The bushings https://styknews.info/novyny/novyny/2025/01/03/chugunnaya-vtulka are made of high-quality cast iron with a phosphate coating, which increases corrosion resistance, maintains its appearance for a long time and facilitates dismantling during maintenance. The bushings are manufactured on machines, due to which it is possible to achieve high precision of surfaces and angles for maximum contact with mating parts. This increases the transmitted torque and resistance to impact loads.
