to rings before
surface treatment.The tolerances are in accordance with ISO 12240-1:1998 (metric) and
ANSI/ABMA Std. 22.2-1988 (inch-size
bearings).The symbols used in the tolerancetables are explained in the following.dnominal
