The 310 5C pulley is a V-belt transmission pulley, section C, with 310 mm diameter and 5 grooves. It is used to drive shafts from a motor, reducing or increasing RPM depending on the combined diameters. It is an in-house manufactured part, EMMAR Accesorios Industriales brand, designed for equipment working with significant loads and needing stable transmission. If you are looking for a pulley to replace an existing one or to build a new transmission, this model covers that size range.

This item is a pulley with 310 mm diameter, 5 grooves and section C. The designation POLEA 310 5C summarizes those three data points: the 310 mm outer diameter, the number of grooves (5) and the belt section it accepts, C. The grooves are machined so that the V-belt seats evenly and transmits without slipping. It is an in-house manufactured pulley, EMMAR brand, not a third-party part, and is produced in our facilities with dimensional control over the main measurements.

Typical applications are belt transmissions in industrial equipment: compressors, fans, pumps, mills, conveyor belts and production machines. Section C is chosen when power must be transmitted with larger-section belts, and the 5 grooves allow the load to be distributed among several belts, which provides more transmission capacity and some tolerance to the failure of one belt. It is also used to replace worn pulleys or to change the transmission ratio in an existing machine.

To select and mount this pulley, take into account the shaft diameter, the type of keyway and the fastening system your equipment needs. Verify that the belt section is C and that the number of grooves matches the number of belts you will use. Alignment between pulleys is key: misalignment accelerates belt and groove wear. Before mounting, check that the shaft has no burrs and that the pulley fits without forcing. If the pulley uses a taper bushing or hub, confirm the bushing model.

If you need a different size or an equivalent pulley, send us the code of the part you are replacing, a photo or a sketch with the shaft and keyway measurements. You can also indicate the diameter, number of grooves and belt section you use. With that data we look for the pulley that best fits within our in-house manufacturing line. If it is not a standard size, we evaluate custom manufacturing according to your requirement.
