Polyurethane Front Strut Top Mount Bushings

Shanghai Pepsen manufactures standard and custom polyurethane front strut top mount bushings as per customer requirements including drawings or samples. Hardness is normally Shore 85-90A, but can vary as well as color. 

What is polyurethane front strut top mount bushings?

Polyurethane has been widely known for its excellent abrasion and impact resistance, it is widely used in motor industry and the suspension bushings and mounts are one of typical applications. The polyether based polyurethane is more resilient while polyester one is more resistant to impact, abrasion, oil and high temperature.

The original factory car bushings and mounts are manufactured from rubber which deteriorate with age. They becomes softer and more fragile. Over a period of time, stress and strain begin to weaken and crack the factory fit rubber mounts. This results in poor handling and vague steering. Tracking and camber can also be affected.

Polyurethane top mounts are the ideal replacement for rubber front strut mount bushings.

What are advantages of polyurethane front strut top mount bushings?

Wear resistance

Impact and shock absorption.

Oil and chemical resistant.

Reduce noise significantly.

Exceptionally long service life.

How does polyurethane front strut top mount bushing work?

Rubber top mounts which deteriorate with age causing more and more movement of suspension parts and offering less and less control over the suspension geometry. These cause excessive car tire wear, braking instability and poor handling. This is the single biggest reason you can immediately tell the difference between driving a three year old car and a new one. By using application specific polyurethane compounds, mount and bushings can be made 25-30% harder than rubber ones but with exactly the same shock absorbing properties.
