What Is a Shaft Collar?

A shaft collar is a simple machine component, but its function is important in many power transmission applications. Most commonly, shaft collars are used in motors and gearboxes. They can act as locating components, bearing faces, and mechanical stops. Their compact design makes them easy to install. In addition, they provide a clean, simple look for your gearbox or motor.

Sizes

There are a variety of sizes of shaft collars. Each type has different parameters and requirements. These specifications can be found on the manufacturer’s website. These dimensions are important for the selection process. In order to determine which size is best for your needs, first identify the system parameters and limitations that you’ll be using.
Shaft collars are available in a variety of sizes and materials. These pieces can range in thickness from just a few millimeters to several inches. A solid steel shaft collar is usually available from 1/8″ to six inches. The material used for shaft collars is either 304 stainless steel or lead-free steel.
The oldest style of shaft collar is the set collar, which uses a hardened set screw to penetrate the shaft surface. It is ideal for holding bearings, spacers, and sprocket hubs. These collars are typically installed using hex keys, which are six-sided L-shaped tools, also known as Allen Wrenches. These collars are useful for many different machine applications, and are often used in conjunction with springs and dampers to hold components in place. They are also useful as mechanical stops, stroke limiters, and bearing holders.
Shaft collars come in one-piece and two-piece designs. A one-piece collar provides uniform holding force on the shaft, whereas a two-piece shaft collar is stronger and can be assembled anywhere on the shaft. Shaft collars are generally available in English and metric units, and the manufacturer can alter the dimensions of any standard collar to meet your needs. For more unique situations, you can also choose a fully customized shaft collar that is specific to your application.

Functions

A shaft collar is a metal or plastic device used to locate and position components on a shaft. It also limits the movement of the shaft. These devices can be found on a wide variety of applications, including motor assembly components. There are many types of shaft collars.

Clamp-type collars are reliable under constant loads, but may require additional support under shock loads. A shock load is a force generated by a relatively small mass that is rapidly increased by impact. Clamp-style collars are designed to counteract this force, and an undercut on the shaft may help them stay firmly in place. Clamp-style collars are also available in two-piece designs, which offer a high holding force and ease of assembly.
A shaft collar is an important machine component. It holds and positions sprockets on a shaft. It also acts as a mechanical stop, and helps prevent a shaft from slipping. They can also be used to limit the movement of cylinders and actuators. These simple components are found in virtually every type of machinery.
The torque-generating force in a set-screw shaft collar is absorbed by friction between the threads and the clamp body. The friction between these parts helps compensate for the lost torsioning effort, which can lead to the collar failing to hold. Alternatively, a torque wrench can help control the final torque of the shaft collar.

Types

There are many different types of shaft collars available for different applications. It is important to understand the characteristics of each to find the right one for your application. The most common shaft collars are made from steel or aluminum, but some are also made of plastic. These are relatively inexpensive and lightweight, but their holding power is limited. Titanium shaft collars are much lighter than aluminum and are resistant to extreme temperatures, but they are only used in a few specific applications.
Another type is a clamp collar, which is mounted using a compression method. Compared to the set screw type, clamp collars are much stronger and have a higher holding power. Clamp collars come in either a one-piece or two-piece design. One-piece collars are used in applications where the shaft is split and requires a positive stop.
The strength of a shaft collar depends on the type of screw used to attach it to the shaft. The screw’s strength and diameter will affect the holding power of the shaft collar. In most cases, a manufacturer will offer the proper screw with the collar. In some cases, however, a non-standard screw may be more appropriate.
The set screw collar is one of the oldest types. Its disadvantage is that it can be difficult to move and may damage the shaft. Also, it is not as secure as a clamp-based collar. In addition, two-piece hinged shaft collars are the most convenient. One-piece collars are difficult to move, while two-piece collars can be moved easily along the shaft without separating components.

Dimensions

Shaft collars are a complex component and their dimensions are crucial to the performance of the application. Designing a shaft collar requires consideration of a variety of factors, such as the type of material, bore size and geometry of the shaft. The manufacturer of a shaft collar will usually publish performance data on its website, or users can contact them for assistance.
The material used in shaft collars has a significant impact on the collar’s strength and its holding capacity. Shaft collars should be made from a high-quality, corrosion-resistant material. The strength of the screw also plays an important role in the collar’s holding capacity. Generally, a collar’s manufacturer will provide the appropriate type of screw for the application. However, in some cases, a non-standard screw may be necessary.
Shaft collars are available in a variety of styles. One-piece collars are often used in applications where there is minimal or no disassembly or adjustment required. Alternatively, two-piece collars may be used when frequent disassembly is needed. Regardless of the style, the size of shaft collars should be consistent with the requirements of the assembly.
Shaft collars are made from steel or aluminum. They offer good holding power and are lightweight. Steel shaft collars are durable and have good corrosion resistance. However, the grade of steel can affect their performance. Stainless steel collars are easier to machine and have improved corrosion resistance. However, they may reduce the holding power.

Stainless steel

A stainless steel shaft collar is a simple mechanical component used to secure a shaft. It is used for many different applications, most commonly in motors and gearboxes. They also function as locating components, mechanical stops, and bearing faces. These collars are available in different sizes and can be used for a variety of different purposes.
Shaft collars come in various materials, including stainless steel, aluminum, and polyamide. They are available with a variety of different finishes, including electroless nickel plating.
