These stages have a width of 250 mm as described in the drawing below. They can support heavy loads, still provide precision positioning. Resolution of 0.02 mm is possible by a combination of linear scale by the side of the stage and circular graduations on the knob. Re-circulating type ball bearing guide ways ensure play-less and stick-slip free linear positioning. XY and XYZ configurations are possible by the use of accessories like angle brackets and base plates. There are tapped holes on top and counter bored holes on base for the ease of mounting. Dust protective bellows are optional.
