The 12-B1 is a single-strand roller chain built to the European BS standard, featuring a 3/4-inch pitch. It connects parallel shafts to transfer power in industrial machinery, offering dependable operation and straightforward upkeep. MR Industrial Accessories supplies this chain as part of its power transmission range, alongside sprockets, tensioners, and lubricants. Whether you are replacing a worn chain or designing a new drive, just send the part number and our team will get back to you with a quote.
This chain carries the 12-B1 designation, which tells you it is a British Standard (BS) roller chain with a 3/4-inch pitch and a single strand. The rollers measure 12.07 mm in diameter, and the inner width between the link plates is 11.68 mm. In the code, 12 indicates the size, B denotes the British series, and 1 means single strand. Made of steel, it is intended for power transmission between parallel shafts.
You will find the 12-B1 in many industrial settings: belt and roller conveyors, elevators, mixers, mills, machine tools, and packaging lines. It also appears in agricultural equipment such as seeders and harvesters, as well as in aggregate processing plants. Its sturdy build and standardized pitch suit conditions with dust, moderate humidity, and fluctuating loads, as long as lubrication and tension are maintained.
When choosing this chain, consider the power to be transmitted, the shaft speed, and the number of teeth on the sprockets. Because the BS standard fixes the dimensions, a 12-B1 chain can be swapped with another of the same designation. Make sure your sprockets match the 3/4-inch pitch and that the 11.68 mm inner width fits the sprocket groove. Proper installation requires aligned shafts and correct tension to avoid jumping and early wear.
