This EMMAR-manufactured pulley has a 200 mm outside diameter, three grooves, and is designed for section A V-belts. It mounts on a shaft to transmit torque in belt-driven equipment such as compressors, fans, pumps, and conveyors. Because it is produced in-house, the machining and balance are controlled so the belt seats correctly and the assembly runs smoothly.

The part number POLEA 200 3A tells you the key specifications: 200 mm outside diameter, 3 grooves, and section A profile. Section A refers to classic narrow V-belts. With three grooves, you can run three belts in parallel on the same pulley to share the load. Each pulley is machined in our own facility, with concentricity and belt seat checked.

You will find this pulley in continuous-duty plant equipment: screw compressors, centrifugal fans, centrifugal pumps, conveyor drives, and machine tools. In these setups, the pulley is part of a belt drive where a consistent speed ratio and gradual startup are important. The three-groove design is also useful when redundancy is needed: if one belt fails, the remaining two can keep the drive running until a replacement is scheduled.

When selecting and mounting this pulley, consider the pitch diameter, which is derived from the outside diameter and the belt profile. Make sure the shaft tolerance is correct and the keyway matches the pulley. Alignment between the driving and driven pulleys must be within the machine manufacturer's tolerance; angular or parallel misalignment increases wear on belts and bearings. Also check belt tension according to section A and the number of grooves.

If you need a different number of grooves, another diameter, or a different section, you can request an equivalent. Send the part number POLEA 200 3A or a drawing with the main dimensions: outside diameter, number of grooves, section, shaft diameter, and keyway type. With that information, we can evaluate a custom part within our in-house manufacturing line. The more details you provide, the faster we can respond.
