The POLEA 220 2B is an EMMAR-brand industrial pulley that MR Industrial Accessories LLC supplies for power transmission setups. It measures 220 mm in diameter and carries two grooves cut for section B belts. That combination suits drives where motion has to move from one parallel shaft to another, and it lets two belts share the work at the same time.
Reading the designation is straightforward: 220 is the diameter in millimeters, 2B means two grooves in section B. Section B is a classic belt profile used for medium power and moderate speeds. With two grooves, you can run two belts side by side, which spreads the torque and gives you a fallback if one belt gives out. The 220 mm diameter, together with the driving pulley, sets the ratio for the driven shaft. This pulley is made in-house under the EMMAR brand.
You will find this size on machine tools, compressors, pumps, fans, conveyors and process equipment. It fits situations where a motor turns a working shaft at a fixed ratio, and where dust, vibration and changing loads are part of the daily routine. Maintenance crews often keep this profile on hand because alignment and belt tension are easy to check and correct.
Before ordering, confirm the pitch diameter, groove count and belt section against the machine data. Check that the bore and keyway match the shaft you are mounting it on. When installing, line up the pulleys accurately so the belts do not wear unevenly. Set tension carefully: too loose and the belts slip, too tight and the bearings take unnecessary load. The machine manual is the final word on those settings.
If you need a different diameter, groove count or section, MR can manufacture it or locate an equivalent. Send the part number POLEA 220 2B, or the designation of the pulley you are replacing, by WhatsApp or email. The team also handles bearings, housings and other transmission parts, and can help you confirm the section or diameter when the markings are unclear.

Frequently asked questions
- What does the '2B' in POLEA 220 2B mean?
- The '2' is the number of grooves and the 'B' is the belt section. So this pulley takes two section B belts. Running both belts lets you transmit more torque and keeps the drive going if one belt fails.
- Can I run only one belt on a two-groove pulley?
- Yes, a single belt will work, but you lose the extra capacity and the backup. Using both grooves is the normal way to get the full benefit of the design.
- How do I ask for a different size or section?
- Send the diameter, number of grooves and belt section you need by WhatsApp or email. If you have the original pulley part number, include it. MR will quote a custom pulley or suggest an equivalent.
