Precision

Accuracy is the relationship between the face of the collar and its perpendicularity to the hole. A groove is machined into the face of the collar to indicate vertical accuracy and which side of the collar is load bearing.

Clamping Force

Clamping force between different shaft collar types varies. Solid, set screw shaft collars provide the lowest amount of holding power through the single set screw that engages the mating shaft.

Bore Size

If the bore size is too big, the collar will not provide adequate clamping force on intended shaft and may prematurely release. Conversely, if the bore is too small, it will not fit on the shaft.

How does a Shaft Collar / Set Collar work?

Using an adjustable screw the set collar can be tightened securely and released freely.The screws on Clamp-style shaft collars act to compress the collar and lock it into place using friction. They are easy to use and do not damage the shaft. The compression of the screws on the collar imposes a uniform distribution of force on the shaft.

Shaft collars/Set Collars as they are also known, allow the positioning of tools and attachments to a shaft.

Where is a Shaft Collar / Set Collar used?

Shaft Collars/Set Collars are usually found in power transmission applications, such as motors and gearboxes.

What are the different types of shaft collars?

There are a wide variety of shaft collars to choose from. The most popular styles are set screw, single split, double split, and threaded. Each style has their own unique benefits in a given application.

What are some design considerations for shaft collars?

About Shaft Collar

Shaft collars are one of the simplest components in machine design but are also one of the most indispensable. Shaft collars can be found in virtually any type of machinery and are frequently accessories to other components. Capable of fulfilling many roles, shaft collars often hold bearings and sprockets on shafts, situate components in motor and gearbox assemblies, and serve as mechanical stops.

Shaft collars are used in many industrial equipment and systems, including: as positioning and alignment bearings, gears, pulleys and other moving parts. In laboratory equipment such as clamps and frames, shaft collars serve as precise and easily adjustable stops and spacers. In trucks and off-road vehicles, shaft collars act as mechanical stops for cylinders, actuators, and other components. During power transmission operations, the shaft collar assists in the positioning of the motor and transmission components.
