Mounting instructions
for flanged Y-bearing units

with a pressed steel housing and
an eccentric locking collar

1 Mount any components that are on the
shaft between the two Y-bearing units.
2 Place one housing half into position on
the machine wall with threaded fasteners
(† fig. 1).
3 With the eccentric locking collar removed,
slide the Y-bearing onto the shaft and into
the housing half with the locking device
facing outwards.
4 Place the second housing half into position
over the Y-bearing († fig. 2).
5 Fit the threaded fasteners (nuts or bolts),
but do not tighten them.
6 Mount the other Y-bearing unit at the other
end of the shaft, following steps 2 through 5.
7 Tighten the threaded fasteners holding the
flanged units in place.
8 Align the shaft in the bearing arrangement
axially and – if possible – turn it a few times.
9 Place the eccentric locking collars on the
inner ring extension of both Y-bearings and
snug tighten them in the main direction of
rotation († fig. 3).
10 Tighten the locking collars to their final
position using a hook spanner with a stud
engaging the hole in the circumference of
the collar († fig. 4).
11 Tighten the grub screw in the eccentric
locking collar of both units († fig. 5) to the
tightening torque indicated in table 1 on
page 54.
