The pulley 130 3C is a V-belt drive pulley, section C, with three grooves and 130 mm diameter. It is used to drive shafts from a motor, distributing power among three belts in parallel to transmit more torque without increasing the diameter. It is an in-house manufactured part, EMMAR Accesorios Industriales brand, designed for equipment that works with continuous loads and needs a balanced pulley with precisely machined grooves.

This item is a pulley with a 130 mm diameter, 3 grooves and section C. Those are the three data points that define the part: the 130 mm outer diameter, the number of grooves (3) and the belt profile it houses, section C. The designation POLEA 130 3C summarizes those three variables. Because it is in-house manufactured, EMMAR brand, it is machined at the factory with dimensional control over the diameter, the pitch between grooves and the profile, so that the three belts work with the same tension.

It is used in belt drives where the load needs to be distributed among several grooves: screw compressors, industrial fans, centrifugal pumps, mills, conveyor belts and continuous process machines. Section C allows absorbing medium and high power at moderate peripheral speeds. Having three grooves, the pulley can transmit approximately three times the power of a single-groove pulley of the same diameter, provided the rest of the system keeps up.

To mount it, check that the shaft and keyway are clean and free of burrs, and that the pulley fits with a fit that does not require blows. Align the driving and driven pulleys with a straightedge or an alignment laser: angular or parallel misalignment wears the grooves and belts unevenly. Tension the belts according to the belt manufacturer's manual and check the tension after the first hours of operation. If the pulley is mounted on a shaft with a bearing, make sure the radial load does not exceed what the bearing allows.

If you need a pulley with another number of grooves, another diameter or a different section, it can be custom manufactured. To order an equivalent, send us the part number POLEA 130 3C or the data you have: diameter, number of grooves, belt section and bore type (cylindrical, tapered or with bushing). With those data we confirm whether a pulley from the same series or a special manufacturing is better.

MR Accesorios Industriales manufactures pulleys, split plummer block housings and ANSI chains, and sells bearings, power transmission, seals, bushings, mounting tools and lubricants.
