Derailleur bearings are key components in the bicycle 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 crucial role in reducing friction and ensuring smooth gear shifting.
High-quality derailleur bearings can provide stable gear shifting performance, reduce energy loss, and improve cycling efficiency. They should possess durability, low friction, high load capacity, and excellent smooth rotation characteristics.
Transmission bearings are primarily 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.
