Product Description
Composition
Derailleur bearings are important sections in the bike derailleur system, used to support and enable smooth rotation of the derailleur pulleys. They bear the load of the derailleur and the tension of the chain, playing a key part in reducing friction and ensuring smooth gear shifting.
|
Features
Good derailleur bearings offer stable gear shifting performance, reduce energy loss, and improve cycling efficiency. They should equip with durability, low friction, high load capacity, and excellent smooth rotation characteristics. |
Application
Transmission bearings are marjorly used in bicycle transmission systems.
Transmission bearings bear the tension of the chain and the load of the transmission during gear shifting, ensuring the proper operation of the transmission.
