QINDING track support rollers are key components for supporting the weight of construction machinery. They are forged from high-quality materials such as 40MnB Steel, undergo mechanical processing and heat treatment, and the surface of the rollers, after quenching, reaches a hardness of HRC 52-60 , featuring strong wear resistance.
Equipped with advanced sealing technology, they effectively isolate mud, water and dust, prolonging service life and adapting to harsh working conditions. Classified by structure into single-sided and double-sided support rollers, they can meet the needs of different machinery. With scientific design and low rolling resistance, they contribute to the efficient operation of machinery, making them a reliable choice for your construction machinery.
