The 550 2C pulley is a V-belt drive pulley, section C, with 550 mm diameter and two grooves. It is used to drive shafts from a motor, reduce or increase speed and transmit torque in industrial equipment. It is in-house manufacturing, EMMAR brand, which allows replacing sizes and grooves according to each machine's needs. If you have to replace a worn pulley or assemble a new drive, this model is quoted via WhatsApp with the exact code.

This pulley has 550 mm diameter, 2 grooves and works with section C belts. It is a cast iron pulley, machined so that the grooves seat the belt without premature wear. Section C accepts higher-profile belts than sections A or B, so it is chosen when more power must be transmitted with fewer grooves. The 550 mm diameter defines the transmission ratio: the larger it is relative to the motor pulley, the lower the final speed of the driven shaft.

It is used in machine drives with significant loads: screw compressors, mills, mixers, screens, centrifugal fans, high-flow pumps and plant equipment. It also appears in transmission lines where a flywheel is needed in addition to the speed ratio. In all those cases, the pulley is mounted on the shaft with key and axial fixing, and alignment with the drive pulley is what defines whether the belt lasts or breaks prematurely.

To select this pulley properly, first verify the pitch diameter required by your drive and the number of grooves according to power and service factor. Then check the shaft diameter and the type of bushing or bore: the pulley is machined for the shaft you will use. During assembly, align the grooves with the drive pulley using a straightedge or laser, tension the belt according to the manufacturer's manual and check shaft parallelism. A misaligned pulley wears the belt in a few weeks.

If you cannot find the exact size, you can request a pulley with another diameter or with more grooves within the same section C, or evaluate replacement with a pulley of another section if space allows. For that, it is advisable to send the current diameter, number of grooves, belt section and a photo of the assembly. With that data, it is determined whether it is better to manufacture a custom pulley or adapt the drive to a standard size.
