Product Information

Expanding Pins (Hex Head) Part # CL-4-EXPH-2.00 Carr Lane Mfg.®

Expanding Pins are precision alignment pins that expand slightly to tighten up hole clearance. This pin is an assembly of female split bushings separated by male segments, all on a center spindle, that expands when drawn together. This assembly provides excellent shear strength, comparable to a solid pin. Expanding Pins can be installed in through holes or blind holes. Available in standard pin diameters from 1/4 to 3/4", each in a choice of several lengths. Made in USA.

Operation

Expanding Pins are an assembly of female split bushings separated by male segments, all on a center spindle, that expands when drawn together. Tightening the hex nut with a wrench expands the pin diameter to take up slack and secure the pin in place. Hold center spindle stationary with a hex wrench while tightening.

Design Considerations

Choose a proper pin length such that no split bushings extend beyond the installation hole. All bushings must be contained by the hole in order to exert full pressure and avoid over-expanding the bushings.

Material

Split bushings, male segments, and spacers > 17-4PH stainless, 17-4PH stainless, Rc 40 min, passivated, dry film lube. Center spindle > Rc 36-40, passivated, dry film lube. Barrel nut and washer > 17-4PH stainless, passivated, dry film lube. Hex nut > 17-4PH stainless, with locking element. RoHS compliant.
