The 420 1B pulley is a power transmission pulley, in-house manufactured, EMMAR Accesorios Industriales brand, designed to mount a Section B V-belt. It is used to transmit motion between parallel shafts in a wide variety of industrial equipment, from machine tools to ventilation and conveying systems. Its robust construction and precise machining ensure reliable operation and a long service life in demanding applications.

This pulley has a 420 mm diameter, a single groove and is designed for Section B belts. Section B is one of the most widely used in industrial power transmission, and this particular pulley allows a belt of that type to be mounted with full compatibility. The 420 mm diameter and the single groove make it suitable for specific transmission ratios where a single belt is required. Because it is in-house manufactured, EMMAR brand, all machining and balancing processes are controlled to guarantee a consistently high-quality product.

Typical applications for this pulley include machine tools, compressors, centrifugal pumps, industrial fans and conveying systems. In all these cases, the 420 mm pulley with one Section B groove allows the necessary power to be transmitted from a motor or gearbox to the driven equipment. It is commonly found in installations where a specific speed is required and mounting space is limited. Its single-groove design simplifies alignment and reduces the total weight of the assembly.

To select this pulley correctly, take into account the pitch diameter, which in this case is 420 mm, and check that the belt to be used is Section B. It is essential to ensure precise alignment between the driving and driven pulleys to avoid premature wear on the belt and the bearings. Also, check that the keyway and the center bore are compatible with the shaft where it will be mounted. If you need a pulley with more grooves or a different diameter, we can manufacture it to measure.

If you are looking for an equivalent or a nearby size, the most practical thing is to send us the code of the pulley you need to replace or the dimensions of the shaft and the belt. With that data, we can identify the right pulley within our in-house manufacturing line or develop a custom solution. We can also advise you on the most suitable belt section according to the power and speed of your application.
