H2W Technologies released its the Four-Axis Gantry (YY’ZZ’) is a positioning stage consisting of two SRS-007-03-006-01 brushless linear motor stages; each vertically mounted to two independently moving horizontal linear axis. Each horizontal linear axis uses a BLDM-D04 H2W brushless linear motor to generate a continuous/peak force of 16.5 lbs. [73.6 N]/49.0 lbs. [220 N] with each moving table capable of a total stroke length of 47.1 in [1196 mm].

Each moving table has an independent non-contact 1.0-micron resolution encoder head reading a single encoder scale and is guided by a rigid recirculating ball linear bearing block sharing a single linear bearing rail. Each vertical axis (SRS-007-03-006-01) uses a BLDM-B04 H2W brushless linear motor to generate a continuous/peak force of 6.2 lbs. [27.8 N]/18.7 lbs. [83.3 N] with a total stroke length of 7.0 in [177.8 mm]. The entire stage is assembled on a single piece of aluminum extrusion, thus reducing the overall size and weight of the system.
