Shaft Collars

Shaft collars are used to position and locate components on a shaft. They also help to limit the movement of the shaft. There are many different types of shaft collars available. Each of these collars has different characteristics. As a professional manufacturer and distributor of shaft collars, we also provide custom shaft collars with special requirements.

Shaft Collars

What Is a Shaft Collar?

A shaft collar is a mechanical device that is used to secure and position components on a shaft. It is a simple device that consists of a cylindrical ring that is usually made of steel, aluminum , or stainless steel, and is designed to fit around the shaft. Shaft collars can be used in a variety of applications, such as on conveyor systems, pumps, and machine tools.

Shaft collars are typically used to prevent components from sliding off the end of a shaft, to keep them in a specific position along the shaft, or to provide a stopping point for other components. They can also be used to help align components on a shaft or to help distribute loads evenly across the shaft.

Shaft collars come in different types and sizes, including set screw shaft collars, clamp shaft collars, and split collars. Set screw shaft collars are the most common type and are secured in place on the shaft using a set screw that is tightened against the shaft. Clamp shaft collars use a two-piece design that clamps around the shaft and is tightened using screws or bolts. Split shaft collars are similar to clamp shaft collars but have a split design that allows them to be installed or removed from the shaft without having to disassemble other components.

Types of Shaft Collars

Three primary functions are provided by shaft collars:

1) Keeping components in place

2) Locating or positioning components on a shaft

3) Attaching the shaft to another component.

Manufacturers and distributors offer a wide range of shaft collars to meet the needs of different applications. Here are some examples of types of shaft collars that are commonly available.

Set Screw Shaft Collars

Set Screw Shaft Collars

A set screw shaft collar will withstand a high amount of force. Set screw shaft collars are economical. They are durable, lightweight, and do not require specialized tools. They are set in position with a hardened set screw that penetrates the shaft. Set screw shaft collars are used on shafts in a variety of applications, including as mechanical stops, locating components, and faces. They are easy to install and tighten.

 

 

Single Split Shaft Collars

Single Split Shaft Collars

Single split shaft collars are a great choice for hard and soft standard round shafts. They offer a superior grip over solid collars and tremendous axial power. They also minimize shaft distortion. These collars can be adjusted to fit virtually any shaft diameter. They are easy to install and remove, and are easily adjustable.

 

 

Double Split Shaft Collars

Double Split Shaft Collars

Double-split shaft collars can be described as a kind of shaft collar comprised of two distinct components. They are easily disassembled which allows them to be utilized in situations where the top of the shaft isn't accessible. Two-piece shaft collars offer more hold force and resistance to shock load when compared to single-piece counterparts because they are able to make use of all of the seating torque they have to generate compression forces around the shaft. They are an excellent choice for a variety of applications.

 

 

Heavy Duty Shaft Collars

Heavy duty shaft collars feature larger outer diameters, wider widths, and larger screws to hold shafts in place. They come in three to six-inch bore sizes and are available in two-piece and one-piece clamp styles. Heavy duty shaft collars can accommodate high axial loads and can also be used in applications that require frequent axial adjustment. A two-piece clamp collar is better for applications that require frequent disassembly and adjustment. These collars are available in both metric and Inch measurements. They can also be disassembled and reassembled without tools.

 

 

Double Wide Shaft Collars

Double Wide Shaft Collars

Double wide shaft collars are a type of shaft collar that is wider than standard shaft collars. This increased width provides them with greater holding power, making them ideal for applications with high axial loads. There are two main types of double wide shaft collars: one-piece and two-piece. One-piece double wide shaft collars are a single, solid piece of material. Two-piece double wide shaft collars are made up of two halves that are bolted together. Double wide shaft collars are available in a variety of materials, including steel, stainless steel, and aluminum. They are also available in a variety of sizes, so you can find the perfect one for your application.

 

 

Threaded Shaft Collars

Threaded Shaft Collars

Threaded shaft collars are mechanical components used to secure and position components on a shaft. They are typically made of metal or plastic and consist of a cylindrical body with a threaded bore that allows them to be tightened down onto a shaft. They may also have set screws or clamping mechanisms to provide additional holding force. Threaded shaft collars are commonly used in machinery and equipment to hold bearings, pulleys, gears, and other components in place. They can also be used to create stops or limit switches on a shaft or to provide a mounting point for sensors or other devices.

 

 

Thin Line Shaft Collars

Thin line shaft collars are a type of mechanical component used to secure and position objects on a shaft. They are similar to traditional shaft collars but with a thinner profile. Thin line shaft collars are typically made from materials such as aluminum, stainless steel, or steel. They have a simple design consisting of a circular ring with a small screw or set screw used to tighten the shaft collar onto the shaft. The thin profile of these shaft collars makes them ideal for use in applications where space is limited or where a bulky shaft collar would interfere with other components.

 

 

Keyed Shaft Collars

Keyed Shaft Collars

A keyed shaft collar is a mechanical component used to fasten a rotating shaft to a stationary component, such as a bearing or a shaft-hub connection. It is designed to lock onto a shaft with a keyway to prevent slippage or rotation of the shaft collars and any attached components. The keyway is a slot or groove machined into the shaft, which allows the shaft collars to be positioned in a fixed location along the shaft. A matching key is then inserted into the slot or groove, providing a positive mechanical connection between the shaft and the shaft collars.

 

 

Hex Bore Shaft Collars

Hex & D Bore Shaft Collars

Hex & D bore shaft collars are types of mechanical components used to secure a shaft or rod in place. They are typically made of steel, aluminum, or stainless steel and consist of a cylindrical ring with a set screw or other fastening mechanism to grip the shaft. Both hex and D bore shaft collars are commonly used in a variety of industrial and mechanical applications, including in machinery, conveyor systems, and robotics. They are often used in conjunction with other components, such as bearings or pulleys, to provide secure and reliable shaft support.

What Is a Shaft Collar Used For?

Shaft collars can be used for holding flags on flag poles, positioning devices on medical equipment, and for more common industrial applications that hold other shaft assemblies such as bearings, sprockets, and pulleys in place.

What is the Bore Size on a Shaft Collar?

The bore size of shaft collars refers to the diameter of the shaft collar's inner diameter. The collar may not be able to clamp the shaft properly if the bore is too large.
