The POLEA 320 2B from EMMAR is a V-belt pulley with a 320 mm diameter and two grooves for section B belts. It is designed to transfer power between parallel shafts in industrial machinery where a consistent transmission ratio and reliable belt grip are needed. Because EMMAR manufactures it in-house, the machining and balancing are controlled, so the pulley runs smoothly in continuous operation.

The part number POLEA 320 2B tells you the key specifications: a 320 mm outer diameter, two grooves, and a section B profile. Section B is a classic V-belt size; the belt sits in the groove and transmits power through its flanks. The grooves are machined to seat the belt evenly and keep it from coming off during running.

You will find this pulley in belt drives for machine tools, compressors, fans, pumps, conveyors, and process equipment. It also appears in gearboxes and transmission systems that need multiple belts to share the load. Two grooves allow the drive to handle more power than a single-groove pulley at the same diameter, which helps when space is tight and you need a specific speed ratio.

When mounting, verify that the shaft diameter and tolerance match the pulley bore, and that the keyway aligns. Use a straightedge or laser to align the pulleys and prevent uneven belt wear. Set tension according to the belt manufacturer's recommendation: too loose and the belt slips, too tight and you overload the bearings. If you are replacing an existing pulley, compare pitch diameter, number of grooves, and section before ordering. Clean grooves also help performance.

If you need a different size, number of grooves, or section, this pulley can be manufactured to order. Just provide the diameter, groove count, section, and the type of keyway or fixing you require. We can also help you find an equivalent for a pulley from another brand. The more details you send, the faster we can respond.
