General Description of Spherical Guide Bushing Set
FOR INCLINED PIN
q For Operation

The spherical guide bushing set forinclined pin reduces machining andassembly hours for the core blockejection mechanism.
It absorbs excessive load applied
to the inclined pin and reduces
breaking of the pin.

pin is removed and inserted. In this case,the urethane stopper is available toreduce rotation of the inner wheel.
The urethane stopper is designed to be
screwed in from the outer wheel. Do notscrew it in without the inclined pin.

Relie

f hole1) Concentrated load occurs at the bearingend (Fig.q) and ejection resistanceincreases.
2) Excessive bending moment (Fig. w) is
generated in ejection.

As shown in the figure in the left, loadfrom q and w is absorbed and reducedby rotation of the spherical guidebushing. Problem of breaking is limited.

Breaking3) A large number of hours is required for
adjustment due to machining error. (Fig.eand each guide hole)q After locating the core block, inclined pin
and slide unit and adjusting the inclined
pin length, tighten the mounting boltof the guide bushing set temporarily
and move the plate several times foralignment with the inclined pin.
Then, tighten the mounting bolt finallyand machine the dowel pin hole.

e Mount the bushing so that the longitudinalside of the guide bushing may match theinclined direction of the inclination pin.

e The inner wheel of the guide bushing
set has oilless bearing. Lubrication in
operation is not required.
For initial operation or assembly after
maintenance, apply grease to the inner
wheel of the bushing or the inclined pin.
