The 170 3A pulley is a V-belt transmission pulley with section A, three grooves and a 170 mm diameter. It is used to drive parallel shafts in industrial equipment, where torque must be transmitted with a fixed transmission ratio and good belt grip. As it is in-house manufactured, EMMAR brand, the groove machining and balancing are controlled so that the belt seats evenly and lasts as long as it should.

This item is a pulley with a diameter of 170 mm, 3 grooves and section A. Those are the data that come from the designation: 170 is the measurement in millimeters, 3 the number of grooves and A the corresponding belt section. The pulley is mounted on the shaft and transmits motion through the belts that rest in each groove. Section A defines the groove profile, so the belt must be of that same section so that it fits properly and does not slip or wear on the sides.

Typical applications are equipment with parallel shafts and belt transmission: fans, compressors, centrifugal pumps, conveyor belts and factory machines. It is also used in the field, in mixers, augers and elevators, where the environment is demanding and a robust pulley is advisable. Having three grooves allows the load to be distributed among several belts, which provides more transmission capacity and some redundancy if one belt fails. It is a wear part that should be checked when vibrations or noise appear.

To install it, verify that the shaft diameter and the key match the pulley bore, and that the driving and driven pulleys are aligned. Misalignment, even small, eats the belt flanks and generates vibration. Tension is adjusted according to the equipment manual or usual practice: if it is loose, it slips; if it is too tight, it stresses the shaft bearings. Before starting it up, turn the pulley by hand to confirm that it does not rub and that the belts seat in all grooves.

If you need a different size or an equivalent pulley, the fastest way is to send us the complete part number, the number of grooves and the belt section. With that data we can see if there is a pulley of another size in the same line or if it is better to manufacture it. We can also advise you if the original equipment has a pulley with a different number of grooves and you want to maintain the transmission ratio. The more data you provide, the more accurate the answer.
