Overview
Whittet-Higgins NSH-36 Locknut
The Whittet-Higgins Shoelok (NSH series, inch thread) is a mechanical self-locking bearing retaining nut that threads onto a shaft or spindle to position, preload, and secure bearings and other power-transmission components. It locks by means of tangential (X-axis) socket cap screws that, when torqued in a bolt-circle pattern, drive internally threaded hardened shoes radially inward against the shaft threads, producing uniform 360-degree clamping to the center of the shaft without damaging the threads.
Because adjustment and locking are accessed from the side of the nut, the Shoelok provides infinite adjustment and preloading capability and installs faster than a traditional locknut-and-lockwasher arrangement while eliminating the need to cut or repair a shaft keyway. Built entirely from hardened alloy and manufactured in the USA, it meets and exceeds the specifications of 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.
