The numbers in these dimensional drawings and specification tables represent performance parameters for our standardized models. We can always customize a model more specifically to your application.
Additionally – the Max Speed ratings shown below are for applications with 1 meter stroke applications or less, please contact our engineering group to confirm critical rotational speeds at longer lengths. The specifications shown in our tables represent the actuators’ capabilities. Final actuator performance will always vary pending motor and gearing selection.
The standard lead error for our ball screws is +/- 52um/300mm. The standard lead error for our trapezoid screws is +/- 75um/300mm.
Definitions:
Mz-Yaw – certain application stresses might turn the actuator body right or left
My-Pitch – certain application stresses might pull / push the actuator nose upwards or downwards
Mx-Roll – certain application stresses might roll the actuator body right or left
We invite you to review the attached pdf’s and engineering resource links for each model, the engineering link directs customers to our 3D modeling and more detailed performance data. Please contact us anytime for additional information or assistance.

Common accessories - Fastening Hardware:
The Paletti hardware has been custom engineered specifically for our products, and is quick and simple to use. Our central fasteners are an excellent choice for most corner assembly needs. Our T-Nuts are commonly used in some corner assembly or other assembly needs. Particularly, the push-in T-Nuts are very useful and also offer the benefit of being installed and positioned after the rest of the assembly has been completed and with the option for mounting the assembly to other surfaces.
