RINGSPANN FN series freewheels are transmission components that allow rotation in one direction and lock in the opposite direction. They are used to prevent backrunning, control intermittent indexing or couple shafts as the mechanism requires. MR Accesorios Industriales sells them in Buenos Aires, Argentina, with technical advice to select the right model.

The FN series designation is read with the fixed letters and a number that indicates the size. For example, the part numbers in the FN series cover an increasing range of capacities. That number is not a diameter or a direct measurement: it identifies the size within the series and correlates with the mounting dimensions and the transmission capacity. To choose, you must always cross-check the part number with the manufacturer's data sheet.

These freewheels are used in equipment where load holding is needed, such as inclined conveyor belts, bucket elevators, gearboxes and intermittent-motion machines. In Argentine industry they appear in food, cement, steel and material handling plants. They are also used in auxiliary drive systems and in safety mechanisms that prevent reverse rotation.

To select an FN freewheel, you must consider the transmission torque, the rotation speed, the locking direction and the environmental conditions. Installation requires aligned shafts and clean surfaces; poor alignment accelerates wear. Lubrication must be the one specified by the manufacturer and the sealing protects against dust and moisture. In applications with variable loads, check the service factor.

RINGSPANN freewheels can be interchanged with equivalent products from other brands, but the equivalence is not automatic: you must compare mounting dimensions, permissible torque, limiting speed and internal bearing type. A similar part number is not enough. If you have the original part number or the housing dimensions, send us that data and we will help you find the compatible option.
