with a composite (Y-TECH) or cast housing
and an eccentric locking collar

1 Mount any components that are on the
shaft between the two Y-bearing units.
2 With the eccentric locking collar removed,
slide the flanged Y-bearing unit onto the
shaft with the locking device facing
outwards.
3 Fasten the Y-bearing unit securely to the
machine wall.
4 Mount the other flanged Y-bearing unit
to the opposite end of the shaft, following
steps 2 and 3.
5 Align the shaft in the bearing arrangement Fig. 2
axially and – if possible – turn it a few times.
6 Place the eccentric locking collars on the
inner ring of both Y-bearings and snug
tighten them in the main direction of rotation
(† fig. 1).
7 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. 2).
8 Tighten the grub screw in the eccentric
locking collar of both units († fig. 3) to the
tightening torque indicated in table 1 on
page 54.
