Overview
Whittet-Higgins BHS-18 Bearhug retaining nut
The Whittet-Higgins BEARHUG (stainless) is a one-piece, prevailing-torque self-locking bearing retention nut that replaces the traditional locknut-and-lockwasher assembly. A stainless steel nut body works with an integral heat-stabilized polymer locking ring to grip the shaft thread and hold preload against vibration, shock and torque, without cutting a keyway or damaging the shaft threads.
Its balanced construction suits higher-speed, high-precision and corrosive-environment assemblies while providing infinite adjustment and preloading. The BEARHUG (stainless) meets and exceeds ANSI/ABMA 8.2-1999, carries a 160 degrees F maximum operating temperature, and is manufactured in the USA and RoHS compliant.
Key features
- Prevailing torque self-locking design prevents the assembly from loosening due to vibration, shock and torque
- Corrosion-resistant stainless steel locknut with a heat-stabilized polymer locking ring
- Replaces the traditional locknut and lockwasher for easier, faster installation
- Does not damage shaft threads and eliminates the need to cut or repair a shaft keyway
- Infinite adjustment and preloading capability
- Balanced for higher-speed applications
- Meets and exceeds ANSI/ABMA 8.2-1999
- Maximum operating temperature of 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.

What thread does the BHS-18 fit?
The Whittet-Higgins BHS-18 fits a 3.527-12 right-hand shaft thread (89.59 mm, 12 threads per inch).
Does the BHS-18 need a lockwasher?
No. The Whittet-Higgins BHS-18 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 BHS-18?
Whittet-Higgins' BAS-18 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-18 rethreading die.

Whittet-Higgins rates the Bearhug BHS series (stainless) for up to 160 °F (71 °C).
What is the BHS-18 made of?
Locknut: stainless steel; Locking ring: heat-stabilized polymer.
Is there a drawing or CAD model of the BHS-18?
Yes. Whittet-Higgins publishes a part print (PDF) and a 3D CAD model (STEP) for the BHS-18. The drawing on this page is made from the same catalog dimensions.
How do I install the BHS-18?
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-18 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?
