The EMMAR 170 3B is a V-belt drive pulley built for parallel-shaft power transmission. Its designation covers the key specs: 170 mm diameter, 3 grooves, section B. Because EMMAR produces it in-house, construction and machining options can be reviewed for your specific drive.
This pulley carries the code POLEA 170 3B, which packs three details into one string: the outside diameter in millimeters, the groove count, and the belt profile. Section B matches classic V-belts of that profile, and the three grooves let you run three belts side by side to raise transmission capacity. Grooves are machined to the tolerances required for proper belt seating.
Typical applications include fans, centrifugal pumps, compressors, conveyor drives, mixers, and machine tools where shafts run parallel. The pulley is often used to step motor speed up or down to the driven shaft. In maintenance work, it also serves as a replacement when a worn pulley must be swapped out or the existing ratio needs to change.
When selecting a pulley like this, confirm the pitch diameter, groove count, belt section, and the keyway or bushing style your shaft uses. During installation, check pulley alignment and belt tension; misalignment speeds up wear on both belts and bearings. If the shaft has a keyway, verify that the hub size matches.
Need a different groove count, diameter, or section? EMMAR can manufacture it or help you find an equivalent. Just send the part number POLEA 170 3B or the original pulley data: diameter, grooves, section, and mounting type. With that, we will quote the option that fits your equipment, whether it comes from our own production.
