The 170 2B pulley is a power transmission component manufactured by MR Accesorios Industriales. It is used to transmit motion between shafts using V-belts of section B. With a 170 mm diameter and two grooves, it allows building simple, robust transmissions that are easy to align. It is a key part in machines that need to maintain a constant speed ratio and absorb moderate loads.
This pulley has a 170 mm outer diameter, two grooves and section B. It is designed to be mounted on shafts and to receive V-belts with a B profile. Its two-groove design doubles the transmission capacity compared to a single-groove pulley, while keeping a compact width. In-house manufacturing, EMMAR brand, guarantees the dimensional control of each part.
It is used in a wide variety of industrial applications: fans, centrifugal pumps, compressors, conveyors, mixers and machine tools. It is also common in refrigeration equipment and in transmission systems where a speed reduction or increase with low maintenance is required. Due to its size, it is suitable for medium power and moderate peripheral speeds.
To correctly select this pulley, take into account the shaft diameter, the type of keyway and the fastening system. Verify that the belt is section B and that the number of grooves matches the number of belts. It is important to align the pulleys and tension the belts according to the belt manufacturer's recommendations. If you need help, contact us.
