HDS75 Stage

Heavy Duty Linear-Guide Stage

The HDS75 linear guide stages are ruggedized, budget-friendly positioners designed for heavy loads. They can position high masses, high moment loads, and variable center-of-gravity loads to repeatabilities as tight as 10 µm. The HDS75 stages are both accurate and rigid, courtesy of an extruded aluminum U-channel base and high-load linear guides. Because the screws are supported at both ends, they are under tension, increasing critical speed. Stages can be combined in XY configurations without the need for an adapter bracket; Z-axis stages do require a support bracket.

Because we build the stages in-house, users have many options, starting with a choice of photo/proximity sensors. Other options include choice of leads, motor mounts, cover types, and more, including a hand-cranked version. Like our other products, the HDS75 stage can be customized to serve particular needs.
