What is DU bushing?
DU® self-lubricating split bushings offer very good wear and low friction performance over a wide range of loads, speeds and temperatures in dry running conditions. Bushing material suitable for lubricated applications. Anti-friction bearing suitable for linear, oscillating and rotating movements.
What is a DU bearing?
The structure of the bearings consists of a rigid steel or corrosion-resistant bronze backing (DU-B), which provides mechanical strength, while a porous sintered bronze interlayer impregnated with a homogeneous mixture of PTFE and lead provides low friction and high wear resistance.
What are the different types of bushing?
Bushing Types & Material – Overview
- The Self-Lubricating Bushing Concept.
- Metal-Polymer Composite Bushings (Plain Bearings)
- Bronze Wrapped Bushings.
- Filament Wound Plastic Self-lubricating Bushings.
- Injection Molded Plastic Self-lubricating Bushings.
Which material is used for bushing?
Bushings are typically made from porcelain; though other insulating materials are also used.
What is DU sealed bearing?
DU bearings are “sleeve” bearings (a hollow cylinder with no balls) made of high tech materials. They are typically impregnated with Teflon so that they don’t need additional lube. They are not inherently “sealed” but they tolerate dirt better than ball bearings.

Why is it called a bushing?
bushing (n.)
“metal sleeve fitted into a machine or hole,” 1839, from gerundive of bush (n.) “metal lining of the axle hole of a wheel or touch hole of a gun” (1560s), which is from Middle Dutch busse “box” (cognate with the second element in blunderbuss).
Why bush is used in bearing?
Bushings, also called sleeve bearings, are just one specific type of bearings. They are made to slide over rods to provide an extremely low-friction motion. They are excellent for shock absorption and work to minimize energy usage, noise, and wear.
What type of rubber is used in bushings?
Styrene Butadiene Rubber (SBR)
SBR is the oldest and most widely used type of synthetic rubber due to its excellent mechanical and elastic properties. It is an ideal material for the manufacture of rubber bushings since it is capable of withstanding the wear and stress demanded of bushings.
Why is brass used for bushings?
Brass applies to the shaft bushing because of its anti-rust properties, along with its anti-friction properties when in contact with steel. A rubber seal is placed on the inside part of the bushing to prevent water leakage. This seal allows a minute amount of fluid to leak through to lubricate the bushing.
What is DU bearing vs sealed bearing?
Are double DU a form of sealed bearings? DU bearings are “sleeve” bearings (a hollow cylinder with no balls) made of high tech materials. They are typically impregnated with Teflon so that they don’t need additional lube. They are not inherently “sealed” but they tolerate dirt better than ball bearings.
Why do Shimano use cup and cone?
Angular contact bearings of the cup & cone type offer greater strength than sealed cartridge industrial bearings due their ability to displace lateral and vertical loads more effectively for super smooth rotation and longer durability.

Can you replace bushings on a shock?
Often made from steel with a nylon / PTFE coating, the bushings inside the eyelets of your rear shock are designed to wear over time, and thus – they are an easily replaceable part with the right tools and a little care.

Are bushings better than bearings?
There isn’t really a difference: a bushing is a type of bearing. In general, a “bearing” facilitates movement between two parts while reducing friction. Simple in design, the typical bearing has two surfaces that roll over each other, enabling two mating components to move friction-lessly.
What is better bushing or bearing?
Bearing advantages
The motion provided by bearings is generally smoother than bushings, overcoming static friction by rolling instead of sliding. They tend to be more precisely built with tighter tolerances for a better fit than bushings, reducing sloppiness and backlash.
Is polyurethane bushings better than rubber?
Ride Quality: Because rubber is softer than polyurethane, it’s much better at warding off road noise and vibrations. This means that rubber bushings make for a much smoother ride. This is one of the main reasons—aside from cost–that OEMs use rubber ones on the assembly line.
How long should bushings last?
Bushings made of rubber would be designed to last about as long as rubber hoses, generally the lifespan expected would be about 15 years, which for most would be the life of the car. The environment they are in will affect the lifespan.
What grade of brass is used for bushings?
660
| Alloy Type | Description |
|---|---|
| 655 | Often used in marine environments because of its good corrosion resistance fromsalts, acids and alkalais. |
| 660 | Excellent impact and wear resistance. Excellent for bearings and bushings. |
| 954 | A popular aluminum bronze that has excellent strength and hardness. Good for usein pressure bearing surfaces. |
Which is better for bushing brass or bronze?
Bronze sleeve bushings or bronze bearings are hard and strong, as opposed to brass bushings, which are softer and more easily deform. Thus, bronze bushings have longer lifespans than brass bushing sleeves. They resist shock and impact, wear and corrosion.
Is Du bearing sealed?
