Lightweight Linear Motor Axes


WEISS North America, Inc. has introduced its latest in uncompromising, highly dynamic drive technology for your basic axis−the lightweight, aluminum profile-based HG 12 and HG 25 linear motor axes. Notably, the new closed linear axes based on aluminum profile design overtakes traditional belt drive and spindle drive technology in reducing costs while achieving a far more precise axis and definitive edge in compactness. An extension of their acclaimed HN series, the highly integrated and ready-for-installation HG series is also engineered with a unique guide profile cover that is made of machined aluminium−providing optimal protection for applications that experience external contamination influences and extends service life.

The compact and precise ball-type linear guides feature an absolute measuring system as well as automatic lubrication. The HG series is available in two different axis sizes – HG 25 with peak force of 180 N, and HG 12 with peak force of 110 N. Both versions impress with their smooth movements and maximum dynamics. The lightweight, aluminum profile-based HG axes can also be used in areas where cost factors have typically made conventional drives the standard choice in the past. Specifically, they are designed for lighter load applications−with the HG 25 & HG 12 offering 10kg and 5kg maximum load capacities respectively. Ultimately, they deliver high-speed and accuracy at a lower cost−with a maximum acceleration of 40 m/s2 and a maximum speed of 4 m/s. Typical small parts assembly applications that would benefit from the HG series include: electronics, flat panel displays, semiconductors, machine tools, material handling, medical, packaging, etc.
