Tri-Grip collet closers are ideal for either horizontal or vertical machining center applications. Their compact design, simplified plumbing (three closers in one body) and patented "accessible-from-the-top" collet locking screw all lead to faster changeouts and infinite collet or part orientation. With a maximum working pressure of 5000 PSI and a drawtube force of 1.1 times the applied pressure, these units can provide ample grip for all your workholding needs. Double acting, fixed-length operation assures maintained height from part to part. Similar in design to most of our single collet closers, these models can be combined in multiple configurations on a fixture by the use of connector bushings that eliminate external plumbing between units. Each Tri-Grip is supplied with a matching collet wrench.

Lexair can supply precision machined standard collets, master collets and pads, emergency collets, serrated collets plus uniquely shaped collets by special order.
