Industrial pulley 180 mm, 4 grooves, section C

EMMAR POLEA 180 4C 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 180 4C and any equivalents.

The 180 4C pulley is a V-belt drive component with a 180 mm diameter, four grooves, and a section C profile. It transfers power between parallel shafts in industrial machinery, allowing speed changes with a high-capacity belt. Manufactured in-house under the EMMAR brand, the groove machining and balancing are controlled. It mounts on a keyed shaft and must be aligned with the drive pulley for even belt running.

The 180 4C designation indicates a 180 mm diameter, four grooves, and section C. This defines how many C-section belts can run side by side and the drive ratio you can achieve with a given drive pulley diameter. The groove is machined to the angle and depth for section C, so the belt contacts the flanks rather than the bottom. The body is cast iron, and the hub includes a keyway for shaft mounting.

Typical applications include screw compressors, mills, mixers, centrifugal pumps, induced draft fans, and conveyors. It is also found in woodworking machines, chippers, and pumping equipment where the motor or engine is located away from the driven shaft. With four grooves, the load is shared among multiple belts, enabling more power transmission without increasing pulley diameter.

During installation, verify that the shaft diameter and keyway match the hub, and that the drive pulley is aligned in the same plane. Adjust belt tension using the motor tensioner or slide rail, not by forcing the pulley. When replacing an existing pulley, note the outside diameter, number of grooves, and section; these data allow finding the equivalent in the MR catalogue.

For a different diameter or additional grooves, send the part number POLEA 180 4C via WhatsApp along with a photo of the old pulley and the shaft measurement. The MR Industrial Accessories team will provide a quote. We can also evaluate machining the hub for special shaft sizes.

MR Industrial Accessories manufactures this pulley in-house with dimensional control of the groove and diameter. This allows replacing a worn pulley without altering the rest of the drive system. If you are unsure about the section or number of grooves, consult us before ordering: a poorly selected pulley wears the belt and reduces equipment performance.
