The Dual 180˚ carrier requires its own proprietary tube supports and foot mounts. See dimensional information. Breakaway torque will also increase when using the Auxiliary carrier or the Dual 180˚ carrier options. When ordering, determine working stroke and enter this value into the configuration string. Overall actuator length will automatically be calculated.

Deflection Considerations: In applications where substantial Mx or My moments come into play, deflection of the cylinder tube, carrier and supports must be considered. The deflection factors shown in the Load Deflection charts on the following page are based on cylinder mounted with tube supports at minimum recommended spacing. If more rigidity is desired, refer to the Auxiliary or Dual Carrier options.

*Loads shown in table are at minimum “D” dimension, for ratings with longer “D” dimension see graphs in B3 Catalog 3600-4176

Contact Tolomatic for higher accuracy and lower backlash options.
*For Acme screws, maximum thrust is the maximum continuous dynamic thrust subject to Thrust x Velocity limitation.
For ball screws, maximum thrust reflects 90% reliability for 25 million linear millimeters of travel.

Dual 180 Carrier

¹The listed values relating to straightness/flatness are intended for reference purposes only, and not as an engineering standard of absolute tolerance for a given actuator. Appropriate installation is the single most important factor in reducing such deviation, so good engineering practices such as measurement, mapping, etc. must be employed in applications with stringent straightness/flatness requirements.

²Heat generated by the motor and drive should be taken into consideration as well as linear velocity and work cycle time. For applications that require operation outside of the recommended temperature range, contact the factory.

³Protected against ingress of solid particles greater than .039 in (1mm) and splashing water.

* “L” is maximum distance between supports— See the support recommendation graph in B3 Catalog 3600-4176.

LARGE FRAME MOTORS AND SMALLER SIZE ACTUATORS: Cantilevered motors need to be supported, if subjected to continuous rapid reversing duty and/or under dynamic conditions.
