The 500 3A pulley is a V-belt drive pulley, manufactured by EMMAR Accesorios Industriales. It has a 500 mm diameter, 3 grooves and section A. It is used to transmit power from a motor to a driven shaft, keeping the transmission ratio and peripheral speed within design values. It is a key component in machines that run under continuous loads and require good alignment and correct belt tension.

This pulley has a 500 mm diameter, 3 grooves and section A. The designation 500 3A indicates exactly those three things: the outside diameter, the number of grooves and the belt profile it accepts. The grooves are machined so that the belt seats evenly and does not come off. The 500 mm diameter places it in the range of large pulleys, typical of transmission ratios where the driven shaft turns slower than the motor.

It is used in power transmission equipment: industrial fans, centrifugal pumps, compressors, conveyor belts and machine tools. Also in installations where motor speed needs to be reduced and torque increased on the output shaft. Due to its size, it should be mounted on robust shafts with supports that absorb radial loads. It is commonly found in process plants, workshops and agro-industrial facilities.

To mount it, check that the shaft and keyway are clean and free of burrs. The pulley is secured with a key and set screw or with a taper locking system, depending on the case. It is essential to align the drive and driven pulleys with a straightedge or laser; misalignment accelerates belt and bearing wear. Belt tension is adjusted according to the belt manufacturer's manual, neither too loose nor too tight.

If you need a pulley with a different number of grooves, another diameter or for another belt section, we can manufacture it. MR Accesorios Industriales has more than 80 years in the industry and manufactures split plummer block housings, ANSI chains and pulleys. To request a nearby size or an equivalent, send us the part number, diameter, number of grooves and belt section you use. With that data we will quote the pulley that best suits your machine.
