Shaft collar

The shaft collar is a simple yet important machine component found in many power transmission applications, most notably motors and gearboxes. Shaft collars are used as mechanical stops, as a way of locating other components along a shaft, and as bearing faces. Their simple design lends itself to easy installation, which is a large part of their appeal for engineers who need to position a part on a shaft without a more elaborate fixing. This atlas treats the shaft collar as an industrial component, a low-cost hardware item that supports the power transmission equipment around it.
