PU Bush is also known as a polyurethane bushing, is a type of suspension bushing used in automotive and industrial applications. It is made from a durable and flexible material called polyurethane, which provides superior strength, heat resistance, and vibration damping properties compared to traditional rubber bushings. PU Bush is commonly utilized in suspension systems to improve handling and reduce noise and vibration. They are also used in machinery to reduce wear and tear and improve stability. One of the major advantages of PU bushings is their longevity.
