The 220 5B pulley is a V-belt drive pulley manufactured by EMMAR Accesorios Industriales. It has a 220 mm diameter and 5 grooves for section B belts. It is used to transmit power between parallel shafts in industrial equipment, with the advantage that, since it is in-house manufactured, we can adjust the part to whatever you need. If you are assembling or upgrading a drive, this pulley lets you run several grooves simultaneously and maintain alignment.

This pulley has a 220 mm outer diameter and 5 machined grooves for section B belts. Section B is one of the most widely used in medium-duty drives: it accepts classic-profile belts and is available at any power transmission supplier. The 5 grooves allow the load to be distributed among several belts, which provides more torque capacity and a certain redundancy if one belt fails. The grooves are machined with the tolerances required so that the belt seats properly and does not slip.

It is used in machines that need to transmit power from a motor to a working shaft: compressors, fans, pumps, conveyor belts, mixers, small mills and factory equipment. It is also common in the field, in harvesting machines or in implements that use belt drives. Being a 5-groove pulley, it is typical of drives where more than one groove is required so as not to overload the belt.

To mount it, verify that the shaft has the correct diameter and key, and that the pulley bore matches. The pulley is secured with a key and set screw or with a taper bushing, depending on the case. It is important to align the driving and driven pulleys so that the belts run evenly; misalignment accelerates belt and bearing wear. Also check the tension: too little causes slipping, too much stresses the supports.

If you need a different size, we can manufacture it. Provide the diameter, the number of grooves and the section, or directly the part number of the pulley you want to replace. We can also machine the bore with the diameter and key you need. Since it is in-house manufacturing, we have control over the machining and can adjust the part to your machine.
