Overview
Whittet-Higgins CC-28S Clamp collar
The Whittet-Higgins CC series is a one-piece mechanically self-locking clamp collar that grips the shaft when its integral socket-head cap screw is tightened, drawing the collar bore tight around the shaft. It delivers infinite axial adjustment and secure positioning of bearings and other power transmission components, holding firmly against vibration, shock, and torque without cutting or repairing a shaft keyway.
The one-piece design provides more secure locking than set-screw collars and is effective on both soft and hardened shafts. Standard collars are black-oxide-coated carbon steel with a hardened alloy clamp screw, rated to 300°F, and are also offered in stainless steel and aluminum alloy.

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.
