Linear actuators CAT 21B The modular design concept of the CAT 21 actuator makes it easy to interchange critical components such as Motors, Screws, attachments etc. to build a custom actuator easily and cost effectively from a large inventory of standard parts. This flexibility makes it suitable for a virtually infinite number of product combinations to an equally infinite number of applications. This compact, yet robust, CAT 21 actuator is especially ideal for space limited applications. The maintenance-free design makes it cost effective while offering high operating reliability. CAT 21 actuators feature large dynamic load capacities with low energy consumption while operating silently and efficiently over their full load range. Benefits • Compact design (efficient and cost effective) • Ball screw technology • High operating reliability • Low energy consumption • Lubricated for service life • Corrosion resistant • Silent operation • Range of front and rear attachments

Options
Standard options Right or left handed motor orientation. With or without motor cover. Customer options (available on request) Encoder and feedback options Adjustable or fixed position Limit switches Special front and rear attachments Special colors and gear house engravings Special wiring and Connectors Special lead screws and nut combinations

If in any application there is a risk that the actuator mechanically runs into the end stop, we recommend that you use the limit switch option.
