Overview
Whittet-Higgins BMS-16 Bearhug retaining nu tstainless
The Whittet-Higgins BMS-16 is a stainless steel BEARHUG prevailing-torque self-locking bearing locknut from the metric BMS series. It threads directly onto a shaft and locks through a heat-stabilized polymer locking ring that generates prevailing torque, keeping the assembly secure against vibration, shock, and torque without damaging the shaft threads.
The integral locking ring eliminates the traditional locknut-and-lockwasher pairing as well as the need to cut or repair a shaft keyway, while still allowing infinite adjustment and preload. Balanced for higher-speed service and built from corrosion-resistant stainless steel, it meets and exceeds ISO 2982-2:2013(E), is rated to a maximum operating temperature of 160 deg F, 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
BMS-16 questions & answers
What size is the Whittet-Higgins BMS-16?
The Whittet-Higgins BMS-16 is a Bearhug self-locking locknut. Thread: M80 × 2 (pitch 2 mm). Outside diameter: 105.0 mm (4.134 in). Face diameter: 95.0 mm (3.740 in). Width: 17.0 mm (0.669 in). These are Whittet-Higgins' maximum sizes from its spec sheet.
What thread does the BMS-16 fit?
The Whittet-Higgins BMS-16 fits a M80 × 2 right-hand shaft thread (pitch 2 mm).
Does the BMS-16 need a lockwasher?
No. The Whittet-Higgins BMS-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 BMS-16?
Whittet-Higgins' BASM-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 RTDM-16 rethreading die.
What temperature can the BMS-16 take?
Whittet-Higgins rates the Bearhug BMS series (stainless) for up to 160 °F (71 °C).
What is the BMS-16 made of?
Locknut: stainless steel; Locking ring: heat-stabilized polymer.
Is there a drawing or CAD model of the BMS-16?
Yes. Whittet-Higgins publishes a part print (PDF) and a 3D CAD model (STEP) for the BMS-16. The drawing on this page is made from the same catalog dimensions.
How do I install the BMS-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 BASM-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.
Do you ship the BMS-16 the same day?
