What Is a Shaft Collar?

A shaft collar is a simple mechanical component designed to secure and position parts on a shaft. This cylindrical ring, commonly crafted from steel, aluminum, or stainless steel, fits around the shaft to hold components in place. Shaft collars are widely used across various applications, including conveyor systems, pumps, and machine tools.

The primary functions of shaft collars are to prevent parts from sliding off the shaft’s end, maintain their position along the shaft, and serve as stopping points for other components. They also assist in aligning parts and evenly distributing loads along the shaft, enhancing stability and performance.

Shaft collars are available in various types and sizes, such as set screw, clamp, and split collars. Set screw collars, the most commonly used type, are secured to the shaft using a set screw. Clamp collars use a two-piece design that tightens around the shaft with screws or bolts, while split collars, similar in design, can be installed or removed without disassembling other parts on the shaft.

Types of Shaft Collars

Shaft collars serve three primary functions: securing components in place, positioning or locating components along a shaft, and connecting the shaft to other parts. To accommodate various applications, manufacturers and distributors provide a diverse selection of shaft collars tailored to meet specific needs. Below are some examples of commonly available types.

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 bearing faces. They are easy to install and tighten.

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 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 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 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 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

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 & 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.

 Applications of Shaft Collars

Shaft collars are essential across various industries in Argentina and its surrounding regions, thanks to their versatility and secure functionality. In Buenos Aires and Córdoba, for instance, shaft collars play a vital role in conveyor systems by securing rollers and preventing components from slipping off shafts, which is crucial for the local logistics and industrial sectors. Similarly, in pump applications in cities like Mendoza and Rosario, shaft collars ensure impellers and other parts remain firmly in place, reducing the risk of movement or misalignment that could disrupt operations.

The machine tool industry in Santa Fe and San Juan relies on shaft collars to help with precise alignment along the shaft, serving as reliable stopping points for other parts. Meanwhile, in the growing robotics industry in La Plata and Mar del Plata, shaft collars are used to secure and position essential components, such as gears and pulleys, ensuring smooth, controlled movements within these systems.

Agricultural machinery across the fertile Pampas region and the automotive sector in Buenos Aires heavily utilize shaft collars to secure parts like blades, rollers, and engine components on transmission shafts. In the healthcare sector across Argentina, including medical facilities in Mendoza and Rosario, shaft collars are used in surgical instruments and diagnostic devices to ensure the precise positioning and stability of components. Their reliability makes shaft collars indispensable in industries throughout Argentina and its neighboring regions.
