The 200 mm industrial pulley, 3 grooves, section A is a power transmission component that mounts on shafts to drive V-belts. It is used in machines that need to transmit torque with a stable speed ratio, such as compressors, fans, pumps and conveyors. Because it is in-house manufactured, brand EMMAR, machining and balancing are controlled so the belt seats properly and the assembly runs without vibration.

This item is a pulley with a 200 mm diameter, 3 grooves and section A. The designation POLEA 200 3A summarizes those three variables: the outside diameter, the number of grooves and the belt profile it accepts. Section A corresponds to classic narrow-profile V-belts, and the three grooves allow mounting three belts in parallel on the same pulley to distribute the load. Machining is done in our own factory, with verification of concentricity and of the belt seat.

Typical applications appear in permanent plant equipment: screw compressors, centrifugal fans, centrifugal pumps, conveyor belts and machine tools. In all those cases the pulley is part of a belt drive assembly, where a predictable speed ratio and progressive start-up are sought. Because it has three grooves, it is common to see it in drives where redundancy is needed: if one belt breaks, the other two keep transmitting until the replacement is scheduled.

To select and mount this pulley, take into account the pitch diameter, which is calculated from the outside diameter and the belt profile. Verify that the shaft has the correct tolerance and that the keyway matches the pulley's. The alignment between driving and driven pulleys must be within the machine manufacturer's tolerance; angular or parallel misalignment accelerates wear on the belts and on the equipment's bearings. It is also advisable to check tension according to section A and the number of grooves.

If you need a pulley with a different number of grooves, another diameter or a different section, you can request an equivalent. To do so, send the part number POLEA 200 3A or the drawing with the main dimensions: outside diameter, number of grooves, section, shaft diameter and keyway type. With that data we evaluate a custom part within the in-house manufacturing line. The more complete the information, the faster the response.
