Dual Rail System for Enclosed Positioning Stage by H2W Technologies

H2W Technologies has designed a low profile, enclosed positioning stage called Dual Rail (DR) stage. The wide footprint of the stage facilitates in mounting a larger and higher force linear motor.

The stage is employed in closed loop positioning applications where high acceleration and speed of heavier loads are required.

The iron core coil assembly of the stage is magnetically attracted to the static magnet assembly, which offers a preload for the bearing system.

The dual parallel linear bearing rails with four linear recirculating ball bushing guides offer a higher load carrying capacity. The low profile of the stage is suitable as the bottom axis (X axis) of a stacked multi-axis system or guarantees a stable platform for the payload.

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

Key Features
