Mounting instructions
for Y-bearing plummer
block 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 With the eccentric locking collar removed,
slide the Y-bearings onto both shaft ends
with the locking device facing outwards.
Install the rubber seating ring on the out-
side diameter of the bearing (optional).
3 Place the base of each housing on its sup-
port surface.
4 Place the shaft and Y-bearings into position
in each housing base. Then, place the housing
caps over the bearings († fig. 1) and
install the attachment bolts or nuts.
5 Carefully align both Y-bearing units, using
the shaft. Then, tighten the attachment
bolts or nuts.
6 Align the shaft in the bearing arrangement
axially and – if possible – turn it a few times.
7 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. 2).
8 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. 3).
9 Tighten the grub screw in the eccentric
locking collar of both Y-bearings († fig. 4)
to the tightening torque indicated in table 1
on page 54.
