Description
EMMAR POLEA 310 4C belongs to pulleys, part of our Power transmission range. Tell us how many you need by WhatsApp or email and we'll get back to you promptly with a quote for POLEA 310 4C and any equivalents.
This EMMAR pulley, part number POLEA 310 4C, is a 310 mm, 4-groove, section C power transmission component. It mounts on a machine shaft to accept V-belts and transfer rotary motion from a motor to another shaft. Speed changes according to the diameters of the opposing pulleys. In equipment running under continuous load, alignment and dimensional balance determine how long the belts and bearings last.
The designation POLEA 310 4C carries the key selection data: 310 mm size, 4 grooves and section C. Section C is a heavy-duty industrial V-belt profile, and the four grooves let four belts run in parallel on the same pulley. When paired with another pulley of the same profile, the 310 mm diameter sets the transmission ratio.
Section C pulleys with four grooves are common in equipment that transmits high power with some redundancy: screw compressors, high-flow industrial fans, mills, mixers, process centrifugal pumps and belt conveyors. The pulley mounts on the driven equipment shaft or the motor shaft, and the belt set spreads the load across the four grooves.
Before mounting, confirm that the 310 mm outside diameter fits the available space and matches the transmission ratio you need. Use only section C belts; do not mix sections on one pulley. Check alignment between pulleys with a straightedge or laser, and tension the belts evenly across all four grooves. The keyway and shaft fit must follow the equipment manufacturer's tolerances.
For an equivalent pulley, send the part number POLEA 310 4C or the full designation by WhatsApp or email. You can also provide the number of grooves, section and diameter your machine requires, and we will confirm whether it fits our manufacturing line. Our own profiles and machining allow sizes to be adapted within section C.
MR Industrial Accessories LLC manufactures this pulley and supplies it alongside belts, bearings, housings and mounting tools. If your equipment needs a 310 mm pulley with 4 grooves, section C, contact us with the part number for a quote. We also help you match pulleys and belts so the drive runs aligned and correctly tensioned.

Frequently asked questions
- What does section C mean on this pulley?
- Section C is a standardized industrial V-belt profile that defines the groove width and height where the belt seats. This pulley has four 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. A belt of a section other than C causes premature wear, loss of transmission and risk of the belt coming off. Always match the belt to the pulley section.
- How do I request a pulley with a different number of grooves or diameter?
- Send us the diameter, number of grooves and section you need by WhatsApp or email. Because 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.
