The 130 3C pulley is a V-belt drive pulley, section C, with three grooves and a 130 mm diameter. It is used to drive shafts from a motor, distributing power across 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 runs under 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 outside diameter, the number of grooves (3) and the belt profile it accommodates, 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 groove pitch and the profile, so that all three belts work at the same tension.

It is used in belt drives where the load must be spread across several grooves: screw compressors, industrial fans, centrifugal pumps, mills, conveyor belts and continuous process machines. Section C can handle medium and high power at moderate peripheral speeds. With 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 supports it.

To mount it, check that the shaft and keyway are clean and free of burrs, and that the pulley fits without requiring hammering. Align the driving and driven pulleys with a straightedge or a laser alignment tool: 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 a different number of grooves, a different diameter or a different section, it can be custom manufactured. To request an equivalent or a nearby size, 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 a bushing). With that data we will confirm whether a pulley from the same series or a special manufacturing is the right choice.

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