This 650 mm diameter, 6-groove, section B pulley is a power transmission component that mounts on a shaft and drives V-belts. The combination of diameter and groove count suits applications that need a specific ratio and the capacity to run several belts side by side. MR Industrial Accessories builds it in-house, with dimensional checks on each unit.

The pulley has a 650 mm diameter, 6 grooves, and a section B profile. Section B sets the groove shape for that V-belt type, while the six grooves let you install six belts in parallel on the same body. Diameter controls the transmission ratio and the peripheral speed for a given shaft speed. The part is produced at MR Industrial Accessories, where key dimensions are verified before it leaves the shop.

Use it where power moves from a motor or gearbox to a driven shaft: industrial fans, compressors, centrifugal pumps, mills, screens, and conveyors. It also appears in continuous-process machines as part of a multi-belt drive. In those setups, groove count and diameter set the drive capacity and the final speed of the equipment.

When selecting, consider the pitch diameter, number of grooves, and belt section you plan to use. Confirm the shaft diameter and the keyway or fastening method, and check alignment with the drive pulley to prevent uneven belt wear. For high-tension or variable-load service, inspect groove condition and balance before mounting.

For an equivalent pulley, send the full part number, section, number of grooves, and diameter from the equipment plate or the original part. With that information, we can propose a pulley with similar characteristics or manufacture one to your dimensions. We can also advise on belt type and installation if you send a photo of the drive.
