The 340 8C is a section C V-belt pulley with a 340 mm diameter and 8 grooves, produced under the EMMAR brand. It transfers power between parallel shafts in industrial drives, and the speed ratio depends on the diameters of the paired pulleys. Because it is made in-house, the machining and balancing are controlled for smooth running. This pulley is a common maintenance item on production lines, mills, compressors and ventilation systems.

With a 340 mm diameter, 8 grooves and a section C profile, this pulley is designed for wide-profile V-belts that handle high power. The eight grooves spread the load across multiple belts, lowering the stress on each belt and making the drive more reliable. When matched with another pulley, the 340 mm diameter sets the transmission ratio. The part is cast iron or machined steel depending on the application, and it is manufactured at MR with dimensional checks.

Typical uses include machines that move power from a motor to a driven shaft: mills, mixers, screw compressors, centrifugal fans, conveyor belts and pumping equipment. You will also find it in food, chemical and aggregate processing. An 8-groove pulley is often chosen where redundancy or high torque capacity is required. Mounting can be on a keyed shaft or with a taper bushing, depending on the equipment design.

To select the right pulley, confirm the pitch diameter, groove count, belt section and the bushing or bore type. Make sure the motor or machine shaft matches in diameter and keyway length. Alignment between pulleys is critical: misalignment speeds up belt wear and causes vibration. Also inspect belt tension and groove condition before installation. If the load varies, consider balancing.

If you need a different groove count, diameter or section, we can manufacture it or locate an equivalent. Send the original pulley part number, the full designation (for example, 340 8C) and your shaft dimensions: diameter, length and keyway. A photo of the part and the equipment nameplate also helps. With that information we check compatibility and propose the best alternative for your machine.

To request a quote for this 340 8C pulley, send the part number by WhatsApp or email to MR. We reply with manufacturing and bore machining options. If you are unsure about the section or number of grooves, attach a photo of the belt and the old pulley. That way we can advise you directly and help you avoid a part that does not fit.
