The pulley POLEA 90 1A is a V-belt drive pulley with section A, 90 mm diameter and a single groove. It is used to transmit motion between parallel shafts in industrial machines and equipment, where a simple and reliable transmission ratio is needed. Being in-house manufactured, EMMAR brand, the machining and balancing are controlled so that the belt seats well and the assembly runs without vibrations.

This item is a pulley with 90 mm diameter, 1 groove and section A. Section A corresponds to classic narrow-profile V-belts, and having a single groove makes it suitable for single-strand drives. The 90 mm diameter is the pulley pitch diameter, and the groove is machined so that the belt seats on the flanks, not on the bottom. It is a cast iron or steel part, depending on the batch, and is manufactured at MR with dimensional control.

It is used in equipment where power must be transmitted between a motor and a driven shaft: fans, pumps, compressors, conveyor belts, mixers and machine tools. It also appears in air conditioning installations and in low and medium power transmission systems. Due to its compact size, it is common in tight spaces where a larger diameter pulley does not fit. With a single groove, it is chosen when the power to be transmitted does not require multiple strands.

To mount it, verify that the shaft has the correct diameter and tolerance, and that the keyway matches. The pulley must be aligned with the drive pulley to avoid uneven belt wear. Tension is adjusted according to the equipment manual or standard practice: too loose slips, too tight stresses the bearings. If you are replacing an existing pulley, take the pitch diameter, number of grooves and section as minimum data to request the equivalent.

If you need a neighboring size, a different diameter or more grooves, send us the data of the original pulley: diameter, section, number of grooves and shaft diameter. With that we look for or manufacture the equivalent part. We can also guide you if the pulley is mounted with a taper bushing or directly on the shaft. The idea is that you don't buy blindly: first we confirm that the part fits and transmits as you need.
