The POLEA 140 2C pulley is a V-belt drive pulley, section C, with a 140 mm diameter and two grooves. It is used to transmit power between parallel shafts in machines and industrial installations, where a reliable transmission ratio that is easy to maintain is required. It is an in-house manufactured part, EMMAR Accesorios Industriales brand, designed to replace worn pulleys or to build a new drive with section C belts.

The POLEA 140 2C is identified by its designation: 140 mm diameter, 2 grooves and section C. It is a cast iron or steel pulley, machined to seat section C V-belts, which have the highest transmission capacity among classic belts. The two grooves allow mounting two belts in parallel, which increases the transmitted power and provides redundancy if one belt breaks. The 140 mm diameter determines the peripheral speed and the transmission ratio according to the diameter of the driven pulley.

It is used in fans, compressors, centrifugal pumps, mills, mixers, conveyors and machine tools. It also appears in irrigation equipment, treatment plants and suction systems. It is common in installations where speed needs to be reduced or increased between an electric motor and the working shaft, with simple maintenance and accessible spare parts. Due to its size, it suits medium power ratings within section C.

To select it, take into account the diameter of the driving and driven pulleys, the motor power, the rpm and the type of load. Verify that the belt is section C and that the number of grooves matches the number of belts you are going to mount. Check the condition of the keyway and the shaft before mounting. Alignment between pulleys must be careful to avoid irregular belt wear and vibration. If the pulley runs at high revolutions, balancing should be checked.

If you need a different size or an equivalent pulley, send us the part number POLEA 140 2C or the shaft dimensions, the grooves and the section. We can also manufacture custom pulleys from a sample or drawing. For that, send us the outer diameter, the bore diameter, the width, the number of grooves and the belt type. With that data we will quote the part that best suits your machine.
