RINGSPANN FZ series freewheels are power transmission components that allow rotation in one direction and lock in the opposite direction. They are used to prevent backdriving, implement intermittent indexing or as a safety mechanism in industrial equipment. MR Accesorios Industriales supplies them in Buenos Aires, Argentina, with technical advice to select the right model for the application.
The FZ series designation is completed with a four-digit number that identifies the size and mounting characteristics. For example, models FZ 6201, FZ 6202 and FZ 6203 share the series but vary in dimensions and torque transmission capacity. Each code refers to a specific design within the RINGSPANN catalogue. To choose the right one, it is essential to know the required torque, rotation speed and the type of coupling to the shaft and housing.
These freewheels are used in a wide range of industries in Argentina: from conveyor belts and bucket elevators to machine tools, pumps, gearboxes and packaging equipment. They are also used in safety systems to prevent reverse rotation in mills, mixers and fans. Their function is critical in processes where backdriving can damage the product, the machine or create risks for personnel.
To select an FZ freewheel, take into account the nominal and starting torque, maximum speed, free and locked rotation direction, and environmental conditions. Mounting requires precise alignment between shaft and housing to avoid parasitic radial loads. Proper lubrication and sealing against dust and moisture extend service life. In demanding applications, a load and duty cycle analysis may be necessary.
RINGSPANN freewheels can be interchanged with equivalent products from other brands, but the equivalence is not direct: mounting dimensions, permissible torque, limiting speed and internal bearing type must be compared. Matching the shaft diameter alone is not enough. Therefore, it is always advisable to verify functional compatibility before replacing a unit. MR Accesorios Industriales can guide you through that technical comparison.
If you need a RINGSPANN FZ series freewheel, write to us via WhatsApp with the complete code (for example, FZ 6201) or with the application data. We will quote you shortly and advise you so you choose the correct variant. MR Accesorios Industriales, more than 80 years supporting Argentine industry.

Frequently Asked Questions
- How do I identify the RINGSPANN freewheel model I need?
- The complete code, such as FZ 6201, FZ 6202 or FZ 6203, identifies the size and characteristics. If you do not have it, send us the shaft dimensions, required torque and rotation direction. With that data we can guide you to select the right variant.
- What applications do FZ series freewheels have?
- They are used in drives where one-way rotation is needed: conveyor belts, elevators, machine tools, pumps, gearboxes and backstop safety systems. In Argentina, they are common in food, chemical and metallurgical plants.
- Can RINGSPANN freewheels be replaced by other brands?
- Yes, equivalents from other brands exist, but interchangeability requires comparing dimensions, permissible torque, speed and mounting type. Shaft diameter alone is not enough. Send us the code and the application so we can help you evaluate the right alternative.
