The 80 4B pulley is a power transmission pulley of in-house manufacturing, EMMAR Accesorios Industriales brand. It has 80 mm diameter, 4 grooves and section B, which makes it suitable for driving several shafts at once with a single belt. It is used in machines that need to synchronize speeds or distribute load between transmission lines. If you are looking for a compact pulley with good torque capacity and multiple grooves, this size is a concrete option for your equipment.

This pulley has 80 mm diameter, 4 grooves and section B. Section B defines the groove profile and the corresponding belt type; the 4 grooves allow mounting four belts in parallel on the same disc. The 80 mm diameter places it among the small pulleys in the line, designed for transmission ratios where the driving shaft rotates faster than the driven one. It is a cast or machined part depending on the batch, manufactured by EMMAR, and is delivered with the bore to be defined according to the customer's shaft.

Typical applications are machine tools, compressors, centrifugal fans, pumps and low-power conveyors. It is also used in multiple-drive equipment where several belts need to work in parallel to distribute the load and reduce vibration. In process plants, this pulley appears in agitator and mixer drives. Having 4 grooves, it is common to see it in installations where a single belt cannot be allowed to take all the effort.

To mount it, verify that the shaft bore matches the pulley diameter and that the key fits without play. Align the pulley with the counter-pulley using a straightedge or an alignment laser: a misalignment of a few degrees accelerates wear on the belts and on the shaft bearings. Belt tension is adjusted according to the equipment manual; in 4-groove drives, all must have the same tension so they work evenly. Check balancing if the pulley will rotate at more than 3000 rpm.
