A “PU bush” typically refers to a bushing made of polyurethane (PU), a synthetic polymer known for its durability, resilience, and resistance to abrasion, chemicals, and weathering. PU bushes are used in various mechanical applications, particularly in automotive suspension systems and industrial machinery.
These bushings serve to provide a cushioned and durable interface between two mating parts, such as a suspension arm and chassis or a pivot point in machinery. They absorb shocks, dampen vibrations, and reduce noise, enhancing vehicle or machinery performance, comfort, and stability.
Compared to traditional rubber bushings, PU bushes often offer superior performance and longevity, making them popular upgrades in automotive tuning and aftermarket applications. They can withstand higher loads and temperatures while maintaining their properties over extended periods of use.
PU bushes are available in different shapes, sizes, and durometers (hardness levels) to suit specific application requirements. They are commonly used in suspension systems, steering components, and various linkage systems where durability, precision, and performance are crucial.
