What is the difference between A-chain and B-chain

The difference between Roller Chain a and b series and identification of chain size Precision roller chain is divided into two series, A and B. The A series is the size specification that meets the American chain standards: The B series is the size specification that meets the European (mainly British) chain standards. Except for the same pitch, there are other characteristics of this series

The tension difference is: the thickness of the inner link plate and the outer link plate of the A series products are commensurate with each other. B series products are commensurate with the inner link plate and the outer link plate. Baidu, which has decided on the difference, has obtained equal strength results of static strength.

The tension size and pitch of each element of the A series have a certain proportion. Such as: pin diameter = (5/16) P, roller diameter = (5/8) P, chain plate thickness = (1/8) P (P is the chain pitch), etc. However, there is no obvious ratio between the tension size and the pitch of the B series parts.

The specific load of the chain breaking load of the same Gear, except for the 12B specifications of the B series, which are lower than the A series, the specifications of all other gears are the same.

This product standard equivalently adopts the international standard ISO9606: 1994, and its product specifications, dimensions and pull load values are completely consistent with international standards.

Layout features: The chain consists of an inner link consisting of an inner link plate, rollers and sleeves, and an outer link consisting of an outer link plate and a pin.

Product selection can select the required chain specifications according to the power curve. If selected according to the strategy, the quietness coefficient should be greater than 3.
