Linear Actuators with Optional Position Feedback
The  Linear Actuator family consists of modular components made up of end plates, carriage plates,  carriage top plates, motor mounts, flexible couplers, steel shafts, lead screws and thrust nuts.  All the mounting and end plates are made from T6061 Aluminum.  Shafts are steel and available in various lengths and diameters.  These components can be mixed to create linear actuators of different lengths and load capacities.  Actuators are available assembled or as individual components.  

Linear actuators are available in different lengths, shaft diameters and widths.  Bigger shaft diameters coupled with shorter lengths allow stiffer configurations. 

The modular nature of the design allows simple assembly and replacement.  Low cost threaded rod for the lead screw keeps the cost low and is perfectly suited for many applications.  Lead screws are available in various diameters for lightly loaded X and Y axis while  larger diameters are used for  heavier Z axis.  Shaft and lead screw material can be source locally, cut to length and installed.

Opposing thrust nuts mounted in the carriage end plates maintain tension on the lead screw with minimal backlash. Lock nuts keep the bearings in place during operation.  Teflon or roller slide bearings can be used in the carriage assembly.  The carriage top plate is precision fit to the two carriage end plates with a center depression and tapped mounting holes that accept adapter plates to mount another Linear Actuator.  A special nut on either side of the lead screw eliminates the need for lead screw end preparation.

Adapter plates allow two Linear Actuators to be precision mounted in various orientations to suit a wide variety of applications.  Grooves in the carriage plate fit into ridges in the adapter plates ensuring a precise 90 degree mount.  A second linear actuator can be mounted horizontally or at right angles to the carriage plate.  Adapter plates enable rapid assembly of Cartesian robots or mill configurations.

A new axis can also be mounted vertically.  The grooves ensure the axis line up exactly 90 degrees.

By integrating a magnetic strip and sensor into the bottom of the LA real time position feedback of position becomes possible.  This feature can be added or not added - it's an option.

By making the linear actuator design modular it becomes possible to make LA's of different sizes to match the application.
