Description
EMMAR POLEA 240 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 240 3A and any equivalents.
The EMMAR 240 3A is a V-belt pulley with a 240 mm diameter and three grooves for section A belts. It is manufactured in-house by EMMAR, which allows control over groove machining and balancing for smooth rotation and even belt seating. This pulley is used in drives that require defined transmission ratios, and its standardized dimensions make it suitable for both replacement and new builds.
The part number POLEA 240 3A indicates the main specifications: 240 mm diameter, 3 grooves, and section A. Section A is a classic V-belt profile with a narrow cross-section, intended for medium power and moderate peripheral speeds. With three grooves, up to three section A belts can be mounted in parallel, distributing the load and providing some redundancy if one belt fails.
Typical applications include machine tool drives, compressors, fans, centrifugal pumps, conveyor belts, and process equipment. It is also found in agricultural implements and workshop machinery driven by electric or combustion engines. The pulley is manufactured by EMMAR, so the groove geometry and balance are controlled to reduce vibration and promote even belt wear.
When selecting a pulley, consider the pitch diameter, number of grooves, belt section, and shaft fixing type (keyway or other). Ensure the driving and driven pulleys use the same belt section and that the desired transmission ratio matches available diameters. During installation, align the pulleys with a straightedge or laser, tension the belts per the manufacturer's manual, and check shaft parallelism to avoid premature wear.
For an equivalent pulley, send the part number POLEA 240 3A or the drive data: diameter, grooves, section, and shaft type. Custom manufacturing can be evaluated if volume justifies it. Contact us via WhatsApp or email for a quote and technical guidance to select the right pulley for your equipment.

Frequently asked questions
- What does section A mean?
- Section A is a classic V-belt profile with standardized top and bottom widths. It is used in medium power and moderate speed drives. The 240 3A pulley has three grooves for this belt type, allowing up to three belts in parallel.
- Can I replace a pulley from another brand with this one?
- Yes, if the pitch diameter, number of grooves, belt section, and shaft fixing type match. Send the original pulley data via WhatsApp and we will indicate the compatible size.
- How do I order a pulley with a different number of grooves?
- Contact us via WhatsApp with the diameter, section, and number of grooves you need. Since EMMAR manufactures in-house, we can evaluate production of a pulley with the characteristics your equipment requires, within standardized sizes.
