When you need to transfer power between two shafts, the EMMAR pulley 260 3A gives you a 260 mm diameter, three grooves, and section A profile. It's a solid choice for medium to high torque drives, letting you set the speed ratio by pairing it with a matching driven pulley. The three-groove design means you can run up to three A-section V-belts side by side, boosting capacity without a larger diameter. It's built for keyed shafts and balanced to keep vibration in check.

The part number POLEA 260 3A tells you most of what you need: 260 mm diameter, three grooves, section A. Section A is the classic V-belt with a 13 mm top width, so any belt meeting that standard will sit correctly in the grooves. With three grooves, you can install three belts in parallel, which increases the torque you can transmit compared to a single-groove pulley. The 260 mm diameter is what determines the drive ratio when you pair it with another pulley. We manufacture this pulley in-house, holding concentricity and balance for continuous operation.

You'll find this pulley in machine tools, air compressors, industrial fans, centrifugal pumps, conveyors, and process equipment where shafts are set apart. It also shows up in drives for mills, mixers, and screens. Because it has three grooves, it's often chosen when you want extra torque capacity or a bit of redundancy without going to a larger diameter. It works with section A belts from any maker that follows the standard.

Mounting is straightforward: check that the shaft diameter and key match, and align the pulley with its counterpart to prevent uneven belt wear. Set belt tension according to the belt manufacturer's recommendation—too much tension puts extra load on the shaft bearings. When you're picking a pulley, think about the power you need to transmit, the RPM of the driving shaft, and the ratio you want. If you need help figuring out the driven pulley size, just ask.

Need a different number of grooves, another diameter, or a different section? We can manufacture it or find an equivalent. For a replacement, send the part number POLEA 260 3A or the original pulley's data: diameter, number of grooves, section, and shaft diameter. We can also quote other series and materials to match your application. Message us on WhatsApp and we'll get back to you with the best option.
