The highest stress point in a wire wrap wound clutch is where the ends are turned ninety degrees to the normal wrap of the wire. When the HELI-CAL® Flexure is "machined" we not only don't bend the coil ninety degrees, but we are able to leave additional material in the radius of the stem which increases the strength and reduces the stress level even more. Helical was again able to solve a customer's application with a reliable HELI-CAL Flexure that also saved them production time in assembling their complete product.
