Many friends have doubts and do not believe that a transmission axle bicycle can last for 13 years. Today, the editor will answer why Space Cardan's transmission axle bicycle has a long service life.

Firstly, the most important components of a bicycle include the frame, transmission shaft, flower drum, gearbox, and other components, and the service life of the transmission shaft determines the service life of the entire vehicle.The outer shell of the Space Cardan drive shaft is made of aviation grade 6061 aluminum alloy, and heat treatment is also performed to enhance its hardness.

2. There are two small gears engaged and rotating inside, and the gear is made of 45 # steel casting material. The gear part is a strong force bearing part and must be durable. The groove of the gear must be precise to within 2 threads.

To ensure a longer service life, we also choose Japanese imported synergistic grease, which is thicker than domestic grease and has a service life three times that of domestic grease.
Space Cardan has 25 years of production and export experience in the driveshaft bicycle industry, with a mature production line for driveshaft bicycle products and a production team of over 10 years of engineers to create high-quality driveshafts for you. After undergoing full inspection and testing by quality inspection engineers, it is handed over to the customer to ensure their interests to the greatest extent possible.
