The dual mass flywheel bearing or bushing is a crucial component in the transmission system of many modern vehicles. Its main function is to connect the engine crankshaft to the transmission input shaft while effectively isolating engine vibrations from the vehicle's chassis and passenger compartment.

The dual mass flywheel consists of two rotating masses connected by springs and dampers, with the bearing or bushing located at the interface between the two masses. This design allows the flywheel to absorb and dampen engine torsional vibrations, reducing noise and harshness in the vehicle's cabin.

The bearing or bushing itself is a precision-engineered component made from high-quality materials, such as metal-plastic composites. It must be able to withstand the high loads and frequent rotations of the engine crankshaft while maintaining smooth operation and minimal wear.

Failure of the dual mass flywheel bearing or bushing can lead to various symptoms, including increased vibration and noise in the cabin, poor transmission performance, and even damage to other transmission components. Therefore, it's important to inspect and replace these components regularly as part of routine vehicle maintenance.

In summary, the dual mass flywheel bearing or bushing plays a vital role in ensuring smooth and reliable transmission operation while minimizing engine vibrations in modern vehicles.

Improve quality and environmental standards
Our environmentally friendly, lead-free bearings reduce installation, operation, and maintenance costs.

• ROLLED DRY SLIDING BEARINGS (PTFE)

• Steel + Bronze Powder + PTFE/Fibre

• Wrapped PTFE Lined (maintenance-free), self lubricated plain or flanged bearings, thrust washer and strip, Carbon steel shell with sintered bronze layer filled with PTFE

VSB-10 Self-Lubricating Multilayer Composite Bushing

• Bushing material suitable for lubricated applications

• self-lubricating bushings offer very good wear and low friction performance over a wide range of loads, speeds and temperatures in dry running conditions

• Anti-friction bearing suitable for linear, oscillating, and rotating movements 

• Material is designed to operate without supplemental lubrication and will perform excellent when lubrication is present. Low friction, low wear rate, good sliding characteristics and very low absorption are a few of the features of this material. VSB-10 bushings will support the rotary, linear and oscillating motion.

 
1. PTFE/Fibre mixture thickness 0.01~0.03mm. It is the contact surface for the rotating shaft. Minute partides of the PTFE layer and the sintered bronze material combine to create a solid lubricant film, which coats the shaft.
 
2. Sintered bronze powder thickness 0.20*0.35mm,A special composition of powdered copper is thermally fused to the steel backing. This contact layer acts as an anchor for the PTFE layer and conducts the thermal build up away from the bearing surfaces.

3. Low-carbon steel backing. Setting the foundation of the bushings, the steel back provides exceptional stability, load carrying and heat dissipation characteristics.

The main factors affecting the life of self - lubricating bearings

1: load P: the greater the load, the shorter the service life of the bearing;Under no circumstances shall the maximum load exceed the theoretical maximum allowable load.
2: speed V: the higher the speed, the shorter the service life of the bearing;Under no circumstances shall the maximum sliding speed exceed the theoretical maximum allowable value.
3: PV value: the working life of the bearing depends on the PV value, that is, the product of the actual load P and the sliding speed V. The smaller PV value is, the longer the bearing life is.
4: temperature: the life of the bearing also depends on the temperature when the bearing is in use, the higher the temperature, the shorter the life of the bearing, so in the design and selection should try to consider the heat dissipation characteristics of the relevant parts.
5: surface roughness of the grinding parts: alloy steel or hard chromium plated shaft is used for the grinding parts. When the surface roughness Ra=0.4-0.63, the service life of the bearing can be significantly improved.
6: other factors such as bearing design, lubrication conditions, etc
