The 800 6C pulley is a large-diameter industrial pulley with six grooves for section C belts, manufactured by MR Accesorios Industriales. It is used in power transmissions that need to distribute the load among several belts, such as mills, crushers, high-flow fans and continuous process equipment. Its 800 mm diameter and six grooves allow it to handle high torques at a moderate rotation speed, provided the shaft and the mounting are prepared for that size.

This item is a pulley with an 800 mm diameter, 6 grooves and section C. The designation POLEA 800 6C summarizes those three variables: size, number of grooves and belt profile. Section C corresponds to a belt profile that is wider and taller than sections A or B, designed to transmit more power per groove. With six grooves, the pulley allows the load to be distributed among six belts, which reduces the individual tension and improves the service life of the assembly. It is an in-house manufactured part, EMMAR brand, not a third-party product.

Typical applications for a pulley of this size appear in low-speed, high-torque equipment: ball or hammer mills, crushers, screens, high-flow industrial fans, slurry pumps, mixers and main drives of process plants. It is also used in machines that start under load, where multiple belts help absorb torque peaks. In all cases, it is advisable to verify that the 800 mm diameter is compatible with the available space and with the desired transmission ratio.

To mount and select this pulley, take into account the shaft diameter and the type of fixing (keyway, taper bushing or press fit). Check the alignment between pulleys and the belt tension: with six grooves, a poorly tensioned belt unbalances the load distribution. Also check the permissible peripheral speed for the 800 mm diameter and the pulley material, and make sure the shaft support and bearings tolerate the weight and radial forces. If the equipment works with reversing rotation or pulsating loads, consult the drive calculation.

If you need an equivalent pulley or a nearby size, send us the code POLEA 800 6C or the data of the original pulley: diameter, number of grooves, section and shaft diameter. With that data we can evaluate an in-house manufactured pulley with the same performance or a compromise variant. We can also review whether it is advisable to move to a different number of grooves or a different diameter to adjust the transmission ratio. The idea is that you do not buy blindly: mechanical compatibility is confirmed first.
