Linear-Motion Systems With Protective Bellows

Two preassembled linear-motion systems from PIC Design, Middlebury, Conn., have protective bellows made of polyurethane-coated nylon. The bellows protect bearings and leadscrews from harmful debris. Operating temperatures range from –65 to 250°F. System 9B, a Twin Track system, is recommended for vertical applications. It has a 0.75-in. suspended shaft and a 0.5-in.-diameter leadscrew. Five travel lengths from 2.9 to 15.4 in. are available. A second Twin Track system, called System 10B, incorporates supported rails that are integral to the base plate. Ten travel lengths ranging from 3.5 to 29.6 in. are available. Typical dynamic-load capacity is 300 lb for both systems.
