When a single-strand chain runs out of capacity but the pitch must stay the same, the 10-B2 double-strand roller chain is the usual answer. It follows the European BS standard and measures 5/8 inch pitch, with a roller diameter of 10.16 mm and an inner width of 9.65 mm. MR Industrial Accessories LLC supplies it to maintenance and purchasing teams across the United States and Latin America for drive building, equipment replacement and routine industrial maintenance.
The 10-B2 carries two rows of rollers side by side. That second row doubles the number of contact points with the sprocket teeth, so the chain can move more torque than a single-strand chain of the same pitch. The condition is simple: the sprocket must be made for two rows. A single-row sprocket will not accept it.
You will find this chain in low- and medium-speed drives where space is tight but the load is not: conveyors, mixers, mills, chain elevators, and drives on agricultural and industrial machinery. It is also a common upgrade when a single-strand chain is swapped for a double one to gain capacity without touching the pitch or the transmission ratio.
Selection comes down to three checks. Confirm the pitch matches the sprocket, confirm the number of rows is correct, and confirm the roller and inner width match the old chain. From there, lubrication and shaft alignment decide how long the drive lasts. In dusty conditions or where lubrication is poor, inspect pitch elongation and sprocket wear before replacing the chain alone.
To quote an equivalent, send the part number 10-B2 or the full designation from the equipment nameplate. A photo of the chain and the sprocket also works. With that information the team verifies the series, the pitch and the number of rows, and can suggest equivalents or help you choose the right chain for the drive.

Frequently asked questions
- What does the "B2" in 10-B2 mean?
- The B indicates the European BS series, and the 2 indicates two strands, meaning two rows of rollers running in parallel. It is not interchangeable with a single-strand chain unless the sprocket is also changed to a two-row type.
- How do I confirm the 10-B2 is the right chain for my equipment?
- Check the pitch (5/8 inch), the roller diameter (10.16 mm) and the inner width (9.65 mm) against the old chain, and make sure the sprocket is two-row. If anything is unclear, send a photo of the chain and sprocket.
- Can I replace a single-strand chain with a 10-B2?
- Only if you also replace the sprocket with a two-row one. The double chain will not fit a single-row sprocket. If you need more capacity, ask and we will tell you which chain and sprocket are required.
