The POLEA 500 1B is a single-groove V-belt pulley with a 500 mm diameter, designed for section B belts. Manufactured by EMMAR, it suits drives that need a simple speed ratio, such as fans, pumps, compressors, and conveyors. The part number combines the outside diameter, groove count, and belt profile, making selection straightforward for maintenance and purchasing teams.

This pulley is identified by three key variables: a 500 mm outside diameter, one groove, and a section B profile. Section B V-belts are common in medium-power industrial drives. The groove is machined so the belt seats evenly across the arc, promoting consistent contact. The pulley is supplied without a belt or bushing unless ordered as an assembly.

Typical uses for a 500 mm single-groove section B pulley include centrifugal fans, water pumps, screw compressors, conveyor belts, and general factory machinery. It also works as a driven pulley in single-ratio reducers, where the goal is to lower motor RPM without a gear reducer. Always confirm that the transmitted power and operating RPM fall within the acceptable range for a section B belt.

When mounting, first verify the shaft diameter and fastening method: key, taper bushing, or set screw, depending on the equipment. Next, check alignment between driving and driven pulleys, since misalignment accelerates belt and groove wear. Adjust belt tension according to the equipment manual or standard practice for section B. For replacement, note the diameter, number of grooves, and section as minimum data.

If you need an equivalent pulley, send the part number POLEA 500 1B or the original pulley data: diameter, grooves, section, and shaft diameter. We can propose an in-house manufactured variant that fits. We can also assess whether moving to two or more grooves is advisable for the same power. Quotes are handled via WhatsApp or email, and we reply with the corresponding reference.
