RINGSPANN FNR series freewheels are power transmission components that allow rotation in one direction and lock movement in the opposite direction. They are mounted on shafts and housings for backstop, indexing or one-way coupling functions. MR Accesorios Industriales sells them in Buenos Aires, Argentina, with technical advice to select the right model for the application.

The FNR series designation is read with the fixed letters and a number indicating the size. For example, the part numbers in the FNR series correspond to different sizes within the same family. The higher the number, the greater the torque transmission capacity and the outer dimensions. The numeric suffix does not indicate the diameter or the width; that data comes from the drawing or the data sheet of the specific model. To identify the exact variant, send the full part number.

These freewheels are used in industries such as food, cement, mining, petrochemical and materials handling. In Argentina, they appear on belt conveyors, bucket elevators, gearboxes, machine tools and pumping equipment. Their typical function is to prevent a shaft from running back or to allow movement in one direction only, protecting motors and mechanisms. They are also used in indexing systems and in couplings that require free rotation in one direction.

To select an FNR freewheel, take into account the torque to be transmitted, the rotation speed, the locking direction and the environmental conditions. Installation requires shafts and housings with suitable tolerances, correct lubrication and precise alignment to avoid parasitic loads. The sealing protects against dust and moisture, but it must be chosen according to the environment. If the equipment operates with vibration or high temperatures, consult our technical team to validate the configuration.

RINGSPANN freewheels can be interchanged with equivalent products from other brands, but interchangeability is not automatic: the mounting dimensions, rated torque, limiting speed and type of internal bearing must be verified. It is not enough for the part number to be similar. At MR Accesorios Industriales we help you compare alternatives and determine whether a replacement is viable. It is always advisable to start from the original part number and the actual operating conditions.
