The MR industrial pulley, 340 mm with 7 grooves for section B belts, is a power transmission component manufactured by EMMAR Accesorios Industriales. It is used to drive parallel shafts through V-belts, making it possible to distribute power from a motor to one or several machines. Its robust construction makes it suitable for continuous service in industrial plants, workshops and production lines where reliability and low maintenance are required.
This item is a pulley with a 340 mm diameter, 7 grooves and section B, according to its designation POLEA 340 7B. The 340 mm measurement corresponds to the outside diameter of the pulley, and the 7 grooves can hold the same number of section B V-belts. Section B defines the groove profile, compatible with belts of that type. It is an in-house manufactured part, EMMAR brand, designed to transmit power in pulley and belt systems.
Typical applications include machine tools, compressors, centrifugal pumps, industrial fans, conveyor belts and process equipment. In all cases, the pulley is mounted on a shaft and linked to another pulley by section B belts. The 7 grooves make it possible to distribute the load among several belts, which is useful when greater power needs to be transmitted or when a certain redundancy is sought in case one belt breaks.
To select this pulley correctly, take into account the shaft diameter, the type of keyway and the fastening system (it may be with a taper bushing, set screw or key). Verify that the belt section matches the groove and that the number of grooves is adequate for the power to be transmitted. Mounting must ensure alignment between pulleys to avoid premature wear of belts and bearings. If you need help, contact us.
If you need a pulley with another size, number of grooves or section, we can manufacture it. We can also evaluate an equivalent if you have the part number from another brand. For that, send us the complete data: diameter, number of grooves, section and type of fastening. With that information, we will quote the pulley that best suits your needs.

Frequently Asked Questions
- What does it mean that it is section B?
- Section B refers to the groove profile of the pulley, designed for type B V-belts. This ensures that the belt fits correctly and transmits power without slipping. It is important to respect this designation when replacing the pulley or the belts.
- Can I use this pulley with a different number of belts?
- Yes, the pulley has 7 grooves, but you can use fewer belts if your application allows it. However, to transmit the power for which it was designed, it is recommended to use the appropriate number of belts. If you need a different number of grooves, we can manufacture it to order.
- How do I request a pulley with different measurements?
- Write to us on WhatsApp and tell us what you need: diameter, number of grooves, section and type of fastening. With that data, we will quote a custom pulley. We can also evaluate an equivalent if you send us the part number of the original part.
