Eccentric Shaft
High strength alloy steel, forged plank processing, with high strength, high hardenability, good toughness, small deformation during quenching, high creep strength and endurance strength at high
temperatures.
Bearings
Imported high-quality spherical roller bearings improve jaw crusher reliability and automatic centering performance; optimized design to bear radial heavy loads and certain bidirectional axial loads; self guiding rollers can keep friction and heat generated by friction at a relatively low level.
PITMAN
High-quality cast steel parts; the structural strength, stiffness and fatigue life of PITMAN are calculated through finite element analysis (FEA). The areas with the largest force are strengthened, and the areas with small stress are lightened.
