Overview
Whittet-Higgins N-032 Locknut
The Whittet-Higgins N-032 is a small-profile bearing locknut that threads onto a shaft to secure, lock, and retain bearings and power-transmission assemblies under lighter axial loads. Its reduced outside diameter and width suit limited-space installations, and it is matched with a W-000 series lockwasher whose tab engages the nut to provide accurate angular positioning across numerous locking positions while preventing loosening from vibration, shock, and torque. Sizes N-048 and larger include a PP locking plate, and no special tools are required for installation on soft or hardened shafts. Manufactured from carbon steel in the USA and RoHS compliant, it meets and exceeds ANSI/ABMA 8.2-1999.

About the brand
About Whittet-Higgins
Bearing locknuts, lockwashers and retaining devices from Rhode Island since 1914.
Henry Whittet and John Higgins founded the Whittet-Higgins Manufacturing Company in 1914 in the basement of a mill on Congress Avenue in Providence, Rhode Island, making super-precision bearing retaining components and machined parts for local machine builders such as Brown & Sharpe.
In 1967 the company was sold to a young mechanical engineer, and in 1969 it moved to 33 Higginson Avenue in Central Falls, Rhode Island, where it still makes its products. Its first line of 66 locknuts and lockwashers has grown to more than 4,300 standard parts, made on robotic CNC systems.
Besides the standard N/AN and KM locknuts with W and MB lockwashers, Whittet-Higgins makes its own self-locking designs: Bearhug prevailing-torque locknuts, Bearlok, Shoelok and Tangentlok clamping locknuts, clampnuts and splitnuts, plus adapter sets, clamp collars and installation tools. The company is family owned and operated.
