The 12-B2 chain is a double-strand roller chain according to European standard BS, with a 3/4 inch pitch. It is used to transmit power between parallel shafts when more load capacity is needed than a single-strand chain of the same pitch.

This item is a double-strand roller chain from the BS series, identified as 12-B2. Its rollers have a diameter of 12.07 mm and the inner width between plates is 11.68 mm. The pitch is 3/4 inch, the same as the single-strand chain 12-B. The double strand doubles the number of plates and rollers per pitch, which allows transmitting more power in the same sprocket width.

It is used in chain drives in agricultural machinery, conveyors, bucket elevators, mixers and process equipment. It also appears in low-speed, high-torque drives where a single-strand chain would be at its limit. It is commonly found in machines where axial space is limited and the load needs to be concentrated on a single shaft line.

To select it, check that the pitch matches that of the sprockets and that the 11.68 mm inner width is compatible with the tooth thickness. The double strand requires double-strand sprockets; a single-strand sprocket will not work. Check shaft alignment and tension: a misaligned double-strand chain wears rollers and plates quickly. Lubricate according to the operating conditions and check elongation periodically.

If you need a neighboring size or an equivalent, send us code 12-B2 along with the pitch, number of strands and a photo or sketch of the sprocket. We can also check whether a single-strand 12-B chain or one with a different pitch from the same BS series works for you. With that data, we will send you the alternative that best fits your machine.
