Overview
Whittet-Higgins BHL-03 Bearhug left handed retaining nut
The Whittet-Higgins BEARHUG is a left-handed, prevailing-torque self-locking bearing locknut that secures and preloads bearings, sleeves, and other components on a threaded shaft. Its left-hand thread keeps clockwise-rotating assemblies from backing off, while an integral heat-stabilized polymer locking ring develops prevailing torque to resist loosening from vibration, shock, and torque without a separate lockwasher or shaft keyway.
Built with a carbon steel locknut body, it offers infinite adjustment and preloading capability and installs faster than a traditional locknut-and-lockwasher combination, while being balanced for higher-speed, high-precision assemblies. The BEARHUG meets and exceeds ANSI/ABMA 8.2-1999, is rated to a 160 deg F maximum operating temperature, and is 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
BHL-03 questions & answers
What size is the Whittet-Higgins BHL-03?
The Whittet-Higgins BHL-03 is a Bearhug self-locking locknut. Thread: 0.664-32 (16.87 mm, 32 threads per inch). Outside diameter: 1.125 in (28.57 mm). Face diameter: 0.938 in (23.83 mm). Width: 0.406 in (10.31 mm). These are Whittet-Higgins' maximum sizes from its spec sheet.
What thread does the BHL-03 fit?
The Whittet-Higgins BHL-03 fits a 0.664-32 left-hand shaft thread (16.87 mm, 32 threads per inch). A left-hand thread keeps the nut from working loose where the shaft's rotation would loosen a right-hand nut.
Does the BHL-03 need a lockwasher?
No. The Whittet-Higgins BHL-03 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 BHL-03?
Whittet-Higgins' BAS-03 assembly socket: it holds all four spanner slots and takes a square-drive ratchet or torque wrench.
What temperature can the BHL-03 take?
Whittet-Higgins rates the Bearhug BHL series (left-handed) for up to 160 °F (71 °C).
What is the BHL-03 made of?
Locknut: carbon steel; Locking ring: heat-stabilized polymer.
Is there a drawing or CAD model of the BHL-03?
Yes. Whittet-Higgins publishes a part print (PDF) and a 3D CAD model (STEP) for the BHL-03. The drawing on this page is made from the same catalog dimensions.
How do I install the BHL-03?
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-03 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 BHL-03 the same day?
In-stock orders placed by 3 PM EST ship the same day. All orders over $100 ship free by ground with code FREESHIP.
Can I get quantity pricing or buy tax-exempt?
