Crossed roller linear positioning stage
max. 12 " H2W Technologies, Inc

The XR Positioning Stage is a compact, small cross section open or enclosed positioning stage for short stroke linear servo applications (up to 12 inch stroke). It is driven by either an iron core or ironless core 3-phase brushless linear motor and guided by 2 sets of parallel cross roller bearings. The stage can be with enclosed end covers and a set of bellows.

For higher force applications an iron core brushless linear motor is used. In this case the moving coil assembly is magnetically attracted to the stationary magnet assembly, which provides a preload for the crossed roller bearing system. For lower force applications and where velocity ripple is a concern due to cogging, an ironless core brushless linear motor is used

The dual parallel rail sets offer excellent load carrying capability.

The wide, low profile of the stage ensures a stable platform for the payload or as the bottom axis (X axis) of a stacked multi-axis system.

The small overall package size makes the XR stage ideal as a Y or Z axis for short stroke positioning applications.

The XR stage comes standard without bellows (folded way covers) , but they can be added as an option.

A cable carrier is not supplied with this stage because of the short stroke, but can be added as an option, if desired.
