Abstract
A chuck including a body with a nose section defining an axial bore formed therein, a plurality of jaws movably disposed with respect to the body, and a sleeve rotatably mounted about the body so that rotation of the sleeve moves the jaws relative to the axial bore. A bearing has a first race, a second race, and at least one bearing element disposed therebetween, one of the first race and the second race defining a ratchet and the other defining a pawl biased toward the ratchet. A biasing element is disposed between the pawl and the sleeve. The biasing element exerts a biasing force on the pawl toward the ratchet and the ratchet and the pawl prevent the second race from rotating in the opening direction with respect to the first race when engaged.
