For drives that rely on V-belts, the EMMAR 360 3A pulley offers a 360 mm diameter, three grooves, and a section A profile. It is built to transfer torque to a shaft at a set ratio. Since EMMAR produces this pulley in its own facility, the groove cutting and balancing are controlled to support concentric running and proper alignment when installed.
The 360 3A carries a 360 mm diameter, three grooves, and section A. Section A is a traditional narrow V-belt profile, and having three grooves lets the load be shared across three belts, giving more transmission capacity than a single-groove version. When paired with the driven pulley, the 360 mm diameter sets the transmission ratio. EMMAR machines the groove to dimensional tolerances and checks concentricity so the belts sit uniformly.
Typical uses include belt drives on fans, compressors, centrifugal pumps, mills, mixers, conveyors, and test stands. It also suits situations where motor speed needs to be stepped up or down using a large-diameter, multi-groove pulley. This size is often chosen when an existing section A drive must be replaced while keeping the same diameter and groove count.
When selecting, confirm the pitch diameter, number of grooves, and belt section. Verify that the bore and keyway fit the shaft, and that balancing matches the operating speed. During installation, align the pulleys with a straightedge or laser to avoid uneven belt wear and vibration. Set belt tension per the equipment manual; too little causes slipping, too much loads the shaft bearings.
Need a different groove count, diameter, or section? Ask for an equivalent. Send the part number MR-POLEA-A3-360 or the designation POLEA 360 3A by WhatsApp, along with your shaft diameter, keyway, and belt section. MR Industrial Accessories will reply with a quote. If you are unsure about matching a pulley that is no longer available, send a photo or drawing of the shaft and we will help you determine the size. Service is handled via WhatsApp with technical support.

Frequently asked questions
- What does section A mean?
- Section A is a classic V-belt profile. The pulley's groove is machined for that profile, so only section A belts should be used. Other belt sections will not fit without altering the groove.
- Can I order a different bore diameter?
- Yes. The pulley is made with the bore and keyway to match your shaft. Send the shaft diameter, keyway length, and required number of grooves by WhatsApp, and we will quote the manufacturing.
- How can I tell if this pulley replaces mine?
- Compare the pitch diameter, number of grooves, and belt section. If they match, it is equivalent. If you are unsure, send a photo of the old pulley with a ruler next to it and we will confirm.
