for Y-bearing plummer
block units
with a composite or cast housing and grub
screws
1 Mount any components that are on the
shaft between the two Y-bearing units.
2 Slide the Y-bearing plummer (pillow) block
unit onto the shaft with its locking device
facing outwards.

but do not tighten them.

steps 2 and 3.
5 Carefully align both Y-bearing units, using
the shaft. Fully tighten the attachment bolts
or nuts in the housing base.
6 Align the shaft in the bearing arrangement
axially and – if possible – turn it a few times.

of both units to the tightening torque indi-
cated in table 1 on page 54 († fig. 1).
