The EMMAR POLEA 130 7B is a V-belt drive pulley built in-house by MR Industrial Accessories. Its code tells you the essentials: a 130 mm diameter, 7 grooves and a section B profile. Running several belts side by side lets the drive share the load across them while holding the speed ratio between the driving and driven shafts. If this pulley matches your equipment, send the part number over WhatsApp or email and the team will get you a quote.

Reading the designation is straightforward. POLEA 130 7B gives the diameter in millimeters, the groove count and the belt section, in that order. Section B is a general-purpose industrial V-belt profile, so the pulley takes B-section belts only. Seven grooves mean you can run seven belts in parallel, which raises the transmission capacity compared with a narrower pulley. The 130 mm diameter is what sets the speed ratio once it is paired with the other pulley in the drive. The part is cast iron and machined so each groove has the right angle and depth for the belt to seat properly.

You will find this type of pulley wherever V-belts carry power: compressors, fans, pumps, mills, mixers, conveyor drives and general transmission equipment. Agricultural machinery and implements running off a power take-off are another common home for it. In plants, it turns up on production lines that have to hold a steady speed. With seven grooves it suits medium and high power duties where one belt would not carry the load on its own.

On installation, check that the shaft diameter and keyway match and that the pulley sits with no play. Line the pulleys up so all the belts run in the same plane, since misalignment wears belts and grooves faster. Set belt tension as the equipment manual specifies. When replacing a pulley, compare diameter, groove count and section against the original before ordering.

If the exact size is not what you need, the team can look at an alternative. Different groove counts, diameters and sections are all possible, and a custom pulley can be made from the diameter, groove count and section you supply. For an equivalent, the quickest route is the original part number or a photo of the old pulley with a ruler alongside it, which is usually enough to identify the part and match it to the right option.
