Overview
Whittet-Higgins W-15 Lockwasher
The Whittet-Higgins W series bearing lockwasher is a carbon steel retaining washer used with N / AN / NL series bearing locknuts to secure, lock, and retain bearings and power transmission assemblies on a shaft. An inner tang keys into the shaft keyway while the washer's outer tabs bend into the slots of the mating locknut, delivering accurate angular positioning across numerous locking positions and preventing assembly loosening caused by vibration, shock, and torque.
Effective on both soft and hardened shafts and requiring no special installation tools, it meets and exceeds ANSI / ABMA 8.2-1999. Each lockwasher is manufactured in the USA, is RoHS compliant, and is rated for operating temperatures up to 300°F.

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.
