The 650 6C pulley is a V-belt drive pulley with section C, 650 mm diameter and 6 grooves. It is used to drive large shafts in equipment where power must be distributed across several belts and rotation speed kept with the least possible loss. It is in-house manufacturing, EMMAR brand, designed to replace worn pulleys or to build a new drive from scratch.

This item is a pulley with 650 mm diameter, 6 grooves and section C. The designation POLEA 650 6C sums up those three variables: the outside diameter, the number of grooves and the belt profile it houses. Section C corresponds to wide-profile V-belts, the ones used when a lot of power must be transmitted with few belts. The grooves are machined so that each belt seats evenly and works under the same tension.

It is found in drives for mills, mixers, high-flow pumps, industrial fans, screw compressors and process equipment in general. Also in machines in the food industry and in production lines where the motor is far from the driven shaft and that distance must be bridged with belts. With 6 grooves, it allows power to be staged: fewer belts can be fitted if the load is lower and the set completed when demand rises.

To choose it correctly, first identify the section of the belt you will use: it must be C. Then check the shaft diameter and the type of keyway or bushing the mounting requires, because the pulley is supplied according to the bore the equipment calls for. Also check the alignment between pulleys: a misalignment of a few degrees wears the grooves and belts within a few weeks. And check that the number of grooves matches the number of belts the drive will carry.

If you cannot find the exact part number or need a nearby size, send us the full designation, the shaft diameter and a photo of the old pulley. With that data we look for the equivalent or assess manufacturing it. We can also quote a pulley with a different number of grooves or a different diameter within the same section C, as long as the mounting allows it.

MR Accesorios Industriales manufactures this pulley and sells it along with the rest of the power transmission line. If you have the part number at hand, send it by WhatsApp and we will send you the quote with the technical data you need to confirm the replacement.
