W721 – W723
All larger robots including the W721 models are designed with moveable kick stroke beam which is guided directly in the main carriage. The reduced moveable mass allows high acceleration and deceleration for extremely short cycle times.

• W721: The vertical arm is a rigid aluminum extrusion and guided in heavy-duty linear bearings. Driven by servomotor via belt to allow high speeds and short removal times.
   
• W721 UHS: Reinforced aluminum extrusion with 2 linear rails and powerful servo drive for highest accelerations and speeds. The top performance robot for the automation of thin wall injection molded parts for cycle times below 6 seconds. Configuration for reduced gripper and parts weight up to 5 kg (11 lbs).
   
• W723: Telescopic Vertical Axis: The gripper is arranged in front of the telescopic arm and allows a very short telescopic tube. For minimum overall height and fast movements.

W731 – W732
The larger rugged main steel beam allows a wider distance between the main bearings and therefore longer kick-strokes up to 900 mm (reach 1190 mm) and longer vertical strokes up to 1600 mm.

• W731: Same vertical arm design as W721 but for vertical strokes up to 1400mm. Due to the high operating speeds of the vertical arm and handling weights up to 10 kg (22 lbs), the W731 is one of our bestsellers for IMM up to 500 tons locking force.
   
• W732: The vertical arm is a rigid aluminum extrusion with two high- load linear bearings and a maximum length of 1.600 mm. For payloads up to 20 kg (44 lbs) with high torque C-axis rotation for placing, the W732 is a popular robot for insert jobs.
