WHAT ARE BUSHINGS ON A CAR?
Bushings also called flexible or anti-vibration mountings, allow parts to move without transmitting vibration to the cabin. Limited-motion joints, like control arms and sway bar links, usually use bushings. Bushings are also used in non-moving parts, such as body mounts and strut mounts.
Some bushings are filled with oil, and others may be molded to be softer or harder in one direction. The simplest bushing consists of a metal inner sleeve bonded to an outer metal sleeve with rubber. On control arms, like those in the front end, the outer sleeve is pressed into the control arm, and a bolt affixes the inner sleeve to the frame. Neither sleeve moves, but the flexible rubber allows a limited range of motion between them. Rubber doesn’t transmit vibrations well, which prevents them from reaching the cabin.
TIPS FOR REPLACING BUSHINGS
Body mounts, engine mounts, sway bar bushings, steering rack bushings and sway bar link bushings are usually replaceable without special tools. Some control arm bushings are available separately, but special tools are required. Some control arm bushings are not available separately and require a whole new control arm. Bushings that improve performance are also available in the aftermarket. For example, stiffer bushings can reduce body roll and improve stiffness.
When replacing bushings, two factors are important: First, pay close attention to the depth and orientation of pressed-in bushings. Bushings that are pressed in too shallow or deep can lead to interference and noise, and certain bushings need to be installed in a specific orientation for consistent performance. Second, for control arm, sway bar, shock and strut bushings, tighten all fasteners with all four wheels on the ground. This will prevent preloading the suspension, which can mimic alignment problems.
While bushings are a simple component, replacing them can significantly improve the quality of your ride. Whether you’re replacing bushings for wear or as an upgrade, you can enjoy a quieter and stiffer ride in just a few hours.
What Are Bearings? Let's learn about the basic functions of bearings!
Bearings are "parts that assist objects' rotation". They support the shaft that rotates inside the machinery.
Machines that use bearings include automobiles, airplanes, electric generators, and so on. They are even used in household appliances that we all use every day, such as refrigerators, vacuum cleaners, and air-conditioners.
Bearings support the rotating shafts of the wheels, gears, turbines, rotors, etc. in those machines, allowing them to rotate more smoothly.
In this way, all sorts of machines require a great many shafts for rotation, which means bearings are almost always used, to the point where they have become known as "the bread and butter of the machine industry". At first glance, bearings may seem like simple mechanical parts, but we could not survive without bearings.
Bearings play a crucial role in our daily lives, but it is precise because of their importance that we must constantly strive to make them more precise and durable.
Additionally, it is vital to the development of machine technology that we continue going forward to develop bearings that can work under ever harsher and more specialized conditions.
Bearings will no doubt continue to evolve and change, and improve our livelihoods by "making the world go round".
