The 650 5C pulley is an in-house manufactured power transmission pulley, EMMAR brand, with a 650 mm diameter and 5 grooves for section C belts. It is used to drive large shafts in industrial equipment, where torque must be transmitted with several belts in parallel. Its construction allows aligning several grooves on the same shaft and distributing the load among the belts. If you need a pulley to replace an existing one or for new equipment, send us the part number and we will quote you.

This pulley has a 650 mm diameter, 5 grooves and section C. It is a V-belt drive pulley, designed to be mounted on a shaft and receive several belts in parallel. Section C defines the groove profile that corresponds to that type of belt, and the 5 grooves allow adding transmission capacity without increasing the diameter. The part is manufactured at MR and is identified with the part number POLEA 650 5C, which is the one you need to send to order it.

It is used in drives of equipment with large diameter shafts: mills, mixers, high-flow pumps, industrial fans, conveyor belts and continuous process machines. It also appears in gear reducers and transmissions where a speed ratio must be maintained with several belts. In food, chemical or aggregate processing plants, this type of pulley is common for driving equipment that starts under load and needs a robust transmission.

To mount it, verify that the shaft diameter and the key match the pulley bore, and that the belt section is C. The number of grooves must equal the number of belts you are going to use: if you install fewer, the pulley becomes unbalanced in the transmission. Also check the alignment between pulleys and the belt tension, because a pulley of this diameter works with significant moments. If you have doubts, consult us before mounting.

If the part number POLEA 650 5C is not the one you need, we can look at an equivalent. Send us the diameter, number of grooves and section, and we will find the option that best suits your shaft and your belts. We can also review whether a pulley of another diameter or with another number of grooves is better for the same equipment. The more data you give us, the faster the response.

Send the part number POLEA 650 5C by WhatsApp to MR Accesorios Industriales and we will quote you. If you have an old pulley or a sample, send us a photo and the shaft measurements, and we will review it with you. We handle technical inquiries on mounting, selection and equivalences so that you install the correct pulley on your equipment.
