The 210 5B pulley is a V-belt drive pulley, section B, with a 210 mm diameter and 5 grooves. It is used to transmit power between parallel shafts in industrial equipment, where a stable transmission ratio and good heat dissipation are required. It is in-house manufacturing, EMMAR brand, designed for replacements and new assemblies in plants, workshops and production lines that work with electric motors and rotating machinery.

This item is a pulley with a 210 mm diameter, 5 grooves and section B. The designation POLEA 210 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 of medium profile, suitable for transmitting moderate to high power at the peripheral speeds usual in industrial equipment. The pulley is machined at MR with dimensional control so that the grooves seat the belt without slipping or premature wear.

Typical applications include centrifugal fans, screw compressors, centrifugal pumps, conveyor belts and machine tools. In all those cases the 210 5B pulley makes it possible to couple an electric motor to the driven machine with a transmission ratio defined by the diameters of the driving and driven pulleys. Having 5 grooves, it accepts several belts in parallel, which distributes the load and provides margin against the failure of one belt, something useful in continuous-operation equipment.

To correctly select this pulley, take into account the pitch diameter, the number of grooves and the belt section. Section B requires grooves with a standardized angle and depth; if the existing pulley has another profile, it does not work as a direct replacement. Also check the shaft diameter and the type of fastening (keyway, taper bushing or set screw) before mounting. Misalignment between pulleys accelerates wear on the belt and on the equipment's bearings.

If you need a nearby size or an equivalent, send us the part number POLEA 210 5B by WhatsApp along with the shaft diameter, the number of grooves and the belt section you are using. With that data we can confirm whether there is an in-house manufactured pulley that fits or whether it is better to machine a special size. We can also advise you on the type of bushing or fastening if you do not have the original equipment's data sheet.

MR Accesorios Industriales manufactures this pulley locally, with more than 80 years of experience in power transmission. If your equipment is out of service or you are assembling a new drive, write to us by WhatsApp with the part number and the shaft data. We will quote the 210 5B pulley or the variant that best suits your application.
