The 280 1B pulley is a power transmission pulley of in-house manufacturing, EMMAR Accesorios Industriales brand, with a 280 mm diameter and one groove for a B-section belt. It is used to transmit motion from a motor or gearbox to a driven shaft, in machines that work with simple transmission ratios and V-belts. Its metal construction and machined groove allow correct seating of the belt and even wear in continuous service.

This item is a pulley with a 280 mm diameter, a single groove and B section, according to the designation POLEA 280 1B. Section B corresponds to a V-belt profile widely used in medium-power industrial transmissions. Having a single groove, the pulley handles one belt and is used in drives where parallel strands do not need to be added. MR manufactures it in its plant, with dimensional control over the diameter and the groove profile.

Typical applications of this type of pulley appear in fans, compressors, centrifugal pumps, light conveyor belts, mixers and factory equipment. It is also used to replace worn pulleys or to modify the transmission ratio of an existing machine, by changing the diameter of the driving or driven pulley. In all cases it is advisable to verify that the belt is B section and that the diameter is compatible with the permissible linear speed of the equipment.

To mount and select a single-groove B-section pulley, take into account the pitch diameter, the shaft diameter and the type of fastening (keyway, set screw or taper bushing, as applicable). The groove must be aligned with that of the opposite pulley to avoid uneven belt wear and vibrations. Also check the belt tension and the condition of the shaft bearings: a new pulley does not correct a previous misalignment. If the equipment works with variable loads, it is advisable to evaluate a larger diameter or more grooves.

If you need a pulley with another size, another number of grooves or a different section, you can request an equivalent within the same manufacturing line. For that, send us the current part number, the diameter, the number of grooves and the belt section, and we will confirm the corresponding reference. We can also manufacture to measure if the shaft or the keyway do not match the standard, as long as you send us the drawing or the relevant dimensions.
