CARATTERISTICHE: Precision alignment pin that expands to tighten up hole clearance (.10mm minimum expansion on the smallest diameter, up to .25mm minimum expansion on the largest diameter). The pin is an assembly of female split bushes separated by male segments, all on a centre 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.
MISURE: Available in pin diameters from 1/4 to 1", each in a choice of several lengths — see Dimensions page for part numbers.
OPERAZIONE: Tightening the hex nut with a wrench expands the pin diameter to take up slack and secure the pin in place. Hold centre spindle stationary with a hex wrench while tightening.
CONSIDERAZIONE DI DESIGN: Choose a proper pin length such that no split bushes extend beyond the installation hole. All bushes must be contained by the hole in order to exert full pressure and avoid over-expanding the bushes.
MATERIALE: Split bushes, male segments, and spacers > 17-4PH stainless, Rc 40 min, passivated, dry film lube. Centre spindle > 4130 steel, Rc 36-40, cadmium plated, dry film lube. Barrel nut and washer > Carbon steel, cadmium plated, dry film lube. Hex nut > Alloy steel, cadmium plated, with locking element.C13C12C11C10C9C8C5C4 |
