The 9061-X Gothic-Arch Linear Translation Stage has stainless-steel construction and thumbscrew locks. This 6.5 mm travel gothic-arch stage with a 25 x 25 mm platform offers the ultimate in stability and rigidity. Gothic-arch bearings offer the smooth motion of ball bearings but high stiffness and repeatability. The unique gothic profile provides four points of contact (rather than two) so that the load and momentum are more evenly distributed. Side-mounted micrometer clamps minimize the overall footprint. These stages are compatible with our goniometers and rotation stages. NOTE: Actuators are not included with these stages. We recommend using our screw sets or our Model 9354 micrometers. For even more precise control, try our Picomotor™ actuator. 8-32 thread.
