The 170 4B pulley is a V-belt transmission pulley, manufactured by EMMAR Accesorios Industriales. It has a 170 mm diameter, 4 grooves and section B, which makes it suitable for transmitting power in equipment that works with several belts in parallel. It is used in industrial machines, fans, compressors and transmission systems where a robust and balanced pulley is needed. Because it is of in-house manufacturing, MR controls the machining and the quality of the assembly.

This item is a pulley with a 170 mm diameter, 4 grooves and section B. The designation POLEA 170 4B summarizes those three variables: the 170 mm outer diameter, the number of grooves (4) and the belt profile it corresponds to, section B. The grooves are machined so that section B V-belts seat correctly and transmit motion without slippage. It is an in-house manufactured part, EMMAR brand, designed to be mounted on shafts and to form part of a belt transmission system.

The typical applications of a 4-groove section B pulley appear in equipment that requires transmitting torque with several belts: industrial fans, screw compressors, centrifugal pumps, conveyors and machine tools. It is also found in transmission systems where the aim is to distribute the load across four belts to reduce the stress on each one and improve the reliability of the assembly. Because it is a section B pulley, it is used with belts of that profile, which are widely used in industry.

To mount and select this pulley, take into account the shaft diameter, the type of keyway and the fastening system you are going to use. Verify that the pulley is aligned with the driven pulley and that the belt tension is adequate to avoid vibrations and premature wear. The number of grooves (4) and section B define how many belts you can mount and of what type. If you need to replace an existing pulley, the safest approach is to compare the complete designation and the shaft dimensions before ordering it.
