Industrial pulley 50 mm, 2 grooves, section A

EMMAR POLEA 50 2A belongs to pulleys, part of our Power transmission range. Tell us how many you need by WhatsApp or email and we'll get back to you promptly with a quote for POLEA 50 2A and any equivalents.

The POLEA 50 2A is a V-belt pulley with a 50 mm diameter and two grooves designed for section A belts. It is manufactured in-house under the EMMAR brand, which allows the machining and finish to be tailored to the requirements of each piece of equipment. This pulley is typically used to build or replace drives that need two belts without increasing the pulley diameter.

The designation POLEA 50 2A encodes the key specifications: 50 for the diameter in millimeters, 2 for the number of grooves, and A for the belt section. The grooves are machined so that the belt contacts the flanks rather than the bottom of the groove. As an in-house manufactured EMMAR part, it suits compact transmissions that require more than one belt on the same shaft.

You will find this pulley in low and medium power equipment such as fans, exhausters, small compressors, centrifugal pumps, light conveyor belts, woodworking machines, and mixers. It also serves as a replacement in older machines where the original size is no longer available. The two grooves allow higher torque transmission than a single-groove pulley of the same diameter, or continued operation with just one belt if the other fails and you need to keep running temporarily.

During installation, check that the shaft diameter and keyway type match the pulley bore, and that the drive and driven pulleys are aligned in the same plane. Adjust belt tension so that the belts deflect slightly when pressed with your thumb. When replacing an existing pulley, note the outside diameter, number of grooves, belt section, and bore diameter before ordering. With these details, you can confirm whether the POLEA 50 2A is the correct choice.

If you need a different diameter or additional grooves, you can request an equivalent or a custom pulley. To do so, send the original code, a photo of the part, and the shaft measurements. We also supply bearings, housings, chains, and seals, so if the replacement involves other components, they can be quoted together.

To request a quote for the POLEA 50 2A, send the code via WhatsApp or email. If you are unsure about the belt section or number of grooves, reach out anyway: with the designation and a photo of the equipment, we can quickly confirm whether this is the pulley you need or if another variant is required.
