Set Screw Shaft Collars (Solid Shaft Collars)

A set screw shaft collar (solid shaft collar) is a clamp-like device that is used to position and locate components on a shaft. They are also used to limit shaft movement. Set screw shaft collars are usually made of aluminum, stainless steel, or zinc-plated steel. The zinc coating helps to create a corrosion-resistant finish. They are also easy to install and tighten. They are also available in different sizes. To find the right set screw shaft collar for your needs, contact us.

Set Screw Shaft Collars (Solid Shaft Collars)

A set screw shaft collar is a mechanical component that is used to secure and position a rotating shaft in a specific location on a machine or other piece of equipment. The set screw shaft collars are typically made of metal and consist of a cylindrical shape with a hole in the center that is slightly smaller than the diameter of the shaft. The set screw shaft collars are designed to be clamped around the shaft using set screws, which are small screws that are threaded into the collar and tightened against the shaft to hold it in place.

Set screw shaft collars are used in a variety of applications, such as motors, pumps, and other industrial equipment. The main function of a set screw shaft collar is to prevent the shaft from moving in a lateral direction, which can cause damage to the equipment or interfere with the operation of the machine. The set screw shaft collars also provide a surface for attaching other components, such as pulleys or gears, to the shaft.

Set screw shaft collars come in different sizes and materials. They are usually made of aluminum, stainless steel, or zinc-plated steel. Some types are also available in black oxide steel or plastic. These set screw shaft collars are usually available in stock or as a custom size. Bore sizes range from 3/16″ to 4″ and 4mm to 50mm.

▍Features of Set Screw Shaft Collars

Set screw shaft collars are used in a variety of applications. These parts act as precise stops and spacers in lab equipment, including optical measuring instruments and hospital bed positioning systems. They are also commonly used on plastic, glass, and thin-wall tubing. This type of set screw shaft collars can withstand the demands of many medical applications, such as operating on patients and MRIs.

The axial holding power of a set screw shaft collar depends on its size, the applied torque, and the hardness and finish of the shaft. Different materials have different performance characteristics, and choosing the right material is vital to ensuring proper shaft alignment. For example, aluminum set screw shaft collar is lightweight, but offers high holding power. Stainless steel shaft collars are more durable, and can withstand harsh environments. When choosing the material, it’s also important to consider the environment the set screw shaft collar will be operating in. A shaft collar that is not suited to the operating environment may be prone to corrosion, which will compromise performance and lead to premature failure.

A set screw shaft collar’s holding power is dependent on how effectively it can impinge on the shaft. The screw and shaft material must be compatible to ensure optimal holding power. This means that set screw shaft collars should be compatible with all types of shafts. However, if you are unsure of which material works best with which shaft material, it may be best to consult a technician. You can use a torque wrench to control the final torque.

▍Applications of Set Screw Shaft Collars

Set screw shaft collars are simple mechanical devices that are used to secure components onto a shaft, prevent axial movement of components along the shaft, or act as a stop on the shaft. Here are some application scenarios where set screw shaft collars are commonly used:

(1) Positioning: Set screw shaft collars are often used to position components along a shaft. For example, they can be used to keep bearings or gears in place on a shaft, ensuring that they are properly aligned and spaced.

(2) Stop: Set screw shaft collars can be used as physical stops on a shaft. For example, they can be used to limit the travel of a linear actuator or to prevent a pulley from sliding off the end of a shaft.

(3) Clamping: Set screw shaft collars can also be used for clamping applications, such as securing a tool or fixture onto a shaft. They provide a simple and effective way to hold components in place without requiring complex mounting hardware.

(4) Adjustment: Set screw shaft collars can be used to adjust the position of components along a shaft. For example, they can be used to adjust the tension on a belt drive system or to fine-tune the position of a sensor or encoder.

(5) Protection: Set screw shaft collars can also be used to protect the ends of shafts from damage. For example, they can be used to prevent shafts from being bent or dented during handling or transportation.
