The 190 5B pulley is a V-belt transmission pulley, section B, with a 190 mm diameter and 5 grooves. It is used to transmit power between parallel shafts in industrial machines and equipment, where a reliable transmission ratio and good belt grip are needed. As it is of in-house manufacturing, EMMAR brand, it can be adjusted to the mounting requirements and complements the rest of the power transmission line.

This pulley has a 190 mm diameter, 5 grooves and section B. It is designed to be mounted on shafts and receive section B V-belts, which are the ones that best adapt to this geometry. The multiple grooves allow the load to be distributed among several belts, which gives more transmission capacity and some redundancy if one belt fails. It is a solid part, machined so that the grooves have the correct angle and depth, thus avoiding premature belt wear.

It is used in fans, compressors, pumps, mills, conveyor belts and machine tools, among other applications. In general, it appears in equipment where the speed of the driven shaft must be reduced or increased relative to the motor. It is also common in installations where vibrations need to be absorbed or the system protected against overloads, since the belt slips before something breaks. Due to its size, it is suitable for medium and high power within section B.

To choose it correctly, take into account the shaft diameter, the type of keyway and the fastening system. Verify that the driving and driven pulleys are aligned so that the belts run evenly and do not come off. The number of grooves must match the number of belts you are going to use. If space is limited, a smaller diameter pulley with more grooves may be preferable. Always check that the belt section matches that of the pulley.

If you need a different size or an equivalent pulley, send us the part number or the shaft dimensions and the section.
