This type of stages has their drive mechanism by the side of the stage. This mechanism reduces overall length of the stage. The stage provides traverse ranging from 50 mm to 150 mm. There are mounting holes on top as well as bottom surface of the stage. The drive is given by either ball screws or lead screws depending on application. Crossed roller based linear guides are used for achieving precision linear motion. The guide ways are factory preloaded to eliminate play and wobble. Coefficient of friction is less than 0.003. Standard stages are constructed in aluminum alloy and finished by black anodizing.
