bushing car suspension

Specification: M34*∅46*103
Material: alloy steel
Continuous vibrations during vehicle operation can easily cause loosening of the pins or bolts that secure the leaf springs. In severe cases, this may lead to safety accidents. This threaded bushing, with its wire thread insert structure, can provide continuous radial elastic force to firmly lock the bolts, effectively preventing loosening, which directly improves the reliability and safety of the suspension system.
The direct hard contact between the leaf spring eye and the pin not only causes rapid wear but also generates huge noise due to friction and impact, seriously affecting driving comfort. This threaded bushing has inherent elasticity and self-lubricating properties, so that it can effectively absorb and cushion minor shocks and vibrations, significantly reducing operating noise and providing the smoother and quieter driving experience.
Without this threaded bushing, once the leaf spring eye is worn, repair becomes extremely difficult. It requires build-up welding followed by re-boring, and in some cases, repair is even impossible, forcing the replacement of the entire set of leaf springs. This results in high costs and long consumed time.
In summary, this threaded bushing is by no means a dispensable component. Instead, it is a precision-engineered functional and protective part. It plays a crucial role in improving the overall durability, safety, and cost-effectiveness of the vehicle’s suspension system.
