ThermiSeal bellows, which boast an air-, dust-, and light-tight design, provide protection for precision medical equipment, semiconductor equipment, clean room applications, coordinate measuring machines, and inspection and test equipment. They can be used to protect slides, ways, linear actuators, cylinder rods, ball screws, and other actuating members that move through a range of travel. They also can be used to protect scales and vision system components.

The bellows are available in a variety of shapes and sizes in urethane or PVC. They are designed to provide open-to-closed length ratios, which minimize the space they require. For precision applications, they require a minimal amount of force to operate.
