New HepcoMotion® PSD80 Profile Screw Driven Unit Now Available from Bishop-Wisecarver

Exceptionally versatile linear actuator is ideal for lighter load applications.

Pittsburg, CA - Bishop-Wisecarver Corporation, manufacturer of the original DualVee guide wheel and industry leader in guided motion technology, announces the availability of the new HepcoMotion® PSD80 Profile Screw Driven Linear Actuator with high efficiency Herculane® wheel technology. Designed to complement the established PSD120 ball screw actuator, PSD80 was primarily developed around the need for a cost effective Z axis solution in lighter load applications such as pick and place and assembly operations.

Housed on a high strength aluminum beam and fitted with a stainless steel sealing band, the PSD80 uses Herculane wheels mounted to an adjustable carriage, offering long life and no re-lubrication. Single or multiple carriages on a unit are possible and can handle loads to 500N. A stainless steel lead screw provides actuation with pitch ranges of 4, 15, 25 and 70mm. The 25mm lead is particularly useful in Z axis applications, while the 70mm screw pitch satisfies the higher speed pick and place requirements and allows speeds up to 1 m/s and thrust loads to 300N. The lead screw is available in right and left handed threads and offers smooth, strong and precise actuation. A ball screw can be supplied for applications that require greater positioning accuracy.

PSD80 is supplied as a closed or open format dependent upon the application being subject to the ingress of dirt. The closed unit is rugged, tolerant of debris, and offers many mounting options while the open version is a lower cost solution that is compact, light, and has low friction. Where two units are to be used in parallel, a "slave axis" without the driving screw can be specified for both closed and open units. Adding to its flexibility, the PSD80 is available in a completely corrosion resistant version, as well as a double acting version for applications that require symmetrical movement from opposing carriages.
