The 160 7B pulley is a V-belt drive pulley with section B, 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 required. It is in-house manufactured, EMMAR Accesorios Industriales brand, which allows replacing sizes and grooves according to the equipment's needs. It is mounted on shafts with 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 section 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 a smooth operation is sought, with less vibration than gear transmission.
To select it, check the pitch diameter, the number of grooves and the section of the belt you already have installed. Check the keyway and the shaft diameter: the pulley must fit with a proper fit and be secured without play. The 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 an equivalent pulley, send us the complete part number, the number of grooves and the belt section. With that data we will propose the in-house manufactured pulley that fits or modify the diameter. We can also check the keyway and the hub type so that the assembly is direct. The more equipment data you give us, the faster the response.

Frequently Asked Questions
- What does it mean that it is section B?
- Section B corresponds to a V-belt profile with standardized width and height measurements. The pulley has grooves with that geometry so that the belt rests on the flanks and transmits by friction. It is not compatible with belts of another section.
- Can I change a 6-groove pulley for this 7-groove one?
- Yes, as long as the diameter and keyway match. With 7 grooves you can use 6 belts or add one more if the power calculation allows it. Check that the total width of the pulley fits in the available space.
- How do I order a pulley with a different size?
- Write to us via WhatsApp with the diameter, the number of grooves and the section you need. As it is in-house manufacturing, we evaluate the feasibility of the size and send you the quote.
