The POLEA 350 2B pulley is a power transmission component manufactured by EMMAR Accesorios Industriales. It is used to transmit motion between shafts using V-belts of section B, with two grooves that allow mounting two belts in parallel. Its 350 mm diameter places it among medium to large pulleys, suitable for moderate transmission ratios and for applications requiring some inertia and drive capacity.

This item is a pulley with 350 mm diameter, 2 grooves and section B. The designation POLEA 350 2B summarizes these three characteristics: the outside or pitch diameter of 350 mm, the number of grooves (two) and the belt profile it accepts, section B. It is manufactured by EMMAR, which allows controlling the machining of the grooves and balancing. It is not a generic pulley: it is produced according to the customer's needs and identified with the code MR-POLEA-B2-350.

Typical applications of this type of pulley include medium-power machines, such as screw compressors, industrial fans, centrifugal pumps, conveyor belts and transmission equipment in process plants. It is also used in the field, in agricultural implements and in maintenance workshops that replace worn pulleys or modify transmission ratios. Having two grooves allows doubling the torque capacity or maintaining alternative operation if one belt fails.

To correctly mount this pulley, verify that the shaft has the appropriate diameter and keyway, and that the central bore matches the fastening system (key, set screw or taper bushing). Alignment between pulleys is critical: misalignment accelerates wear on belts and grooves. When selecting, take into account the power to be transmitted, the shaft RPM and the desired transmission ratio. Section B accepts standard V-profile belts, and the number of grooves defines how many belts you can mount.

If you need an equivalent pulley or a nearby size, the most practical thing is to send us the code POLEA 350 2B or MR-POLEA-B2-350 via WhatsApp. You can also indicate the shaft dimensions, belt section and required number of grooves, and we will quote a custom pulley. We work with in-house manufacturing, so we can adjust the diameter, bore and number of grooves according to your application.
