Ultimate Whittet Higgins Cnb-32 Clamp Nut Series [PGAqvHYJ]

This series of CLAMP NUTS has the bearing threads specified to the AFBMA/ANSI standards, fits, and tolerances thus are fully interchangeable with the retaining devices generally used in bearing and other power transmission assemblies. These threads are in accordance with the American National Form of the National Standard Class 3 with thread length based on a 45° chamfer as specified in the Screw Thread Standards as set forth in the Federal Services Handbook H-28-1957.

The bearing face - the side with the clearance relief above the face diameter - is machined square to the axis of the pitch diameter of the threads whereby the runout for one revolution has a total indicator reading variance no greater than: .002 for sizes 00 to 14, .004 for sizes 15 to 40.

As with all precision retaining devices, care must be taken during assembly to assure premium performance. Please open and review our installation instructions for proper technique and best results.
