The 280 mm industrial pulley with one groove for a section A belt is a power transmission component that mounts on a machine shaft to transmit motion through a V-belt. It is used in equipment that needs a simple and reliable transmission ratio, such as fans, pumps, compressors and conveyors. MR Accesorios Industriales manufactures it with dimensional control to ensure correct belt fit and concentricity of the assembly.

This item is a pulley with a 280 mm diameter, 1 groove and section A. The designation POLEA 280 1A summarizes those three characteristics: the 280 mm outside diameter, a single groove and section A, which corresponds to V-belts with a narrow profile. The part is manufactured at MR with precision machining so that the groove has the correct angle and depth for the belt. Because it is in-house manufacturing, we can adjust the diameter and the number of grooves according to the equipment's needs.

Typical applications of a section A pulley with a single groove include machines that need to transmit moderate power at medium speeds: centrifugal fans, water pumps, air compressors, light conveyor belts and factory equipment. It is also used as a drive or driven pulley in systems where a fixed transmission ratio and simple maintenance are sought. Because of its 280 mm diameter, it is common on shafts up to 38 mm, although the bore is defined according to the order.

To select this pulley correctly, take into account the power to be transmitted, the shaft RPM and the type of section A belt. Check that the pitch diameter is compatible with the belt length and that the number of grooves matches the number of belts in the system. During mounting, ensure concentricity with the shaft and alignment with the driven pulley to avoid premature wear. If you need a pulley with more grooves or a different diameter, ask us and we will manufacture it.

If the part number POLEA 280 1A does not exactly match what you need, we can offer you a nearby size or an equivalent.
