The 250 5C pulley is a V-belt drive pulley, section C, 250 mm in diameter with 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 significant loads and needs a robust, balanced pulley with well-machined grooves so the belt seats evenly and lasts.

This item is a pulley 250 mm in diameter, 5 grooves and section C. Section C corresponds to wide-profile V-belts, the ones used when a fair amount of power has to be transmitted with few grooves. The five grooves make it possible to share the load 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. Wherever revolutions must be reduced and torque gained, a pulley of this diameter with five grooves is a direct solution.

To mount it, check that the shaft and the keyway are clean and free of burrs, and that the pulley goes on without blows. Align the pulleys with each other well: 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 don't have that data, aim for the belt not to slip on startup and not to be excessively tight. Check balancing if the equipment runs fast.

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