Rigid support for
swivel mounts
The swivel base assembly is not designed to rigidly support an actuator for
vertical operation. In general, actuators that require rigid support are equipped
with a pedestal base accessory. Should it become necessary to rigidly support an
actuator with a swivel base assembly, contact MTS Systems Corporation for rigid
support recommendations.
Mounting a Swivel
All models of the Series 249 Swivels can be mounted with four socket head bolts.
The mounting bolt size is determined by the model number. See the following
table for the recommended mounting bolt size, torque, grade, and mounting bore
thickness.
