Bushings cars.

In automobile suspensions or other vehicles, and bushings for connection of various components in motion and pivot with the chassis and other suspension systems. To reduce vibration, wear and deterioration due to noise emission, usually incorporate a portion of flexible material such as rubber or polyurethane. Such bushings are usually cylinder shaped ring of a flexible material on the inside of an outer tube. May also have an inner tube to prevent the flexible material from being crushed.

There are many kinds of designs.

Another kind of hub is having a hardened threaded hole that lets a coupling is attached to another by a screw. Using a bushing makes the assembly process is easier, it eliminates the need for the washer and nut on the other side of the material to set.

Bushing bicycles.

Bushings on a bike can be distinguished by its turning system class, which may be sealed bearings or spheres. The field system is an old system, yet is still used in some brands due to its high efficiency, with the drawback that gets dirty easily and the setting operation is complicated. Furthermore, the sealed bearings are almost completely watertight and have greater stiffness, although heavier.

The hub flange is a part that suffers spoke tension wheel.

Bushing vanes.

The hub of a fan component which is located the fan blades, which also supports the rotor and the outer rotating fan.

It is a very important piece in wind turbines. Have systems that let you change the pitch of the helix, consisting of hydraulic, electrical, allowing the blades rotate from zero to ninety degrees, which is the stop condition. Are attached to the hub-called blade bearings that reduce the friction when rotating the blades.

Most of which use turbines manufactured steel for construction of the bushings, using different alloys according to the temperature, humidity, wind, etc..

The current wind turbines, which are capable of producing 1.5 to 2 MW, typically have a weight counting all elements of a fifteen to twenty tons.
