Cam Handle Expanding Pins
Supplier: Carr Lane Mfg Co
FEATURES: Precision alignment pin that expands to tighten up hole
clearance (.004" minimum expansion on the smallest diameter, up to .010"
minimum expansion on the largest diameter). The 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. Made in USA.
SIZES: Available in the following pin diameters, each in a choice of several lengths — see Dimensions page for part numbers:
Moving the cam handle through its full travel expands the pin diameter
to take up slack and secure the pin in place. If additional adjustment
is required to achieve desired retention force, loosen the setscrew in
the center of the barrel nut, turn the center spindle to achieve a tight
fit, then retighten the setscrew.
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.
