OOB-10 Dry Bearings Steel+Bronze Powder+PTFE Layer

Product Overview:Apply to the oil or fuel work harder parts,wear resistance.low coefficient of friction,long life;good overall performance.Apply to the oil or fuel work harder parts,wear resisrance.low coefficient od friction,long life;good ocverall performance.

PTFE lined selflubricating bearing also called DU bushing, dry bushing, DU bearing,teflon bushing,

PTFE coated bearing,SF1 oilless bearing and PTFE based plain bearing.

This type of DU bush takes PTFE layer as sliding layer which makes products

can perform very well under dry condition or oil condition.

OOB-10 bushes are produced in a lightweight, compact material with minimum bulk, simplifying shaft assembly. Featuring high-level chemical resistance, OOB-10 shafts can be covered or plated with materials resistant against chemically aggressive liquids, gas or solids, through the application of an additional galvanic layer. This type of bush does not require lubrication and its operating temperature is between-195°Cand +280°C.


As they do not absorb oil and water, OOB-10 bushes have a low expansion  and high conductivity rate, as well as good thermal stability. Furthermore, by using this type of bush, vibrations, noise and pollution are significantly reduced.

Special technical features

OOB-10 bushes present good fluidity and a low coefficient of static and dynamic friction (no stick-slip effect). In addition, thanks to the balanced distribution of the load on wide elasto-plastic surfaces, this type of bush has a high load capacity, equal to 140 N/mm2.

Dual mass flywheel Bearing self-lubricating bearing oilless bearing bronze bushing china factory china supplier repair dual mass fly wheels vehicles bearings

What is a Dual Mass Flywheel?

A Dual Mass Flywheel (DMF) is a type of flywheel where the rotating mass is split between two independent pieces. These two plates are joined by a damping mechanism to dampen torsional spikes and vibration generated through the crankshaft. This allows for a smoother and more enjoyable driving experience. They generally work well as long as the engine remains unmodified and the vehicle is not used beyond manufacturer's recommendations. As soon as you start to increase the engine power over stock, or load the vehicle or a trailer beyond the vehicle design specifications, overloading will occur.

Dual mass flywheels are tuned to match the engine torque curve, engine resonant vibration characteristics, and vehicle load curves. They work by having a set of springs inserted between two rotating masses (i.e. Dual Mass). The springs are designed to absorb the resonant vibration from the engine before it transfers to the transmission. The dual mass flywheel contains an excessive "Friction Torque Limiter" so that if the flywheel is suddenly overloaded, it is designed to start slipping rather than damage the springs. This works fine as an occasional safety valve, but if occurs too often, it can overheat and burn up. Dual Mass Flywheels are not a good fit if the vehicle is overloaded, exceeds towing limits, or the engine is modified to produce increased horse power over the OE Specifications.

Dual mass flywheels are designed to provide maximum isolation of the frequency below the engine's operating RPM, usually between 200-400 RPM. They are also most effective during engine startup and shutdown.

A typical dual mass flywheel consists of 5 components:

1. Primary Flywheel 

2. Secondary flywheel 

3. Arc Damper Spring 

4. Friction Torque Limiter 

5. Ring Gear

Center Bearing 

A sealed double row center ball bearing carries the load between the inner and outer halves of the DMF. The leading cause of center bearing failure is often related to out of balance vibration caused by not aligning the pressure plate with the DMF dowel pins. The center bearing may also fall if the clutch pilot bearing is destroyed by a worn transmission input shaft (see Pilot Bearing) or if the rated load/towing capacity of the vehicle is exceeded.

Pilot Bearing 

The pilot bearing supplied with most DMF's is a caged needle roller bearing. If it fails, the transmission input shaft must be repaired or replaced. If the input shaft is not repaired correctly or replaced, the lack of input shaft support will result in DMF center bearing failure.

Self-Lubricating Bearings for Automotive Applications

Auto design manufacturers are constantly seeking new solutions to help improve the safety and performance of their vehicles.  Innovations in 4-wheel drive controls, CVTs (continuously variable transmissions), clutch systems and dual-mass flywheels are helping to meet those goals.  But these components have also increased the demand for heavy-duty sliding, oscillating and rotary bearings. OOB bearings are designed to excel in automotive applications:

Dual-layer design gives many options for outer-shell structural support and polymer liners

Self-lubrication gives manufacturers maintenance-free design options

Exceptional capacity for tolerating side loads

PEEK/Stainless bearings are an excellent substitute for applications in high temperature chemical valves and pumps.

Good vibration resistance for auto undercarriage components
