Description
EMMAR 20-B1 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 20-B1 and any equivalents.
The 20-B1 is a single-strand roller chain built to the European BS standard, with a 1 1/4-inch pitch, 19.05 mm rollers and 19.56 mm inner width. It links parallel shafts in industrial drives and works as a standard, replaceable part. MR Industrial Accessories supplies it for new drives and for replacement, and can help you confirm the right chain for your equipment.
The 20-B1 code tells you two things: the 20 series sets the 1 1/4-inch pitch, and the B1 suffix means a single strand. Roller diameter is 19.05 mm and inner width is 19.56 mm. That combination puts it in the medium-to-high power transmission range. Use it with sprockets of the same BS standard and pitch.
You will find this size on agricultural machines, conveyors, lifting equipment, mixers, mills and general production lines, as well as on pump, compressor and fan drives. Its roller construction handles moderate speeds and variable loads when installation and lubrication are right. It is a frequent choice where a European standard chain with good wear resistance is needed.
Selection comes down to pitch, sprocket tooth count, center distance and the power being transmitted. Check that the sprockets match the BS standard and the 1 1/4-inch pitch. During installation, align the shafts and set tension correctly: too tight and the rollers and bushings wear faster, too loose and the chain can jump. Lubricate on a regular schedule to get the most from the assembly.
If you need an equivalent, send the 20-B1 code or the measurements of your current chain: pitch, roller diameter, inner width and number of strands. We can also identify the chain from a sample or from the sprocket dimensions. MR Industrial Accessories works in power transmission and will guide you to the right chain for your application.

Frequently asked questions
- What does BS standard mean for this chain?
- BS (British Standard) fixes the pitch, width and roller dimensions. That makes the chain interchangeable with sprockets and chains of the same standard and pitch, which simplifies replacement in equipment already using that standard.
- How do I check if this chain fits my sprocket?
- Confirm the sprocket is made for a 1 1/4-inch pitch BS chain. Also check the number of teeth and the pitch diameter. If you are unsure, send us the sprocket measurements and we will confirm compatibility.
- What lubrication should I use?
- Use oil or grease with a viscosity suited to the operating speed and temperature. How often you lubricate depends on the environment: in dusty or high-temperature applications, lubricate more frequently and inspect for wear.
