The 250 5C pulley is a V-belt drive pulley, section C, with 250 mm diameter and 5 grooves. It is used to drive shafts from a motor, reducing or increasing revolutions according to the combined diameters. It is an in-house manufactured part, EMMAR brand, designed for equipment that works with important loads and needs a robust, balanced pulley with well-machined grooves so that the belt seats evenly and lasts.

This item is a pulley of 250 mm diameter, 5 grooves and section C. Section C corresponds to wide-profile V-belts, the ones used when a fair amount of power must be transmitted with few grooves. The five grooves allow the load to be distributed among five belts, so the pulley works with more contact surface and less demand on each belt. It is an in-house manufactured pulley, EMMAR brand, not a third-party product.

It is found in drives of large machines: screw compressors, mills, mixers, conveyor belts, high-flow pumps and plant equipment where the motor is far from the shaft to be driven. Also in the field, in augers and elevators, and in workshops that assemble or repair machines with medium and high power electric motors. Where revolutions must be reduced and torque gained, a pulley of this diameter with five grooves is a direct solution.

To mount it, verify that the shaft and keyway are clean and free of burrs, and that the pulley fits without blows. Align the pulleys well with each other: a misalignment of a few degrees wears the belt and the grooves. Tension is adjusted according to the equipment manual or the belt manufacturer's table. If you do not have the data, aim for the belt not to slip on start-up and not to be excessively tight. Check balancing if the equipment rotates fast.

If you need the same pulley with another diameter, another number of grooves or for section B or D belts, a nearby size or an equivalent can be requested. Send the full part number, belt section, outside diameter and number of grooves. With that data we look for the pulley that best suits your drive. If you have the old pulley at hand, send a photo with a ruler next to it and the shaft diameter.
