Swivel makes light work of heavy loads

Machine builders face a vexing problem when there’s a need to rotate large or unwieldy products in assembly, handling, and packaging applications. Engineers often must select and size an electric motor; evaluate direct, belt, or gear drives; find bearings that can handle the loads and give long life; and assemble the entire package and fit it into often-limited space.

A better option may be a guided pneumatic swivel module that provides a versatile, rotating drive for large and hard-to-handle loads.

Air logic upgrades composites manufacturing

Molded composite parts are commonplace in products ranging from boat hulls and hot tubs to storage tanks and wind turbines. However, regulatory pressures are impacting the composites manufacturing process, and that has producers turning to pneumatic controls.

All-in-one actuator upgrades extrusion press

Metal extrusion may seem like an old-style industrial operation, but Presezzi Extrusion SpA, headquartered near Milan, Italy, has elevated it to a high-tech enterprise. The company designs, builds, and commissions presses for extruding aluminum, steel, copper, and brass.
