This industrial pulley of 270 mm diameter, with 3 grooves for section B belts, is a power transmission part manufactured by EMMAR. It is used to build or replace V-belt drives in machines that need to move several shafts at once. As it is in-house manufacturing, you can inquire about machining and finishing variants according to your equipment. The commercial designation is POLEA 270 3B and it is identified by its size, number of grooves and section.

The POLEA 270 3B has 270 mm diameter, 3 grooves and section B. That combination defines how many V-belts of profile B you can mount in parallel and over what diameter they work. Section B corresponds to an industrial-type belt profile, and the three grooves allow distributing the load among three belts. The machining of the grooves and the central bore is done in our own factory, so the part is delivered according to the order. If you need to confirm the shaft diameter or the keyway type, it is defined at the time of quoting.

It is used in belt drives of machines and equipment where motion must be carried from a motor to one or several shafts. It appears in compressors, fans, pumps, mixers, conveyor belts and machine tools. It is also common in factory equipment and in production lines that already have a similar pulley and need to replace it. Having 3 grooves, it serves drives that demand more torque than a single-groove pulley, keeping the same outer diameter. It is a wear part: with use, the grooves wear and it is advisable to replace it.

To choose it well, take into account the outer diameter, the number of grooves and the section of the belt you already use. Verify the shaft diameter and the fastening system: it can come with keyway and set screw, with taper bushing or with pilot bore for machining. Also check the alignment between pulleys, because misalignment accelerates wear of belts and grooves. If the pulley is to work at high revolutions, it is advisable to check the balancing. In all cases, the final selection is made with the data of the machine and the existing belt.

If you don't find the exact size, we can manufacture a pulley to measure or look for an equivalent in the power transmission line. For that, send us the part number POLEA 270 3B or the data of the original pulley: diameter, number of grooves, section and shaft diameter. A photo or a sketch with measurements also works. With that we reply whether there is a factory pulley that matches or whether it is better to machine it. Variants are resolved at the factory.
