The EMMAR 260 3C is a V-belt drive pulley with a 260 mm diameter, three grooves, and section C. It is built for industrial drives that need a larger diameter to keep speeds moderate while transmitting power through C-section belts. Common installations include compressors, pumps, fans, and other process equipment.

Reading the code is straightforward: 260 is the outside diameter in millimeters, 3 is the number of grooves, and C is the belt section. The complete designation POLEA 260 3C captures those three values. This pulley is manufactured by EMMAR, with dimensional control and balancing so it runs smoothly at normal operating speeds. The three grooves let you run multiple C-section belts on the same shaft, which supports higher power transmission or provides belt redundancy.

This size and groove count suit drives that call for moderate speed ratios and higher torque. You will find it on screw compressors, large centrifugal pumps, industrial fans, mills, mixers, and continuous process lines. It also works on electric motor shafts and machine tool spindles where a larger driving or driven pulley is needed. Because of its diameter, check the space around the pulley and confirm alignment with the mating pulley before installation.

When selecting or replacing this pulley, gather the shaft diameter, keyway type, and fastening method: set screw, taper, or bushing. Make sure the belt section is C and that the groove count matches the mating pulley. Proper alignment between pulleys prevents uneven belt and bearing wear. If the pulley will run at high revolutions, verify balancing. During installation, use the right tools and avoid striking the pulley directly on its edge.

If you need a different groove count, diameter, or belt section, MR can manufacture it or locate an equivalent. To request a replacement, send the code POLEA 260 3C or the original pulley data: diameter, grooves, section, and fastening type. We will quote the option that fits your equipment and can advise on belt section or minimum recommended diameter if you are unsure.
