Overview
Whittet-Higgins W-030 Lockwasher for small profile locknut
The Whittet-Higgins W-030 is a small-profile bearing lockwasher from the W-000 series, manufactured from carbon steel to ANSI/ABMA 8.2-1999 specifications. It is matched with N-000 series locknuts to secure, lock, and retain bearings and power transmission assemblies on a shaft. An inner tongue keys the washer to the shaft while its numerous external tabs bend into the slots of the mating locknut, providing accurate angular positioning and preventing the assembly from loosening under vibration, shock, and torque.
Its reduced diameter and thickness suit limited-space and lighter axial-loading applications, and it installs without special tools on both soft and hardened shafts. Rated for a maximum operating temperature of 300°F, this is one of the most cost-efficient light-duty bearing lockwasher lines available. Manufactured in the USA and RoHS compliant.

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.
