Mounting and Dismounting of Rolling Bearings - Schaeffler Group

a b
Yoke Type Track Rollers
Since, in most cases, the inner ring of yoke type track rollers is subjected
to point load, a tight fit on the shaft is not required. On mount -
ing, ensure that the lubricating hole is located in the unloaded raceway
zone. The outer ring of yoke type track rollers without axial guid
ance must be guided by lateral backing surfaces.
Stud Type Track Rollers
On mounting stud type track rollers, the radial lubricating hole should
be located in the unloaded zone of the raceway.
On mounting a stud type track roller in the through-hole of a machine
frame, the stud must usually be secured against rotating when
tightening the nut. This is enabled by a slot at the flanged end of the
stud (Fig. 25).
