flexdrive-8 Features & Benefits

The flexdrive-8 series is an expansion of the product line to a small compact size and the modular design makes it an ideally suited translation module for a larger number of applications requiring precision, reliability and ease of integration. Engineers, system integrators and designer prefer the flexdrive-8 for their superb performance, flexibility to match to the application and assured longevity.

The flexdrive series is a very compact precision stage based on a monolithic high strength aluminum alloy with a 74 x 227 mm envelope and travel range from 250-750 mm.  The payload capability is rated at 70 kg/150 lbs.  The superb positioning performance is supported by square rails with recirculating low noise linear ball bearings and a precision ground ballscrew drive.


This positioning stage is designed as a fine precision machine with selected high-performance components to achieve outstanding positioning performance with extended life expectancy. The stage base is fabricated from a specially selected hardened high-strength aluminum alloy slab, precision machined to extremely close tolerances. In addition, the saddle is equipped with a wear resistant hard-coat anodized protective finish.

The guide system features advanced technology multi-track linear bearings. The four integrally preloaded bearing carriages establish the proper stiffness and achieve constant support geometry for the saddle. This precise and rigid motion platform produces exceptional results in terms of accuracy and motion trajectory, even with high payload.

Custom Options

  • Side Motor Mounting for motor orientation parallel to direction of motion.
