The EMMAR 270 1B is a V-belt pulley with a 270 mm diameter, one groove, and section B. It transmits motion between parallel shafts in industrial machinery where a straightforward, dependable speed ratio is required. Because we manufacture it ourselves, we control the machining and finish so it mounts cleanly on the shaft and keeps the belt properly seated.

The part number POLEA 270 1B tells you the three key attributes: 270 mm diameter, 1 groove, and section B. Section B refers to the V-belt profile the groove accepts, a common choice in industrial drives. The groove is machined so the belt sits evenly and stays in place during operation.

You will find this pulley on fans, pumps, compressors, conveyors, and machine tools driven by electric motors, where the driven shaft speed needs to be raised or lowered. It is also a routine maintenance item on production lines, replaced when a groove wears or when the ratio changes. A worn or misaligned pulley causes vibration, noise, and early belt failure, so checking it during service pays off.

During installation, confirm that the shaft diameter matches the bore and that the key fits without play. Align the pulley with the drive pulley; even a few degrees of misalignment speeds up belt wear. Set tension per the equipment manual or the belt manufacturer's guidance. For high-speed operation, consider checking balance. When selecting a replacement, account for the power to be transmitted, the speed, and the number of grooves required.

If you need a different diameter, groove count, or section, we can manufacture it. Send the part number POLEA 270 1B or the original pulley data—diameter, grooves, section, and bore—and we will quote an equivalent. We can also discuss machining the bore and keyway to match your shaft. The more details you provide, the faster we can respond.
