The 800 6B pulley is a V-belt drive pulley, manufactured by EMMAR in section B with 6 grooves and 800 mm diameter. It is used to drive large shafts in equipment that works with high drive ratios and needs to dissipate heat. Because it is in-house manufacturing, the machining can be adjusted to the size and keyway type required by each piece of equipment. It mounts on cylindrical shafts and is aligned with the drive pulley to distribute the load across the six grooves.

This item is a pulley with 800 mm diameter, 6 grooves and section B. Section B defines the groove profile for V-belts of that size, and the 6 grooves allow more power to be transmitted than a pulley with fewer grooves of the same diameter. The 800 mm diameter places it among large pulleys, designed for low-speed, high-torque shafts. It is manufactured by MR, with in-house machining, which makes it easy to repeat the part or adapt the bore and keyway to the shaft size.

It is used in drives for mills, mixers, screens, high-flow pumps, industrial fans and lifting equipment. It also appears in process lines where speed must be reduced and torque increased, or where the drive shaft turns at low revolutions and a large pulley is needed to match that speed. In food, chemical and mineral plants, this type of pulley is chosen for its ability to work with several belts and distribute the load, which extends the service life of the assembly.

To mount it, check that the bore and keyway match the shaft, and that the pulley is aligned with the drive pulley: a misalignment of a few degrees wears the belts and grooves. Tension is adjusted according to the belt type and the center distance; it is best to check it with a tension gauge or by deflection. When selecting, take into account the power to be transmitted, the shaft RPM and the pitch diameter, because the number of grooves and the section depend on that. If the original equipment has another size, an equivalent pulley can be evaluated.

If you need the same pulley with another diameter, another number of grooves or a different bore, send us the part number or the shaft size and we will review it. We can also manufacture a custom pulley if the equipment does not accept a standard one. To request a nearby size pulley, send us the outside diameter, the section and the current grooves, and we will tell you what in-house manufacturing options we have. The idea is for the pulley to fit without modifying the shaft or the drive system.

To request a quote, write to us on WhatsApp with the part number POLEA 800 6B or with the designation shown on the equipment nameplate. If you have doubts about the section or the grooves, send a photo of the old pulley and the shaft dimensions. MR Accesorios Industriales manufactures this pulley and can adjust the machining according to what you need. The reply includes the quote and technical advice, with no obligation.
