This is a Design Components linear motorized stage consisting of two linears arranged in an XY configuration. Each linear motion slide is 15 x 10 inches (base and top plate same). There is a mounting plate for NEMA 23 motors that is proud of the base long dimension by 0.720�. The flex coupling is present on both stages, but both motors are absent. Each stage has a 6-inch range of motion and runs on cross-roller bearings.

Each linear has an end-stop detector system fixed to one side with adjustable limit plates. All four plates are present, and the cable for both axes terminates in a single connector (see third photo). Each linear stage is 3� tall, so the pair is 6 inches tall. The upper slide is pin-registered to the lower slide, and may be removed if desired. Model number of the stage is DC-1010R Serial number is M1-11. The complete stage weighs close to 77 pounds without motors.

The stage appears to be in excellent condition. Both linears were run to the limits of their excursions without any problems. The lead screws appears to be a ball-screw type and very little force was required to actuate the stage

I was unable to find out any of the specifications on this stage, but it certainly appears that it is meant to support hundreds of pounds.

This is a Teradyne compound XY linear translation stage with 4 inches of motion on each axis. The stage includes a pair of stepper motors, but there is no nomenclature on the motors, and the cables to the drive electronics have been severed. There are no knobs for manual operation. There are also two small oil reservoir covers, but I cannot see how the reservoir communicates with any of the moving elements, although there was definitely an oil residue on both the leadscrew and on the rod bearings, so it must function.

This stage probably dates from the late 1960�s but is in very fine condition and has some very interesting construction features that are quite unique. The fixed base of each axis consists of an aluminum extrusion the cross-section of which is shaped rather like a capital Omega. On the vertical section of both sides of the base a groove has been milled into which are set paired half-inch precision ground hardened bearing rods. The moving element (the table) wraps around the outside of the rods on each side. On the leading and trailing edges of each side of the table are half-cylindrical recirculating bearing cages. The table carriage is constructed in a manner that allows drawing the raceways against the rods using just two cap screws on the underside of the table. It is therefore very easy to preload the bearings and completely eliminate all play merely by setting two screws.

The leadscrew is supported on either end by very large ball-bearing races, and there is a flex coupling to the motor attached to the end of the stage. The motors on both axes are unmarked, and there is a terminal circuit board inside the enclosure next to the motors on both axes. Connections from the motor and also from a pair of limit switches are routed into the enclosure, as is the remnant of a truncated cable. My recommendation would be to replace the drive motors with new motors since none of the motor characteristics are known. It looks like an exchange could be very easily accomplished.

The two axes are easily separated after removing four mounting screws. I have done so for most of the photographs. Both axes are of similar construction, although the lower stage has three alignment pins set into the table platform (easily removed to produce a flat surface). Dimensions of the individual axis stages are as follows:.

Stage Base Length = 9.375 inches (not including end caps and motor housing)
Stage Base Width = 3.750 inches
Overall Length of Base = 14.25 inches (includes motor and bearing housing)
Overall Width of Table Carriage = 4.75 inches
Precision Ground Table Length = 5 inches
Table Width = 3.5 inches
Height of Stage = 2.375 inches (single axis only)
Overall Height of Compound Stage = 4.75 inches

The stage is in very fine condition � mechanically they look mint, but there is a bit of paint loss on the sides of the two carriages (very minor). I do not know the load-bearing capability of the stage, but it is certainly exceedingly robust.
