The shrink disc is a shaft-hub connection element that transmits torque by friction, without a keyway or forced fit. It is mounted on the hub and, when its screws are tightened, compresses the hub against the shaft uniformly. It is used in power transmission when a detachable, centered connection with high load capacity is required. MR Accesorios Industriales carries this RINGSPANN line in Buenos Aires, Argentina, with technical advice to choose the size according to the shaft and torque.

The designation of these shrink discs combines a size number with an alphanumeric code. In the RLK 608 E series, the first numeric block identifies the assembly size and the suffix E distinguishes the execution variant. Examples 4200-016801-E00000, 4200-018801-E00000 and 4200-024801-E00000 show how the size changes within the same family. To select the correct one, provide the full part number shown on the drawing or on the machine: with that data the exact variant is identified.

These connections are used in equipment where the shaft and hub must be perfectly centered and transmit torque without backlash. They appear in gearboxes, pumps, fans, conveyor belts, mixers and machine tools. In Argentine industry they are common in food, cement, petrochemical and aggregate processing plants, where maintenance downtime is avoided with reliable connections. They are also chosen to replace worn keyways or to mount pulleys, gears and couplings on smooth shafts.

To select the disc, start from the shaft diameter and the torque to be transmitted, and verify that the surface pressure is compatible with the hub material. Assembly requires cleaning and degreasing the contact surfaces, checking concentricity and tightening the screws in a cross pattern and in stages up to the specified torque. Screw lubrication influences the actual tightening force. Careful alignment and progressive tightening prevent deformation and ensure the connection works without slipping.

Shrink discs are interchanged between brands by function and dimensional range, not by part number: each manufacturer uses its own nomenclature. When comparing alternatives, verify shaft diameter, outer diameter, width, allowable torque and screw type. RINGSPANN is an exclusive representative in Argentina through MR Accesorios Industriales, which can advise you on the equivalent variant within the line. Do not replace one disc with another without checking these parameters: a difference in capacity can compromise the connection.

If you already have the shrink disc part number, the drawing or a photo of the nameplate, send it by WhatsApp to MR Accesorios Industriales. With that data the corresponding RINGSPANN variant is identified and the quote is prepared promptly. If you are looking for a size that does not appear in the list, write to us with the shaft diameter and working torque: the technical team reviews the complete line and replies with the right option.
