The 80 3B pulley is an in-house manufactured power transmission pulley, EMMAR brand, with 80 mm diameter, 3 grooves and section B. It is used to transmit motion between shafts using V-belts, in machines and equipment that require defined transmission ratios. Its construction seeks a balance between strength, alignment and uniform belt wear. If you need a pulley for replacement or for a new development, this model can be your starting point.

This pulley has 80 mm diameter, 3 grooves and section B. Section B corresponds to classic profile V-belts, and the three grooves allow mounting three belts in parallel on the same disc. The 80 mm diameter defines the transmission ratio when combined with another pulley in the same system. It is an in-house manufactured part, EMMAR brand, designed for applications requiring a compact pulley with capacity for multiple belts.

Typical applications include machine tools, pumps, fans, compressors and transmission equipment in general. It is also used in production lines and in agricultural or road equipment where power must be transmitted between shafts with section B belts. Having three grooves, it supports configurations with higher transmission capacity or redundancy, depending on the number of belts mounted. It is an alternative to replace worn pulleys or to build a new system.

To correctly select this pulley, take into account the pitch diameter, the number of grooves and the belt section. Verify that the shaft where it is mounted has the adequate diameter and keyway, and that the pulley is aligned with the driving pulley to avoid uneven wear. Section B requires belts of that profile; do not mix different sections in the same system. If the pulley will operate at high revolutions, it is advisable to check balancing and groove condition.

If you need a pulley with a different number of grooves, another diameter or a different section, we can manufacture it or find an equivalent. To do so, send us the part number POLEA 80 3B or the original pulley designation via WhatsApp, along with the equipment data: shaft diameter, belt section, number of grooves and center distance. With that information we will quote the option that best suits you. We can also advise you if you don't have the designation at hand.
