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

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