EMMAR 12-B2 roller chain

EMMAR 12-B2 belongs to roller chain, part of our Power transmission range. Tell us how many you need by WhatsApp or email and we'll get back to you promptly with a quote for 12-B2 and any equivalents.

The 12-B2 is a BS-series roller chain with two strands, built to the European standard and running on a 3/4 inch pitch. It handles power transfer between parallel shafts when a single row of rollers would not be enough for the demand. MR Industrial Accessories quotes this chain by part number through WhatsApp or email, and the team can also propose equivalent options if you send the details of your drive.

Look at the code first: 12 sets the 3/4 inch pitch, B identifies the roller chain family, and the 2 tells you there are two strands. Roller diameter is 12.07 mm, and the space between the inner plates measures 11.68 mm. Because two rows of plates and rollers sit side by side, the chain carries more load than a single-strand 12-B of the same pitch while staying within one sprocket width.

Typical applications include agricultural machinery, conveyors, bucket elevators, mixers and process lines. It also suits low-speed, high-torque drives where a single-strand chain is working at its limit, and machines where shaft space is tight and the load has to stay on one line.

Before ordering, confirm the pitch matches your sprockets and that the 11.68 mm inner width fits the tooth thickness. Double-strand sprockets are required; a single-strand sprocket will not mesh. Check shaft alignment and tension as well, since a misaligned double-strand chain wears rollers and plates quickly. Follow the lubrication schedule for the duty cycle and inspect for elongation at regular intervals.

To get a quote, send the code 12-B2 along with pitch, number of strands, and a photo or sketch of the sprocket. The team can also point you to the single-strand 12-B or another pitch in the same BS series, and will reply with the option that fits your machine.
