Crossheads
Ariel uses one piece crossheads
with full top and bottom lubrication and with babbitted sliding surfaces,
except for the JGM and JGP which are ductile iron without babbitted surfaces
Full floating alloy steel crosshead
pins are used in Ariel frames; all frames except for the JGM, JGP, and
JGH have bronze crosshead pin bushings. Inadequate rod load reversal can
result in lack of lubrication to the crosshead pin and consequent failure.
Crossheads and crosshead nuts
of varying weight are available to facilitate proper frame balance. Balance crossheads are
available to balance opposite blank throws.
