The 280 mm diameter, 1 groove, section C pulley is a power transmission component that is mounted on a machine shaft to receive a V-belt. Its function is to transmit rotary motion from the motor to the driven equipment, maintaining the transmission ratio and alignment. It is a key part in systems where robustness and continuous operation are needed, and for that reason it is manufactured with dimensional control to ensure a correct fit with the belt and the shaft.

This item is a pulley with a 280 mm diameter, 1 groove and section C. Section C corresponds to a V-belt profile larger than sections A and B, suitable for transmitting higher power. The machined groove guides the belt and prevents it from coming off during rotation. The pulley is manufactured at MR with materials and processes that give it resistance to wear and repeated loads. The outer diameter and groove width are controlled so that the belt seats evenly and does not slip.

It is used in belt drive equipment where a single drive line is required, such as industrial fans, compressors, centrifugal pumps, conveyor belts and machine tools. It also appears in drive systems for mills, mixers and process equipment. Because it is section C, it is common in installations that handle medium to high power and where the belt must have good traction capacity. It is a common replacement part in industrial maintenance.

To mount it, check that the shaft has the diameter and key suitable for the pulley bore, and that the belt is section C. The alignment between drive and driven pulleys must be correct to avoid uneven belt wear and vibration. Tension is adjusted according to the equipment manual or the belt manufacturer's recommendations. If the pulley runs at high revolutions, balancing should be checked. At MR we manufacture this pulley, so we can advise you on the size and machining of the bore.

If you need a pulley with another number of grooves, another diameter or a different section, we can evaluate manufacturing a nearby size.
