RINGSPANN freewheels of the FBL LZ series are power transmission components that allow rotation in one direction and lock in the opposite direction. They are used to prevent backstopping, control indexing and protect equipment. MR Accesorios Industriales supplies them in Buenos Aires, Argentina, as exclusive representative of RINGSPANN. If you need one, send the code on WhatsApp and we will quote you promptly.

The FBL LZ series designation is read in parts: FBL identifies the family of complete freewheels, the number that follows —as in FBL 57 LZ or FBL 72 LZ— indicates the construction size, and the suffix LZ distinguishes the mounting or sealing variant. That combination defines the housing and shaft dimensions. To select the correct freewheel, have the complete code and the service conditions at hand: torque, speed and free rotation direction.

These freewheels are used in industries in Argentina such as food, cement, mining and logistics. They are present in belt and roller conveyors, bucket elevators, mills, mixers and machine tools. Their typical function is to prevent the backstopping of an inclined load, allow indexing in one direction or act as a safety device against reversal of motion. They are also mounted in auxiliary drive systems and in equipment where a drive shaft needs to be disengaged.

To choose an FBL LZ freewheel, check the torque it must transmit, the free rotation speed and the maximum shaft revolutions. Check the type of sealing and the intended lubrication: an environment with dust or humidity requires additional protection. Mounting must ensure alignment between the shaft and the housing; excessive eccentricity accelerates roller wear and reduces service life. Follow the manufacturer's instructions for tightening and start-up, and check the rotation direction before connecting the load.

Regarding equivalents, freewheels are compared between brands by their mounting dimensions, admissible torque and type of internal bearing. There is no universal direct replacement table: each manufacturer defines its own nomenclature and tolerances. If you need to replace a freewheel from another brand, send us the code and the main dimensions, and at MR Accesorios Industriales we will help you find the equivalent RINGSPANN option. Interchangeability must always be validated with the equipment's technical data.

To request a quote for a RINGSPANN FBL LZ freewheel, write to us on WhatsApp with the exact code —for example, FBL 57 LZ or FBL 72 LZ— and the quantity you need. If you cannot find the variant on the site, send us the model or the dimensions and we will reply promptly. We serve from Buenos Aires, Argentina, to the whole country.
