The 400 7B is a V-belt pulley with a 400 mm outside diameter, 7 grooves and Section B. Manufactured by EMMAR, it is built for drives that distribute power from one line to multiple shafts. Common in mills, mixers and conveyor systems, it can be customized with different bore and fastening options because it is made in-house.

This pulley is cast in iron or steel, depending on the application, and its grooves are machined for Section B belts. The 7-groove design allows more torque to be transmitted than a single-groove pulley while keeping the same diameter. It mounts on a keyed shaft and is secured with a set screw or taper, according to the equipment design. As an in-house EMMAR product, the bore diameter and fastening type can be adjusted to your requirements.

Typical uses include equipment where power must be split among several shafts: mills, mixers, conveyor belts, blowers, pumps and compressors. It also appears in agricultural machinery and production lines that need synchronized speeds. With 7 grooves, it suits drives requiring high pulling capacity with Section B belts. In tight spaces, a single 400 mm 7-groove pulley can replace two smaller pulleys.

When selecting the 400 7B, consider shaft speed, power to be transmitted and the minimum pulley diameter allowed by the belt. Verify that the bore and keyway match the shaft and that center distance permits the belt. Balancing matters at higher speeds and should be checked. For dusty or humid environments, choose an appropriate surface treatment. MR can manufacture the pulley with the bore and fastening you need.
