What is the model number of the roller chain?

[DiCecilia]

The model number of the roller chain is 06B roller chain. Roller chain: An external roller chain refers to a chain with rollers on one or both sides. These side rollers can be installed either alternately or side by side at given intervals to ensure high-speed and smooth operation of the chain. Transmission chain: Transmission chains are divided into Series A and Series B. Series A conforms to the size specifications of American chain standards, while Series B conforms to the size specifications of European chain standards. The difference between the two chains is minimal. In Series A, the rollers and pins have a certain proportional relationship, whereas in Series B, the main dimensions of the components do not have an obvious proportional relationship with the pitch. Except for the 12B specification, which is lower than the A series, the other specifications of Series B are equivalent to the corresponding Series A products. In reality, these differences are not significant, but it is important to note that when selecting a chain for safety, the applied torque must be at least three times the limit torque.
