Overview
Whittet-Higgins MBS-40 Lockwasher
The Whittet-Higgins MBS series is a stainless steel metric bearing lockwasher used with KMS series locknuts to secure, lock, and retain bearings and power transmission assemblies on a shaft. An inner tang seats in the shaft keyway while an outer tab is bent into a slot of the mating KMS locknut, providing accurate angular positioning across numerous locking positions and preventing the assembly from loosening due to vibration, shock, and torque.
Corrosion-resistant stainless construction makes the MBS line well suited to wet and chemically aggressive service, and it installs without special tools on both soft and hardened shafts. Promoted as the most cost-efficient metric bearing lockwasher line available, the MBS series meets and exceeds ISO 2982-2:2013(E), is RoHS compliant, and is manufactured in the USA.

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.
