The 400 7B pulley is a V-belt drive pulley manufactured by EMMAR Accesorios Industriales. It has a 400 mm diameter, 7 grooves and Section B, which makes it suitable for driving several shafts at once from a single line. It is used in machines that need to distribute power between different points, such as mills, mixers or conveyor lines. Because it is in-house manufactured, machining and balancing variants can be requested.

This pulley has a 400 mm outside diameter, 7 grooves and Section B. It is a cast iron or steel pulley, depending on the application, with machined grooves for Section B V-belts. The number of grooves allows more torque to be transmitted than a single-groove pulley, while keeping the same diameter. It is mounted on shafts with a keyway and secured with a set screw or taper, depending on the equipment design. Because it is in-house manufactured, EMMAR brand, the bore diameter and the type of fastening can be adjusted.

It is used in equipment where power must be distributed between several shafts: mills, mixers, conveyor belts, blowers, pumps and compressors. Also in agricultural machinery and in production lines that need to synchronize speeds. With 7 grooves, it is common in drives that require high pulling capacity with Section B belts. If the equipment has little space, a 400 mm pulley with 7 grooves can replace two smaller pulleys.

To choose it correctly, take into account the shaft speed, the power to be transmitted and the minimum pulley diameter allowed by the belt. Check that the bore and keyway match the shaft, and that the center distance allows the belt. Balancing is important if the pulley rotates fast: it should be checked. If the pulley is going to work in a dusty or humid environment, choose the appropriate surface treatment. MR can manufacture the pulley with the bore and fastening you need.
