Description
EMMAR POLEA 240 4A 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 4A and any equivalents.
The 240 4A pulley from EMMAR is a V-belt drive component built for power transmission between parallel shafts. It measures 240 mm in diameter and has four grooves sized for section A belts. Because it is manufactured in-house, it can be adapted to specific assembly requirements.
In the 240 4A designation, the numbers and letter tell you the essentials: 240 mm outside diameter, four belt grooves, and section A belts. The pulley mounts on a keyed shaft and is secured with either a set screw or a taper bushing, depending on the setup. Groove machining follows standard tolerances for section A, so each belt seats evenly along the full groove length.
Typical applications include machine tools, pumps, fans, compressors, and conveyors, as well as plant equipment that needs a fixed speed change. With four grooves, you can run one, two, three, or all four belts, which lets you adjust the transmitted power without swapping the pulley. This makes it a practical choice for production lines that require some torque reserve.
When selecting a pulley, check the pitch diameter, belt section, and number of grooves. Confirm that the shaft diameter and keyway match, and that the pulley aligns with the driving pulley to prevent uneven belt wear. Set tension according to the equipment manual or the belt maker's guidance. If space is tight, consider whether a smaller diameter or fewer grooves would work better.
Need a different size? We can manufacture a pulley with another diameter, groove count, or belt section. To request an equivalent, send the original part number, the section and number of grooves, and the shaft dimensions. We will quote the best match. If you don't have the data sheet, we can help you identify the right pulley.

Frequently asked questions
- What does 240 4A mean on this pulley?
- 240 is the diameter in millimeters, 4 is the number of grooves, and A is the belt section. This is the standard way to name V-belt pulleys. With that data, we can quote an equivalent.
- Can I use fewer belts than grooves?
- Yes, you can mount one, two, three, or all four belts. Using fewer belts reduces the transmitted power. Empty grooves do not affect operation, but the driving pulley should have the same number of available grooves.
- How do I request a pulley with a different size?
- Write to us via WhatsApp or email with the diameter, number of grooves, and section you need, plus the shaft data. If you have the original pulley part number, include it. We will quote the custom manufacturing.
