The POLEA 130 4B is a V-belt pulley with a 130 mm diameter, 4 grooves, and section B. It is manufactured by MR and is used to transmit power from a drive shaft to a driven shaft while maintaining the transmission ratio and synchronism. This pulley is a key component in machines that rely on multiple belts to distribute the load.

The designation POLEA 130 4B tells you the three key characteristics: the outer diameter, the number of grooves, and the belt profile. The grooves are machined to accept section B V-belts, which are common in medium-power industrial drives. The pulley mounts on the shaft and is secured with a key or set screw, depending on the equipment design.

You will find this pulley in compressors, pumps, fans, mills, mixers, conveyors, machine tools, and process equipment where motion must be transmitted with several belts. The four grooves distribute the load across four belts, reducing the stress on each belt and improving system reliability. This makes it suitable for applications where a broken belt cannot be allowed to stop production.

When selecting a pulley, consider the pitch diameter, number of grooves, belt section, and keyway type. Check that the pulley fits the shaft diameter and the available space. Proper alignment with the driven pulley is essential to prevent uneven belt wear. Use the correct tools and tighten the set screws or fit the key as required.

If you need a different size, groove count, or section, MR manufactures custom pulleys. To request an equivalent, send the part number POLEA 130 4B or specify the diameter, grooves, and section you need. We can also help you if you are unsure about the designation.
