Dimensions, Mh-16 – Sheffer MH SERIES User Manual
Page 17
CAUTION
Sheffer trunnion pins are an
integral part of the head (TF
Mount), the cap (TR Mount), or
the ring on the intermediate trun-
nion mount (T). Even though
machining the pins as an integral
part is the strongest, and most
fatigue-resistant method, some
attention should be given to
proper mounting of trunnion
cylinders.
Pillow blocks of ample size and
rigidity should be provided and
should be mounted as close to the
head or cap as possible. Bearing
should be provided for the full
length of the trunnion pin. Pins
are designed for shear loads only,
not bending loads. Lubrication
should be provided to the pins.
All trunnion cylinders need
provision on both ends for pivot-
ing in one direction. Alignment
in the other direction is essential
in order to avoid excessive side
loading. Where two-direction
pivoting is necessary, contact
our distributor for specific
recommendations.
Selection of piston rod diameter
can be determined by consulting
separate Engineering Brochure.
See Engineering Brochure for
information concerning the appli-
cation of long stroke cylinders.
See separate Accessories Brochure
for additional data on cylinder
mounting.
