The jaw plates are fixed on the jaw bed with bolts and wedge screws. The jaw bed of the fixed jaw plate is the front wall of the frame. The jaw bed of a mobile crusher jaw plate must have sufficient strength and stiffness to stand the broken reactive force, and thus most mobile jaw plates are made of cast steel or cast iron pieces.

For example, a 32 x 54 sized jaw crusher will measure 32 inches from the movable to stationary jaw (when measured at the top i.e. the opening), and each jaw will have a 54-inch width. If a jaw crusher is rated by jaw plate size, a suitable rating maybe 600 x 400, which indicates a 600 mm by 400 mm jaw plate dimension.
