Metric Series Set Screw Shaft Collar

A metric series set screw shaft collar is a mechanical component used in machinery to secure rotating shafts. It is specifically designed to fit shafts with metric dimensions.

Metric Series Set Screw Shaft Collar

A shaft collar is a cylindrical device that fits around a shaft and is usually made of metal or plastic. It typically has a set screw that is tightened onto the shaft to hold the collar in place. The set screw is tightened using an Allen wrench or similar tool, and it creates a frictional force between the collar and the shaft, preventing slippage or movement.

The metric series refers to the collar's dimensions, which are based on the metric system. These collars are designed to fit shafts with metric diameters, such as those measured in millimeters.

Shaft collars have various applications, including providing support, locating components, or acting as mechanical stops. They are commonly used in machinery and equipment to secure rotating shafts, such as in conveyor systems, power transmission systems, and various types of machinery.

Set Screw Shaft Collar Characteristics

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.
