Cone Stand. Cone stand<br />
is a measure of the<br />
variation in cone raceway<br />
size, taper and roller<br />
diameter. This is checked<br />
by measuring the axial<br />
location of the reference<br />
surface of a master cup<br />
or other type gage with<br />
respect to the reference<br />
cone face.<br />

Cup Stand. Cup stand is a<br />
measure of the variation<br />
in cup I.D. size and<br />
taper. This is checked<br />
by measuring the axial<br />
location of the reference<br />
surface of a master plug<br />
or other type gage with<br />
respect to the reference<br />
face of the cup.<br />
(1) Not all types and sizes are listed in this catalog. Please contact your <strong>Timken</strong> representative <strong>for</strong> further in<strong>for</strong>mation.<br />
(2) These sizes manufactured as matched assemblies only.<br />
(3) Stand <strong>for</strong> flanged cup is measured from flange backface (seating face).<br />
