Series 249 Rod Swivel Functional Description
The Series 249 Swivels are used for testing purposes where swivel movement
with minimum backlash is required. They are particularly suited for the demands
of closed-loop servohydraulic testing applications.
The swivels can be mounted to a linear hydraulic actuator, load cell, or
mechanical linkage. A reaction mass, bedplate, or structural component can be
attached to a mounted swivel.
For structural testing applications, a linear actuator equipped with both a swivel
base and swivel rod end provides pivotal freedom at both ends of the actuator (as
shown to the right).
The swivels are available in six different models with force ratings from 25 to
1000 kN (5.5 to 220 kip).
Depending on the size of the swivel, one of two different types of bolts is used to
clamp the swivel eye.
• Models 249.12/.20/.23, and .32 use a single bolt.
• The larger Models 249.41/.42, and .51, which require greater clamping
forces, use a Superbolt Torquenut.
