Rubber bushings are a primary material that automotive manufacturers use in order to reduce the transmission of shock and vibration between parts. In other words, rubber bushing is the material used on shock absorbers that minimizes noise and damage due to reduced vibration. Moreover, it increases comfort and safety when driving. In this post, we have compiled a list of some of the most interesting as well as pertinent facts about rubber bushings that you may not know.

Rubber Bushings Were Invented in the 1930s

Walter P. Chrysler is credited with the idea of using rubber bushing in the automotive industry in 1932. He reportedly encouraged the adoption of vibration-isolating mounts made from rubber to reduce the noise and vibration of vehicles.

Since then, rubber bushings have been used in several vehicle components that usually produce a lot of noise and vibration. Today, shock-absorber mountings made from rubber are the industry standard among commercial vehicle and automotive manufacturers.

For the uninitiated, vibrations – when left unaddressed – cause a lot of damage to products. Also, they generate loud noises that are not only comfortable but also potentially dangerous to operators. Bushings made from rubber absorb all this noise and vibration.

Rubber Bushings Are Actually Made of Rubber, Polyurethane, and Other Materials

Shock mounts or bushings are cushions made of polyurethane, rubber, and metals – and not just rubber. In fact, these cushions are extremely effective in controlling the amount of movement in steering joints and car suspensions to absorb road bumps and diminish vibration and noise. The rubber used to make these mounts is vulcanized and bonded. Aluminum, stainless steel, and mild steel are the most common metals used in the process.

Rubber Bushings Are Suitable For All Types of Vehicles

Uniflex Inc.’s rubber bushes are perfect as mechanical joints on rail and road vehicle suspensions, captive cab mountings, gearbox mountings, engine mountings, and pivot arms. The rubber on shock absorbers plays a vital role in vehicle comfort and safety when driving, used for aligning and positioning steering and suspension parts.

These include torsion bars, control links, sway bars, and shock absorbers, of course. Rubber bushings must remain in robust condition to prevent rapid tire wear and issues with steering. In addition to shock absorber mountings, rubber bushings are perfect for gear sticks (in vehicles with manual transmissions) and double wishbone suspension assemblies.

 Several Industries Use Rubber Bushings

While we have mostly discussed their usage in the automotive industry, many other industries and applications use rubber bushings as well, such as:

  • Aerospace
  • Drilling equipment
  • Highway equipment
  • Construction
  • Plumbing
  • Electrical
  • Specialized internal combustion engines
  • Bikes and skateboards
  • Consumer appliances and goods
  • Sealing applications (for tubes, pipes, and wires)
  • And more!
