Linear actuators are not meant to be side loaded. The use of rod ends is encouraged to avoid these type of loads. This product is shipped unassembled. Please see the assembly instructions for how to put this product together. We chose to ship this product unassembled in order to be able to offer it at a low price.
Note: The CIM Motor (am-0255) and the DART Sensor Kit (am-3077a) are NOT included in this product, and need to be purchased separately.
**NEW** Improvements, as of November, 2016:
We've listened to customer feedback and responded with these improvements.
- Rod Cap is now zinc-plated steel instead of aluminum.
- The 5/16-24 female mounting hole at the end of the actuator is much stronger.
- 3/16" Shoulder Screw holding on the 14T gear on the linear drive has much longer threads.
- AndyMark is assembling the entire linear module (this is why we raised the price by $14)
- 2.5:1 204lbf at 5.33 in/s
- 2:1 163.4 lbf at 6.67in/s*
- 1:1 81.7 lbf at 13.3 in/s*
- 10-turn potentiometer is included, sensing the turns of the leadscrew
- A 14 tooth gear on the lead screw turns a 96 tooth gear on the potentiometer for a 6.85:1 ratio
- The potentiometer will turn 4.4 times during a 6 inch travel
- An optional hall effect sensor kit (am-3077a) is available (but not included) as an add on
Linear actuators are not meant to be side loaded. The use of rod ends is encouraged to avoid these type of loads. Each end is tapped for a 5/16"-24 thread to accept common rod end sizes.
The DART was designed to achieve equivalent forces of a 2" bore pneumatic cylinder at 60 psi and to be used with a CIM motor fused at 40 amps. While it's possible to exceed these values you may see decreased life in the various ware components.
It is recommended to run this actuator with hall effect and/or current protection as it is possible to stall or "stick" the lead screws when stalled against a hard stop at both ends of travel. It's recommended to use the the hall effect switches to limit travel of the actuator from the end stops. When using faster ratios it may be possible to overrun the limits slightly and programming methods may require ease into stroke ends. If you are not able to program these functions we recommend using a Talon SRX which has on-board switch monitoring and current protection.
- Diameter: 0.50 in.
- Efficiency: 53%
- Material: 4140 Steel

This is a strong fast actuator that is a little challenging to put together
DART, 6" Actuator Kit (am-3076a)
The DART actuator shipped on time, and is a quality product. Exactly what we needed for this year's challenge.
