Crusher bearings are a type of bearing specifically designed for use in crusher equipment and are capable of withstanding the enormous impact loads, radial loads, and axial loads generated during crushing operations. When the crusher is operating, materials are crushed through the extrusion, impact, and shearing of crushing components such as the jaw plate, cone, and rotor. This process generates violent vibrations, momentary shocks, and continuous heavy loads. Especially when processing materials such as hard ores and large rocks, bearings must withstand loads far exceeding those of ordinary machinery, and may also be exposed to harsh environments characterized by dense dust and high temperatures. Therefore, crusher bearings are specially designed in terms of structural strength, material properties, and lubrication and sealing. Their core characteristics are superior load-bearing capacity, impact toughness, and wear resistance, enabling them to maintain stable operation under extreme working conditions.
