The 330 1B pulley is a power transmission pulley of in-house manufacturing, EMMAR Accesorios Industriales brand. It is designed to mount on shafts and transmit motion via a section B V-belt. Its 330 mm diameter and single groove make it suitable for applications requiring a specific transmission ratio with a single belt. Since it is manufactured by EMMAR, dimensions and balancing are controlled for stable operation.

This item is a pulley of 330 mm diameter, with 1 groove and section B. The designation POLEA 330 1B summarizes those characteristics: the number 330 indicates the measurement in millimeters and 1B the number of grooves and the belt section. Section B corresponds to classic-profile V-belts, suitable for transmitting medium power over a wide range of speeds. The pulley is manufactured at MR with materials and processes that ensure concentricity and balance.

Typical applications of a pulley of this type include industrial machines, compressors, fans, pumps and transmission equipment in general. Having a single groove, it is used in simple drives where neither redundancy nor high power is required. It is common in installations where space is limited or where an economical solution is sought to transmit motion from a motor to a driven shaft.

To correctly select this pulley, take into account the pitch diameter, which must be compatible with the section B belt. Verify that the shaft has the appropriate diameter for the central bore, which may require machining according to the application. Mounting must ensure alignment between pulleys to avoid premature belt wear. If you need a pulley with more grooves or a different diameter, consult us.
