The 310 mm industrial pulley, 4-groove section C is a power transmission component mounted on a machine shaft to receive V-belts. Its function is to transmit rotary motion from a motor to another shaft, multiplying or reducing speed according to the facing diameters. It is a key part in equipment working under continuous effort, where alignment and dimensional balance define the service life of belts and bearings.

This item is an in-house manufactured pulley, EMMAR brand, identified with the part number POLEA 310 4C. Its published attributes are: 310 mm size, 4 grooves and section C. Section C corresponds to a heavy industrial type V-belt profile, and the 4 grooves allow mounting four belts in parallel on the same pulley. The 310 mm diameter defines the transmission ratio when combined with another pulley of the same profile.

Typical applications of a section C pulley with four grooves appear in equipment that needs to transmit high power with some redundancy: screw compressors, high-flow industrial fans, mills, mixers, process centrifugal pumps and belt conveyors. In these systems, the pulley is mounted on the driven equipment or motor shaft, and the belt set distributes the load across the four grooves.

To select and mount this pulley, verify that the 310 mm outside diameter is compatible with the available space and the desired transmission ratio. Section C requires belts of the same profile; do not mix different sections on the same pulley. Check the alignment between pulleys with a ruler or laser, and tension the belts uniformly in the four grooves. The keyway and shaft fit must follow the equipment manufacturer's tolerances.

If you need an equivalent pulley or a nearby size, send us the part number POLEA 310 4C or the full designation by WhatsApp. You can also indicate the number of grooves, the section and the diameter your machine requires, and we confirm if it is within our manufacturing line. We work with our own profiles and machining, which allows adapting sizes within section C.

MR Accesorios Industriales manufactures this pulley in its plant and sells it together with belts, bearings, housings and mounting tools. If your equipment requires a 310 mm pulley with 4-groove section C, write to us by WhatsApp with the part number and we send you the quote. We also advise on the combination of pulleys and belts so that the drive works aligned and with the correct tension.
