Description
EMMAR POLEA 550 3A 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 550 3A and any equivalents.
The 550 3A pulley is a V-belt drive component manufactured by EMMAR. It has a 550 mm diameter, 3 grooves, and is designed for section A belts. This pulley transmits power between parallel shafts in industrial machinery, and because it is produced in-house, machining details can be adapted to your specific requirements. It is commonly used in the maintenance of production lines, mills, pumps, and fans.
The designation POLEA 550 3A indicates the key dimensions: 550 mm diameter, 3 grooves, and section A profile. Section A refers to a classic narrow V-belt profile widely used in industrial drives. As an in-house manufactured EMMAR product, the groove machining and balancing are controlled to ensure smooth, vibration-free operation.
This pulley suits equipment that requires torque transmission through multiple belts in parallel, such as industrial fans, centrifugal pumps, compressors, mills, mixers, and conveyors. The three grooves distribute the load across three belts, reducing stress on each belt and improving assembly reliability. It also serves as a replacement in machines already set up for a 3-belt section A configuration.
When selecting or mounting this pulley, consider shaft diameter, keyway type, and fastening method (set screw, taper, or plate). Ensure the driving and driven pulleys are aligned and that the center distance allows proper belt tensioning. The number of grooves must match the number of belts used. If you need to change the transmission ratio, the appropriate diameter and groove count can be evaluated together.
For an equivalent, send the part number POLEA 550 3A or the designation on your equipment. The pulley can be manufactured with a different diameter, groove count, or adapted to a different shaft. Complete assemblies with matching section A belts can also be quoted. Provide shaft data, power to be transmitted, and working rpm for assistance.

Frequently asked questions
- What does section A mean for this pulley?
- Section A is a classic V-belt profile. The pulley grooves are machined to match the angle and dimensions of this belt. It is not compatible with other profiles such as B, C, or 5V without changing the pulley.
- Can I order it with a different diameter or number of grooves?
- Yes, because it is in-house manufactured under the EMMAR brand, the pulley can be machined with the diameter, number of grooves, or bore you need. Send your shaft measurements and desired configuration via WhatsApp or email for a quote.
- How do I know if this pulley replaces the one I have?
- Compare the outer diameter, number of grooves, and belt section. Also check the bore diameter and keyway. If unsure, send a photo or the part number of the original pulley, and we will help you verify it.
