Introduction
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 above).
The swivels are available with force ratings from 25 to 1550 kN (5.5 to 350 kip).
Models are available with or without backlash adjustment in all force ratings.
Depending on the size of the swivel, one of two different types of bolts is used to
clamp the swivel eye.
• 249 Swivels smaller than 500 kN (110 kip) ratings have a single bolt.
• 249 swivels 500 kN (110 kip) and up, which require greater clamping
forces, use a Superbolt Torquenut.
