The jaw crusher is composed of two jaws, one is fixed firmly with the crusher frame, and the another is being mount by a pitman mechanism. The moving jaw moves backwards and forwards quickly between a small throw to crush the ore. As the moment of jaw plate is small, the crushing can be done in one stroke.

The pin is 2-1/2 IN solid round stock. The knuckle is a 2-1/2 section of well casing. The jaw will be welded to the knuckle and will pivot around the pin. So the bottom of the jaw seen in this pix will travel an arc as the other end of the jaw rides on the eccentric shaft. A small arc but an arc nonetheless.
