The POLEA 130 3A is a V-belt pulley from EMMAR, manufactured in-house, with a 130 mm diameter and three grooves for section A belts. It transmits torque between parallel shafts in industrial machinery where a fixed ratio is required. The three grooves let you distribute the load across three belts, adding capacity without changing the pulley diameter.

The part number POLEA 130 3A tells you the three key variables: diameter, groove count and belt profile. The 130 mm diameter sets the ratio when paired with another pulley in the same drive. Section A is a standard industrial belt profile, and the three grooves accept three belts running side by side on one body.

You will find this pulley on machine tools, compressors, fans, centrifugal pumps, conveyors and process equipment. It also appears in speed reducers and multipliers that need a fixed ratio between two shafts. Drives that demand more power than a single-groove setup often use a three-groove pulley while keeping the same diameter.

Before mounting, check that the shaft diameter matches the pulley bore and that the keyway is in good condition. Align the pulleys with a straightedge or laser alignment tool to prevent uneven belt wear. Set belt tension according to the equipment manual or with a tension gauge. When replacing an existing pulley, compare the number of grooves, the section and the diameter.

If you need a different groove count, diameter or section, EMMAR's in-house manufacturing line can produce it. Send the part number POLEA 130 3A or the original pulley designation by WhatsApp, along with a photo of the part and the shaft measurement. With that information, the equivalent is confirmed.
