The 420 2C pulley is a section C V-belt drive pulley, with a 420 mm diameter and two grooves. It is used to transmit power between parallel shafts in industrial equipment, where a stable transmission ratio and good belt grip are needed. Being in-house manufactured, EMMAR brand, the groove machining and balancing are controlled so that the pulley runs without vibration and with even wear.

This item is a pulley with a 420 mm diameter, 2 grooves and section C. The designation POLEA 420 2C summarizes those three variables: the outer diameter, the number of grooves and the belt profile it accepts. Section C corresponds to wide-profile V-belts, typical of drives with high loads. Having two grooves allows two belts to be mounted in parallel on the same hub, which distributes the effort and improves drive continuity.

Typical applications are power transmission equipment in industrial plants: fans, centrifugal pumps, compressors, conveyor belts and process machines. In all those cases the pulley is mounted on a shaft and receives the belt coming from the drive pulley. The section C and the 420 mm diameter orient it toward medium or low speed drives with considerable torque, where it matters that the belt does not slip and that the assembly stays aligned.

To select and mount this pulley, check that the shaft and keyway match the hub bore, and that the center distance allows the correct belt wrap angle. Check alignment between pulleys with a straightedge or laser before tensioning. Tension is adjusted according to the equipment manual or with a belt tension gauge. If the pulley runs with two belts, both must be from the same batch and tensioned equally to prevent one from working harder than the other.

If you need an equivalent pulley, send us the full part number, the number of grooves and the belt section you use. It also helps if you tell us the current diameter and the type of hub mounting. With that data we propose the corresponding in-house manufactured pulley or we machine it to measure. You don't need to have the data sheet on hand: the part number is enough to get started.
