The 160 7B pulley is a section B V-belt drive pulley, with a 160 mm diameter and 7 grooves. It is used to transmit power between parallel shafts in industrial equipment, where a stable transmission ratio and capacity for several belts in parallel are needed. It is in-house manufacturing, EMMAR Accesorios Industriales brand, which allows replacing sizes and grooves according to the equipment's needs. It is mounted on shafts with a keyway and aligned with the driving pulley to avoid uneven belt wear.

This pulley has a 160 mm diameter, 7 grooves and section B. That combination defines how many profile B V-belts can work in parallel and what transmission ratio is achieved according to the diameter of the driving pulley. The number of grooves allows distributing the load among several belts, which reduces the tension on each one and improves drive continuity. The 160 mm diameter conditions the tangential speed: the larger the diameter, the higher the belt speed for the same shaft speed.

It is used in drives for fans, centrifugal pumps, compressors, conveyor belts and machine tools that work with section B belts. It also appears in process equipment where power needs to be transmitted between an electric motor and a reducer or a working shaft. In food, water treatment and mining plants, this type of pulley is chosen when the available space allows several belts and smooth running is sought, with less vibration than gear transmission.

To select it, verify the pitch diameter, the number of grooves and the section of the belt you already have mounted. Check the keyway and the shaft diameter: the pulley must fit with the proper fit and be secured without play. Alignment between driving and driven pulleys is key so that the belts do not come off or wear on one side. If the equipment works with variable loads, it is advisable to calculate the power to be transmitted and the number of belts needed so as not to overload the assembly.

If you need a nearby size or an equivalent pulley, send us the full code, the number of grooves and the belt section. With that data we can verify whether there is an in-house manufactured pulley that fits or whether it is better to modify the diameter. We can also check the keyway and the type of hub so that mounting is direct. The more equipment data you give us, the faster the response.
