EMMAR POLEA 380 6B belongs to pulleys, 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 POLEA 380 6B and any equivalents.

The 380 6B is a V-belt drive pulley from EMMAR, designed for power transmission between parallel shafts. It measures 380 mm in diameter and has 6 grooves for section B belts. Typical uses include fans, compressors, pumps, conveyors, and production machinery. Because it is manufactured in-house, the bore, keyway, and balancing can be machined to match your equipment's shaft. To request a quote, send the part number by WhatsApp or email.

This pulley is defined by three key figures: a 380 mm diameter, 6 grooves, and section B. Section B is a narrow-pitch V-belt profile suited to medium power and moderate peripheral speeds. With six grooves, the load is shared across multiple belts, which lowers the stress on each belt and helps maintain drive continuity if one belt fails. The 380 mm diameter determines the transmission ratio when paired with the driven pulley. As an in-house manufactured part, the bore and keyway are machined to match your shaft dimensions.

Six-groove section B pulleys are common in equipment that runs continuously and needs some reserve capacity: industrial fans, screw compressors, centrifugal pumps, conveyor belts, mixers, and machine tools. They also serve as replacements for worn or cracked pulleys on production lines. The multiple-groove design is often chosen for drives where reducing vibration and slippage matters, or where the process must keep running even if a single belt breaks.

When mounting, confirm that the bore and keyway fit the shaft. The pulley is secured with a key and, depending on the setup, a set screw or taper bushing. Align the pulleys with a straightedge or laser so the belts run parallel and do not wear unevenly. Adjust belt tension according to the equipment manual: too little tension causes slippage, while too much loads the shaft bearings. For high-speed operation, the pulley should be balanced. We can machine the bore, keyway, and balancing to your equipment data.

If you need an equivalent to the 380 6B, send the complete part number, the equipment brand, and a photo of the part. With that information we can confirm whether the in-house manufactured pulley matches in diameter, grooves, and section. We can also produce a custom pulley if the shaft or keyway is non-standard. For that, provide the shaft diameter, bore length, and number of grooves. Quotes are handled via WhatsApp using the part number MR-POLEA-B6-380 or the designation POLEA 380 6B.
