RINGSPANN freewheels of the FA SFT series are power transmission components that allow rotation in one direction and lock movement in the opposite direction. They are used to prevent backrunning, as backstop devices or to engage and disengage shafts depending on speed. MR Accesorios Industriales sells them in Buenos Aires, Argentina, as exclusive representative of RINGSPANN in the country.

The FA SFT series designation combines the size with the design type. In the examples FA 37 SFT, FA 57 SFT, FA 82 SFT and FA 107 SFT, the number indicates the construction size of the freewheel and the letters SFT identify the series variant. The higher the number, the larger the size and torque transmission capacity. To choose the right model, that code must be matched against the actual application conditions.

These freewheels are used in equipment where reverse rotation must be prevented or a load must be held: inclined belt conveyors, bucket elevators, gearboxes, pumps, fans and process machines. In Argentine industry they appear in food, cement, mining, port and aggregate processing plants, where a shaft backrunning can damage the equipment or create an unsafe condition.

To select a freewheel, the torque to be transmitted, the rotation speed, the free rotation direction and the mounting type must be taken into account. Lubrication, sealing against dust or moisture and alignment between shafts also matter. Misaligned mounting or insufficient lubrication shortens the mechanism's life, so it is advisable to review these points before defining the model.

Freewheels are interchanged between manufacturers by part number, size and mounting type, but there is no universal equivalence: each brand defines its own dimensions and capacities. Therefore, before replacing a unit, it is advisable to compare the original part number, the size and the service conditions.
