Description
EMMAR POLEA 130 3C 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 130 3C and any equivalents.
The POLEA 130 3C is an EMMAR-brand V-belt pulley with a 130 mm diameter, three grooves, and a section C profile. It is manufactured in-house and is used to transmit power from a motor to a driven shaft through three parallel belts, which allows higher torque capacity without increasing the pulley diameter. The part is designed for equipment that operates under continuous loads and requires a balanced pulley with accurately machined grooves.
The designation POLEA 130 3C identifies the three key variables of the part: the 130 mm outer diameter, the number of grooves (3), and the belt section it accepts (C). Because it is manufactured in-house under the EMMAR brand, the diameter, groove pitch, and profile are machined under dimensional control so that all three belts run at the same tension.
This pulley is used in belt drives where the load is distributed across multiple grooves, such as screw compressors, industrial fans, centrifugal pumps, mills, conveyor belts, and continuous process machines. Section C is suitable for 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.
When mounting, ensure the shaft and keyway are clean and free of burrs, and that the pulley fits without requiring blows. Align the driving and driven pulleys with a straightedge or alignment laser; angular or parallel misalignment causes uneven wear on grooves and belts. Tension the belts according to the belt manufacturer's manual and recheck 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 the bearing's allowable limit.
If you need a different number of grooves, another diameter, or a different section, the pulley can be custom manufactured. To order an equivalent, send 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 that information, we confirm whether a pulley from the same series or a special manufacturing is better.
MR Industrial Accessories manufactures pulleys, split plummer block housings, and ANSI chains, and supplies bearings, power transmission components, seals, bushings, mounting tools, and lubricants. If you are unsure which pulley matches your equipment, contact us on WhatsApp with the part number POLEA 130 3C and we will help you identify the right part.

Frequently asked questions
- What does POLEA 130 3C mean?
- It indicates a pulley with a 130 mm diameter, 3 grooves, and a section C profile. The number is the outer diameter, the 3 is the number of grooves, and the C is the V-belt section. These three data points identify the part.
- Can it be manufactured with a different number of grooves?
- Yes. Because it is manufactured in-house under the EMMAR brand, it can be machined with 1, 2, 3, or more grooves, and with the diameter you require. Send us your drive specifications and we will quote a custom pulley.
- How do I order an equivalent pulley?
- Contact us on WhatsApp with the part number POLEA 130 3C or with the data you have: diameter, grooves, section, and bore type. We will indicate a pulley from the same series or arrange manufacturing.
