Open-type Single Rail Positioning Stage by H2W Technologies

H2W Technologies offers a compact and open-type positioning stage called SR stage. It is suitable for closed-loop positioning applications where high acceleration and high speed of lighter loads are required.

Since the stage has a low overall weight, it is suitable as a Y axis (top axis) in a multi-axis system. The lower moving mass of the SR positioning stage enables higher accelerations of light payloads.

The ironless core coil assembly of the stage does not have any magnetic attractive force to the stationary magnet assembly. This results in reduced load and improved life of the bearing system. The cable carrier is large enough to enable the passage of payload cables and hoses.

The SR positioning stage includes motors, bearings, encoders, cable carriers, limit switches, bellows and hard stops.

Key Features

The main features of the SR positioning stage are:

  • Small footprint and cross section
  • Lowest weight per unit length
  • High speed
  • High acceleration of light loads.


The applications of the SR positioning stage are:

  • Clean room
  • Vision inspection
  • Parts transfer
  • Pick and place.
