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.

How to Select the Right Clamp Collar or Coupling for Your Application

Whether a clamp collar and coupling style is the right choice for your specific application is based on several factors, including:

  • Operating environment
  • Diameter of the shaft
  • Load capacity
  • Necessary features and design elements

When in doubt, our expert team can guide you to the best choice for your application.

Frequently Asked Questions (FAQs)

What benefits do low profile shaft collars & couplings offer?

Low profile shaft collars and couplings achieve maximum space economy while reliably securing and aligning shaft components. Their compact design makes them an optimal choice for areas with limited space.

What about high strength shaft collars & couplings makes them different?

These durable, high-strength components can operate dependably when faced with high torque and heavy loads. Their strength is sufficient for a wide variety of r industrial projects.

When is it appropriate to use heavy duty shaft collars & couplings?

These shaft collars and couplings deliver rugged strength and maximum holding power. They perform reliably when presented with excessive vibrations, high-speed rotations, and other challenging environments.

Can you customize shaft collars & couplings to fit my requirements?

Yes. We’re capable of providing customized shaft collars and couplings that suit your unique requirements for size, style, material, coating, and more.

Are shaft collars & couplings easy to install?

Yes. Correct installation is vital to a shaft collar or coupling’s dependable performance. However, with installation techniques such as clamp screws, set screws, and hinged designs, our shaft collars and couplings are typically quite simple to install.

How do I properly maintain shaft collars & couplings?

With minimal maintenance needs, it’s typically enough to inspect shaft collars and couplings periodically for alignment, lubrication, and wear to prevent part failure and promote longevity.
