Inch Series Set Screw Shaft Collar

Inch Series Set Screw Shaft Collar

Set screw shaft collars are commonly used in various industries and applications, such as machinery, robotics, conveyor systems, and power transmission. They provide a simple and effective means of securing components to shafts, offering stability and reliability.

Shaft Collar: The main component of a set screw shaft collar is the collar itself. It is a cylindrical ring that fits around the shaft. The collar typically has a threaded hole or holes in it to accommodate set screws.

Set Screws: These are small screws that are inserted into the threaded holes in the collar. When tightened, the set screws dig into the shaft, creating a secure grip and preventing the collar from sliding or rotating along the shaft.

Bore: The central hole in the collar is called the bore. It has a specific inner diameter that matches the shaft size. The collar fits snugly around the shaft, allowing it to be positioned at a desired location.

Clamping Force: When the set screws are tightened against the shaft, they generate a clamping force. This force ensures that the collar remains fixed in place, preventing any movement or slippage.

Adjustability: Set screw shaft collars offer some level of adjustability. The set screws can be loosened or tightened to adjust the collar's position along the shaft, making it suitable for various applications.

Set Screw Shaft Collar Features

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 collar 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.
