Overview
Whittet-Higgins BHM-16 Bearhug retaining nut hardened alloy
The Whittet-Higgins BEARHUG (BHM series) is a high-strength, prevailing-torque self-locking bearing locknut that threads onto a shaft or sleeve to retain and preload bearings without a separate lockwasher or a cut shaft keyway. A hardened alloy locknut body carries high axial loads, while an integral heat-stabilized polymer locking ring engages the threads to hold the assembly secure against vibration, shock, and torque.
It offers infinite adjustment and preloading capability without damaging the shaft threads, and is balanced for higher-speed, high-precision assemblies. The BEARHUG meets and exceeds ANSI/ABMA 8.2-1999 and is manufactured in the USA.
Key features
- Hardened alloy locknut with an integral heat-stabilized polymer locking ring

- Replaces the traditional locknut-and-lockwasher pair for easier, faster installation
- Eliminates the need to cut or repair a shaft keyway
- Infinite adjustment and preloading without damaging shaft threads
- Balanced design for higher-speed applications
- Meets and exceeds ANSI/ABMA 8.2-1999
- Maximum operating temperature 160 degrees F
- Manufactured in the USA and 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.

FAQ

What size is the Whittet-Higgins BHM-16?
The Whittet-Higgins BHM-16 is a Bearhug self-locking locknut. Thread: 3.137-12 (79.68 mm, 12 threads per inch). Outside diameter: 4.156 in (105.56 mm). Face diameter: 3.844 in (97.64 mm). Width: 0.656 in (16.66 mm). These are Whittet-Higgins' maximum sizes from its spec sheet.
What thread does the BHM-16 fit?
The Whittet-Higgins BHM-16 fits a 3.137-12 right-hand shaft thread (79.68 mm, 12 threads per inch).
Does the BHM-16 need a lockwasher?
No. The Whittet-Higgins BHM-16 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 BHM-16?
Whittet-Higgins' BAS-16 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 RTD-16 rethreading die.
What temperature can the BHM-16 take?
Whittet-Higgins rates the Bearhug BHM series (high strength) for up to 160 °F (71 °C).
What is the BHM-16 made of?
Locknut: hardened alloy; Locking ring: heat-stabilized polymer.
Is there a drawing or CAD model of the BHM-16?
Yes. Whittet-Higgins publishes a part print (PDF) and a 3D CAD model (STEP) for the BHM-16. The drawing on this page is made from the same catalog dimensions.
How do I install the BHM-16?
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 BAS-16 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.
