Linear Motor Driven Positioning Stages - Stage Comparison Chart

1.	*SR Positioning Stage* Compact, small footprint, open type positioning stage for carrying lighter loads. It is driven by an ironless core, non-cogging 3 phase brushless linear motor and guided by 2 recirculating ball bushing guides on a single linear rail.
2.	*DR Positioning Stage* Low profile, wider footprint, enclosed positioning stage for carrying heavier loads. It is driven by an iron core 3-phase brushless linear motor and guided by 4 recirculating ball-bushing guides on 2 parallel linear rails. The stage is enclosed with side and end covers as well as a set of bellows.
3.	*XR Positioning Stage* 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 enclosed end covers and a set of bellows.
4.	*AB Positioning Stage* High precision, granite base, air bearing positioning stage for high end positioning applications. It is driven by an ironless core, non-cogging 3 phase brushless linear motor and guided by the granite base and 5 flat magnetically preloaded air bearings.
5.	*SC Positioning Stage* Open or enclosed, lead screw or ball screw positioning stages for slow speed, high force, linear servo applications It is driven by either a rotary 3-phase brushless motor or a rotary stepper motor and are guided by 2 sets of parallel cross roller or recirculating bearings. Options include motor mounts, limit switches and linear encoders.
6.	*BL Positioning Stage* Open or enclosed positioning stages for high speed, long stroke, linear servo applications It is driven by either a rotary 3-phase brushless motor or a rotary stepper motor and is guided by 1 set of recirculating bearings. Options include motor mounts, and linear encoders.
7.	*Multi-Axis, Gantry Systems* Multi-axis positioning stage systems can be configured in many different formats. Any combination of H2W Technologies linear positioning stages can be mounted together. Shown in the picture is a 4 axis, dual XZ, Ball screw driven positioning stage, mounted on a granite base with linear encoders on each axis for Dual Loop servo operation.
