Description
EMMAR POLEA 360 3B 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 360 3B and any equivalents.
The EMMAR 360 3B is a three-groove V-belt pulley with a 360 mm diameter, built to section B. It transfers power between parallel shafts in industrial drives, allowing speed changes and letting multiple belts share the load. Because it is manufactured in-house, the groove profile, balance and bore alignment are controlled during production.
With a 360 mm diameter and three section B grooves, this pulley accepts three belts of that profile running side by side. Section B determines the groove shape and the belt width it takes. Running three belts in parallel spreads the load across them and gives some redundancy if one belt fails. The 360 mm diameter is a common size for medium-speed machinery.
Typical installations include machine tools, compressors, fans, centrifugal pumps, conveyors and process equipment, as well as gearboxes and drive shafts in food, chemical and aggregate plants. When the original drive uses a three-groove pulley, matching the diameter and section keeps the drive ratio and the driven shaft speed unchanged. Changing the diameter alters the speed, so the whole drive train should be reviewed.
Selection depends on pitch diameter, belt section, number of grooves and shaft diameter with its keyway. Before mounting, clean the shaft and bore and remove any burrs. Align the pulleys with a straightedge or laser and tension the belts as the equipment manual specifies. A pulley that is off-center or misaligned causes vibration, heat and uneven groove wear. If the drive uses more than one belt, replace the full set at the same time.
If you need a different number of grooves or a bore for another shaft, the pulley can be custom made. To request an equivalent or a variant, send the part number POLEA 360 3B together with the shaft diameter, keyway width and a photo or sketch of the original pulley. That information defines the machining and allows the quote to be prepared. The pulley can also be combined with section B belts and with bushings or hubs when the installation calls for them.
MR Industrial Accessories manufactures this pulley and supplies it alongside belts, bushings and other power transmission components. If you are unsure about an equivalent, send the part number and the equipment details by WhatsApp. The team will reply with the option that fits your machine.

Frequently asked questions
- What does section B mean for this pulley?
- Section B is a V-belt profile that defines the groove shape and the belt width it accepts. This pulley has three section B grooves, so it takes three belts of that profile.
- Can I get it with a different shaft diameter?
- Yes. The bore and keyway are machined to match the shaft where the pulley mounts. Send the shaft diameter, keyway width and a photo or sketch of the original pulley by WhatsApp and we will quote the variant.
- How do I check if it replaces my current pulley?
- Compare the diameter, number of grooves and belt section. If they match, the replacement is direct. If the diameter differs, the driven shaft speed changes and the drive should be reviewed. If in doubt, send us the data and we will advise you.
