Precision-machined, drop-forged, heat-treated Cr-Si-Mn-Mo SAE 4140 (42Cr, Mo4) steel eccentric shaft. The larger eccentricity of pitman shaft provides a motion that forces the material to the bottom of the jaw plate.
Spherical, self-aligning roller bearings, straight-bore pitman bearings and tapered-bore body bearings provide maximum strength to the pitman shaft and bearings for a long extended maintenance life.
The jaw crusher is one of the most indispensable and preferred machines because of its performance and durability. Depending on plant layout, jaw Crusher can be produced on wheels, skid-mounted or fixed to the concrete foundations.
