Overview
Whittet-Higgins PPM-68 Lockplate
The Whittet-Higgins PPM-68 is a light-duty PPM-series precision locking plate (metric) that bolts to the face of a matching KM trapezoidal-thread retaining nut to secure and retain bearings and other power-transmission components on a shaft. The arc-segment steel plate is fastened with hex-head bolts and threadlocking compound, locking the assembly against vibration, shock and torque without a keyway and with no special tools required. It is engineered to function with KM-44 and larger locknuts, is made in the USA and is 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.
