RINGSPANN SF series freewheels are power transmission components that allow rotation in one direction and lock in the opposite direction. They are used in applications where backstopping is required, such as lifting systems, inclined conveyors or intermittent indexing mechanisms. MR Accesorios Industriales sells this line as exclusive representative in Argentina, with technical advice to select the right model for the application.

The SF series designation is read with two numbers separated by a comma: the first indicates the nominal bore diameter and the second the width of the freewheel. For example, SF 18-13.5 SF corresponds to a freewheel with 18 mm bore diameter and 13.5 mm width. Models such as SF 23-13.5 SF or SF 31-13.5 SF share the same width, while others vary in their dimensions. The final SF suffix identifies the series and its design features.

These freewheels are used in industries such as food, cement, mining, port and material handling. In Argentina, they are commonly found in conveyor belts, bucket elevators, mills, mixers and lifting systems. They are also used in machine tools and automation equipment where reliable and repetitive unidirectional movement is required.

To select an SF freewheel, take into account the shaft diameter, the torque to be transmitted, the rotation speed and the environmental conditions. It is essential to verify the alignment between the shaft and the housing, and to ensure adequate lubrication according to the type of sealing. Installation must be carried out with appropriate tools to avoid damage to the internal bearings. If the application requires high precision, consult our technical team.

RINGSPANN SF series freewheels can be interchanged with equivalent products from other brands, but it is essential to verify the critical dimensions and load capacities. Not all freewheels are directly interchangeable; factors such as bearing type, sealing and permissible torque may vary. Therefore, we always recommend validating compatibility before replacing a component.
