The shaft collar is a simple, yet important, machine component
found in many power transmission applications. The collars are used
as mechanical stops, locating components and bearing faces. The
simple design of a shaft collar lends itself to easy installation.
The two main types of shaft collars are the set screw collar and
the clamping collar. Shaft collars are available in many materials,
such as steel, stainless steel, aluminum and nylon materials.
The set screw shaft collar was the original collar utilized in
industrial applications. Set screw shaft collars utilize a solid
ring and screws that screw directly into the shaft. Set screw shaft
collars are best used when the material of the shaft is softer than
the set screw. Unfortunately, the set screw causes damage to the
shaft which makes the collar harder to adjust or remove.
Clamping shaft collars come in one and two-piece designs that
utilize screws to compress the collar and lock it into place around
the shaft. The ease of use is maintained with the clamp shaft
collar design, eliminating shaft damage. Since the screws compress
the collar, a uniform distribution of force is imposed on the
shaft, leading to a holding power that is nearly twice that of set
screw shaft collars.
