The 220 7B pulley is a power transmission pulley of in-house manufacturing, EMMAR Accesorios Industriales brand. It is designed to build V-belt drives of section B, with seven grooves that allow the load to be distributed among several belts and thus transmit more power without increasing the diameter. It is used in equipment where a stable transmission ratio and good belt grip are needed, such as fans, compressors, pumps and plant machinery.
This item is a pulley with a 220 mm diameter, 7 grooves and section B. Those three data points define the mounting: the 220 mm diameter, the number of grooves (7) and the belt section it corresponds to, B. The designation POLEA 220 7B summarizes exactly that. Since it is in-house manufactured, EMMAR brand, it is produced with the dimensional control that a belt drive requires: aligned grooves and a diameter within what section B requires.
Typical applications are drives where a shaft needs to be driven with several belts in parallel. It appears in centrifugal fans, screw compressors, centrifugal pumps, screens, mixers and transmission lines of industrial plants. It is also used as a replacement pulley in machines where a section B belt run already exists and the same number of grooves is to be maintained so as not to change the transmitted power.
To mount it, verify that the shaft has a diameter and keyway compatible with the pulley bore, and that the belt is section B. The number of grooves (7) must match the number of belts you are going to use: if you install fewer, the pulley runs unbalanced. Align the pulleys with a straightedge or an alignment laser and check the belt tension according to the equipment manual. If the pulley is going to rotate at high speed, it is advisable to balance it before mounting.
If you need an equivalent, the most practical thing is to send us the part number that appears on the part or on the drawing. With that data we check whether there is a pulley with a different number of grooves, another diameter or even another section that fits your drive. We can also evaluate a custom pulley if the shaft or keyway do not match the standard. The more data you give us (shaft diameter, number of grooves, belt section), the faster we respond.

Frequently Asked Questions
- What does it mean that it is in-house manufacturing, EMMAR brand?
- It means that the 220 7B pulley is produced by MR Accesorios Industriales, it is not from a third-party brand. That allows us to control the machining of the grooves and the diameter, and also to evaluate custom variants if your application requires it.
- Can I use belts of another section on this pulley?
- No. The pulley is made for section B belts. If you use another section, the groove does not seat properly and the belt wears quickly or slips. If you need another section, ask us about an equivalent pulley.
- How do I order a pulley with a different number of grooves or diameter?
- Send by WhatsApp the part number of the current pulley and the data of your drive: shaft diameter, belt section and number of grooves you need. With that we will quote you an in-house manufactured pulley with the size you are looking for.
