The 500 5B pulley is a V-belt drive pulley, section B, with 500 mm diameter and 5 grooves. It is used to drive machine shafts from a motor, transmitting torque through belts and regulating speed according to the diameter ratio between pulleys. It is an in-house manufactured part, EMMAR Accesorios Industriales brand, designed for industrial applications requiring robustness and precise alignment.

This item is a pulley with 500 mm diameter, 5 grooves and section B. The designation POLEA 500 5B summarizes those three variables: the outside diameter, the number of grooves and the belt profile it accepts. Section B corresponds to classic V-belts with B profile, and the 5 grooves allow mounting up to five belts in parallel on the same disc. It is an in-house manufactured pulley, EMMAR brand, not a third-party product.

It is used in belt drives of industrial machines: compressors, fans, pumps, mills, mixers and transmission equipment in general. When the drive shaft rotates at a fixed speed, the diameter of this pulley defines the driven shaft speed together with the pulley at the other end. The 5 grooves allow distributing the load among several belts, which is useful in drives with sustained torque demand.

To select it, take into account the diameter of the driving pulley, the center distance and the power to be transmitted. The number of grooves must match the number of belts you are going to mount, and section B must be the same on both pulleys. Check the shaft diameter and the keyway type before mounting, and check the alignment between pulleys to avoid uneven belt wear.

If you need a pulley with a different diameter, a different number of grooves or a different section, it can be custom manufactured. We can also evaluate a replacement if you send us the dimensions of the current pulley: diameter, number of grooves, section and shaft diameter. With that data, at MR Accesorios Industriales we guide you toward the closest option within our in-house manufacturing line.

To request a quote for this pulley or ask about a nearby size, send us the part number POLEA 500 5B by WhatsApp. If you have doubts about the equivalence with the pulley you are replacing, attach a photo or the shaft and groove measurements. That way we can quickly confirm whether this pulley fits your application or whether it is better to manufacture a specific variant.
