The 200 4A pulley is a V-belt drive pulley, section A, with a 200 mm diameter and 4 grooves. It is used to drive shafts from a motor, reducing or increasing speed depending on the combined diameters. It is an in-house manufactured part, EMMAR Accesorios Industriales brand, designed for equipment working with moderate loads that needs a stable and repeatable drive over time.

This item is a pulley with a 200 mm diameter, with 4 grooves for section A belts. The designation POLEA 200 4A summarizes those three variables: size, number of grooves and section. The 200 mm diameter corresponds to the pulley's nominal size, and the 4 grooves allow mounting up to four belts in parallel on the same body. Section A defines the groove profile that seats the belt. It is an in-house manufactured part, EMMAR brand, not a resold item.

Typical applications appear in machines that need to transmit motion between a motor and a working shaft: fans, compressors, centrifugal pumps, light conveyor belts, mixers and factory equipment. It is also used to replace worn or broken pulleys, when the original drive ratio is to be maintained. With 4 grooves, it accepts configurations of two, three or four belts depending on the power to be transmitted and the available space.

To mount and select this pulley correctly, first check the shaft diameter and the type of fastening (keyway, set screw or taper bushing, as applicable). Then confirm that the belt section is A and that the number of grooves matches the number of belts you will use. Alignment between the driving and driven pulleys is key: misalignment accelerates wear on the belt and the grooves. It is also advisable to check the condition of the grooves before mounting a new belt.

If you need an equivalent pulley or a nearby size, the most practical thing is to send us the part number POLEA 200 4A or the diameter and number of grooves you are looking for. We can check whether a pulley of another size or section fits your drive, or whether it is better to manufacture it with the same characteristics. For that, also send us the shaft diameter and the type of fastening your equipment uses. That way we can quote you without delay.
