EMMAR POLEA 310 4C is a reference of pulleys, within Power transmission. Request a quote for POLEA 310 4C via WhatsApp or email with the quantity you need; we respond promptly with the quote and equivalents.
The 310 mm, 4-groove, section C industrial pulley 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, increasing or reducing speed according to the opposing diameters. It is a key part in equipment working under continuous load, where alignment and dimensional balance define the service life of the 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-duty industrial V-belt profile, and the 4 grooves allow four belts to be mounted 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 a certain redundancy: screw compressors, high-flow industrial fans, mills, mixers, process centrifugal pumps and belt conveyors. In these systems, the pulley is mounted on the shaft of the driven equipment or the motor, 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 with the desired transmission ratio. Section C requires belts of the same profile; do not mix different sections on the same pulley. Check alignment between pulleys with a straightedge or laser, and tension the belts evenly across the four grooves. The keyway and the fit on the shaft must follow the equipment manufacturer's tolerances.
If you need an equivalent pulley, send us the part number POLEA 310 4C or the full designation by WhatsApp. You can also tell us the number of grooves, the section and the diameter your machine requires, and we will confirm whether it is within our manufacturing line. We work with our own profiles and machining, which allows sizes to be adapted within section C.
MR Accesorios Industriales manufactures this pulley at its plant and sells it together with belts, bearings, housings and mounting tools. If your equipment requires a 310 mm pulley with 4 grooves, section C, write to us on WhatsApp with the part number and we will send you the quote. We also advise on the combination of pulleys and belts so that the drive runs aligned and with the correct tension.

Frequently Asked Questions
- What does it mean that the pulley is section C?
- Section C is a standardized industrial V-belt profile. It defines the width and height of the groove where the belt seats. This pulley has 4 section C grooves, so it accepts four belts of that profile working in parallel.
- Can I use belts of another section on this pulley?
- No. Each section has a specific groove angle and depth. Using a belt of a section other than C causes premature wear, loss of transmission and risk of the belt coming off. Always verify that the belt matches the pulley section.
- How do I request a pulley with a different number of grooves or diameter?
- Write to us on WhatsApp indicating the diameter, the number of grooves and the section you need. Since it is in-house manufacturing, EMMAR brand, we evaluate the feasibility of machining the requested size within section C and confirm with you through the same channel.
