The 800 7B V-belt pulley from EMMAR is built for drives that need to move power between parallel shafts. It measures 800 mm in diameter and carries 7 grooves sized for section B belts. Mills, pumps, fans and conveyors are among the usual places this pulley shows up. Multiple belts can run side by side on it, which spreads the load across the grooves and helps cut down on wear.

The part number breaks down simply: the 7 tells you how many grooves are cut into the face, and the B tells you which V-belt section fits those grooves. With an 800 mm diameter, this is a large pulley, so it suits drive ratios that call for a big step between shafts and for jobs where several belts share the power. Because EMMAR produces these pulleys in-house, the dimensions and balance are kept under control for steady running.

You will find this size on equipment where the shafts sit far apart or where a substantial speed reduction is needed. Mixers, centrifugal pumps, induced draft fans, belt conveyors and other process machinery are common homes for it. The 7 grooves let you mount several section B belts at once, so you can fine-tune the transmitted power by changing how many belts are installed, and you gain some redundancy if one belt needs attention.

When you pick a pulley like this, work from the pitch diameter, the groove count, the belt section and the shaft connection — whether that is a keyway or a taper bushing. Line the pulleys up with each other and set belt tension correctly to avoid early wear. If a taper bushing is used, confirm it matches the shaft diameter. It also pays to clean the grooves and check runout before putting the drive back in service.

Need a different groove count, another diameter or a different belt section? Since EMMAR handles its own manufacturing, the pulley can be adapted to your requirements. Send the part number or the dimensions from your equipment nameplate and we will quote an equivalent. We can also help you match the right belt to the application.
