Product Overview

Round bore shaft collars are used in mechanical assemblies as locators, stops, bearing faces, spacers, and mounting components. They are clamping devices for power transmission, motion control, and mounting applications.

They can be used on shafts, tubing, pipe, and split hubs in both rotary and non-rotary applications. Learn more about our round bore shaft collars.

Rigid shaft couplings connect or “couple” two shafts that are in alignment with one another. By clamping the two shafts together, these mechanical components allow rotary motion to be transferred from one rotating shaft (the driving shaft) to the other (the driven shaft).

This simple and robust design enables the coupling to transmit more power than comparable flexible shaft couplings. Given these considerations, industry professionals typically use rigid shaft couplings only in applications where the shafts are coaxial and/or pre-positioned in precise alignment with each other.

Stafford Manufacturing manufactures and distributes a vast selection of rigid shaft couplings for consumer and industrial products. Our couplings can be found in motion control, automation, power transmission, and other OEM and MRO applications.

Threaded shaft collars are ideal for a specific threaded shaft or screw, such as Unified National Fine (UNF), Unified National Coarse (UNC), and Acme threads. They clamp in place for secure positioning and will not damage the threads. Check out our product catalog of threaded shaft collars. 

Threaded shaft collars are commonly used as a stop to position components or to prevent specific parts from running along a shaft or line. Its improved grip makes it ideal for applications requiring extremely precise location and preload settings.

With one-piece, two-piece, and hinged clamp styles, threaded bore shaft collars are easy to assemble and adjust. Specialty collars include Accu-Clamp™threaded bore and threaded hub collars.

Stafford’s Accu-Clamp™ products have a non-clamping section as well as a clamping section. The non-clamping section is made up of a rigid bore that can maintain its shape without flexing or distorting during use. The flexible, cantilevered clamping section provides non-marring, proportionally distributed holding power.

Our Accu-Clamp™ products have a special design with a precision machined face that lines up with the shaft within 0.001 TIR. Its slotless design allows for a continuous outside diameter surface that can be machined, profiled, or knurled to meet the needs of any application. Because the face is slotless, it provides a complete 360° surface that can be ground, hardened, machined, or flanged to meet various mounting and tolerance requirements, as well as be outfitted with other features. 

Accu-Clamp™ products are ideal for use in applications that require easily machined and hardened steel products.

Stafford Manufacturing manufactures and distributes a diverse range of products for use in power transmission, motion control, automation, and other OEM and MRO applications. We offer a variety of shaft collars, including flanged shaft collars—one of our main product categories.

In comparison to other flanged shaft collars on the market, ours feature:

• More secure attachment options without the need for welding
• Reduced risk of shaft damage
• More customizability for specific user requirements

The square and hexagonal bore shapes provide a standard solution to specialized problems, such as those found in food processing, agricultural, and conveyor systems.

Our Stafford-exclusive square and hexagonal bore shaft collars and couplings are intended to fit square and hexagonal shafts. Clients can also choose from a wide range of standard bore sizes based on their applications. These one-piece or two-piece split clamp-style collars can be installed anywhere on a shaft, and the smooth bore protects the shaft from marring.

Metric products and components are classified separately according to convention. They have the same shape and function as their counterparts measured in inches but are fully metric in every way, including hardware.
