Overview
Whittet-Higgins BMM-22 Bearhug retaining nut hardened alloy
The Whittet-Higgins BEARHUG is a prevailing torque, self-locking bearing locknut machined from hardened alloy for high axial loading capacity. A heat-stabilized polymer locking ring engages the shaft threads to keep the assembly from loosening under vibration, shock, and torque, while permitting infinite adjustment and preloading without damaging the threads or requiring a keyway. It threads directly onto metric shafts and replaces the traditional locknut-and-lockwasher combination for faster, balanced installation in higher-speed assemblies. The BEARHUG meets and exceeds the specifications of ISO 2982-2:2013(E).

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.

FAQ
BMM-22 questions & answers
What size is the Whittet-Higgins BMM-22?
The Whittet-Higgins BMM-22 is a Bearhug self-locking locknut. Thread: M110 × 2 (pitch 2 mm). Outside diameter: 145.0 mm (5.709 in). Face diameter: 133.0 mm (5.236 in). Width: 22.0 mm (0.866 in). These are Whittet-Higgins' maximum sizes from its spec sheet.
What thread does the BMM-22 fit?
The Whittet-Higgins BMM-22 fits a M110 × 2 right-hand shaft thread (pitch 2 mm).
Does the BMM-22 need a lockwasher?
No. The Whittet-Higgins BMM-22 locks itself: a heat-stabilized polymer locking ring grips the shaft thread (prevailing torque). It needs no lockwasher and no keyway in the shaft.
What tool installs the BMM-22?
Whittet-Higgins' BASM-22 assembly socket: it holds all four spanner slots and takes a square-drive ratchet or torque wrench. To clean or repair the shaft thread first, Whittet-Higgins makes the RTDM-22 rethreading die.
What temperature can the BMM-22 take?
Whittet-Higgins rates the Bearhug BMM series (high strength) for up to 160 °F (71 °C).
What is the BMM-22 made of?
Locknut: hardened alloy; Locking ring: heat-stabilized polymer.
Is there a drawing or CAD model of the BMM-22?
Yes. Whittet-Higgins publishes a part print (PDF) and a 3D CAD model (STEP) for the BMM-22. The drawing on this page is made from the same catalog dimensions.
How do I install the BMM-22?
Follow Whittet-Higgins' assembly instructions for this part (PDF). In short: lubricate the shaft thread, turn the Bearhug on with its smaller bevel face toward the bearing, and tighten it with a spanner wrench or the BASM-22 assembly socket to the bearing maker's preload. Do not use it to push parts along the shaft.
Is this a genuine Whittet-Higgins locknut?
Yes. Apollo Industries is an authorized Whittet-Higgins retailer, and every Whittet-Higgins part we sell is genuine, made by Whittet-Higgins in Central Falls, Rhode Island, USA.
Do you ship the BMM-22 the same day?
