The 420 1B pulley is a single-groove power transmission pulley designed for Section B V-belts. Manufactured in-house under the EMMAR brand, it is used to transmit motion between parallel shafts in industrial equipment ranging from machine tools to ventilation and conveying systems. Its construction and machining are controlled to support reliable operation in demanding applications.
With a 420 mm diameter and one groove for Section B belts, this pulley suits transmission layouts where a single belt is needed. Section B is common in industrial drives, and this pulley accepts that belt type directly. Because it is produced in-house, the machining and balancing steps are managed under the EMMAR brand to maintain consistent quality.
Typical uses include machine tools, compressors, centrifugal pumps, industrial fans and conveying systems. In these setups, the 420 mm single-groove pulley transfers power from a motor or gearbox to the driven equipment. It is often chosen where a specific speed is required and mounting space is limited. The single-groove design simplifies alignment and helps reduce the overall weight of the assembly.
When selecting this pulley, confirm the pitch diameter of 420 mm and that the belt is Section B. Proper alignment between the driving and driven pulleys is important to avoid premature wear on the belt and bearings. Also verify that the keyway and center bore match the shaft. If you need more grooves or a different diameter, we can manufacture it to your requirements.
To find an equivalent, send the code of the pulley you are replacing or the shaft and belt dimensions. With that information, we can identify the right pulley from our in-house manufacturing line or develop a custom solution. We can also help you choose the most suitable belt section based on the power and speed of your application.
