Sliding Air Jaw Chuck is offered in various configurations.

Press Release Summary:



Developed to grip OD of 9 in. dia helical gears, Pitch Line features pins mounted in loose fitting housing so they can float. Pins pick up pitch diameter, and jaws grip OD of pins. Because pitch is measured over pins, gripping is performed in same manner as measuring. Models include through-hole, high-speed, and quick-change chucks, available in SAE or metric sizes from 3-18 in. (76-457 mm) with accuracies from 0.001-0.00001 in.

Upgraded Applications for Sliding Air Jaw Chuck



Northfield Precision Instrument Corporation is a leader in the design and manufacture of precision workholding air and diaphragm chucks. Northfield manufactures precision air chucks with a guarantee of accuracy within millionths. We have come to be the precision workholding source for air & diaphragm chucks with workholding leadership in accuracy, reliability, repeatability, concentricity, productivity and customer service. Northfield introduces an enhanced "Pitch Line" air chuck.

Northfield Precision has now developed & engineered a "Pitch Line" chuck to grip the O.D. of 9" diameter helical gears. The pins are mounted in a loose fitting housing so they can float. The pins pick up the pitch diameter and the jaws grip the O.D. of the pins. The pitch is measured over pins, so we are gripping the same way they measure. Shown is a Northfield model 1000 (10in. diameter chuck) with two "pin cages" one for a left hand helix and one for a right hand helix. The pin cages are changed out by removing (3) mounting screws

The world's most accurate air and diaphragm chucks for any lathe, boring machine or grinder or VMC. Models include through-hole, high-speed and quick-change chucks.
