Callout Component Description
1 Anti-Rotate Tabs These tabs on the swivel eye restrict the twisting motion of the swivel
assembly.
2 Swivel eye The base swivel eye can be mounted to the base of the actuator, while
the rod swivel eye is designed for mounting to a load cell or the piston
rod of an actuator. The swivel eye contains the spherical bearing.
3 Swivel jaw The swivel jaws secure the swivel to the reaction mass. It features two
sides joined by a pin that passes through the spherical bearing.
4 Spherical bearing The spherical bearing allows the swivel eye to tilt and rotate through a
wide range of motion.
5 Clamping bolt
(adjustable swivels only) Depending on the size of the swivel, a single bolt or a Superbolt
Torquenut clamps the swivel eye.
6 Hardened washer
(adjustable swivels only) A washer under the clamping bolt provides a hardened surface to
tighten against, preventing deformation of the swivel eye.
7 Adjuster
(adjustable swivels only) Available with Series 249 swivels, the adjuster is a threaded sleeve that
screws into and out of the swivel eye to act as a variable shim when
adjusting swivel backlash. Proper adjustment eliminates backlash and
allows the clamping bolt or torque nut to be tightened adequately
without causing excessive friction in the spherical bearing.
