Overview
Whittet-Higgins MBB-044 Lockwasher
The Whittet-Higgins MBB-044 is a heavy-duty metric bearing/shaft lockwasher — a thicker version of the standard MB series engineered for higher-load bearing and power-transmission shaft assemblies. It seats between the bearing and a KM, KML or KMM metric locknut, with an internal key that engages the shaft keyway and external tangs that bend into the locknut slots to lock the assembly against vibration, shock and torque. Manufactured in carbon steel to ISO 2982-2:2013(E).

- Pairs with Whittet-Higgins KM, KML and KMM metric locknuts
- Internal key engages the shaft keyway; external tangs bend into the locknut slots to prevent loosening

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.
