Clamp Collar & Clamp Coupling Styles

Clamp collars and rigid couplings effectively secure and position components along a machine’s shaft. Different styles are available to handle applications’ varied requirements for profile, material, load capacity, and holding power, as well as the collar or coupling’s operating environment.

Choosing the ideal style is essential for reliable equipment performance. At Stafford Manufacturing Corp., our clamp collars and couplings come in a range of inch and metric sizes, material options, and configurations. We can also tailor a component to suit your specific needs.

High Strength Style

Clamp Collars & Couplings: Holding Power Overview

We offer an array of clamp collar and coupling styles to provide options for diverse applications. When comparing Stafford shaft collars and couplings to other products, the generic terms “recessed screw” and “exposed screw” refer to high strength or low profile styles, respectively, as each company uses its own terminology. You can choose from:

High Strength Style

Recessed screw heads. In this reliable, all-purpose option, recessed screws offer a cleaner, smoother profile. The design enables our flagship clamp collars and couplings to meet tighter clearance requirements between the outer diameter (OD) and other parts.

High Strength Style

Low Profile Style

Protruding screw heads. A low profile shaft collar or coupling utilizes protruding screw heads that extend only slightly past a collar’s outer surface. Possessing a smaller OD, protruding head screws are still a good choice for applications in which clearance or space is a concern.

Low Profile Style

Heavy Duty Style

Large screws for enhanced power. Compared to our standard collar options, heavy duty shaft collars have a larger OD and use larger screws, resulting in double the axial loading power. Heavy duty couplings deliver triple the torsional holding power of high strength couplings, also with a larger OD and more clamping screws.
