The shrink disc is a shaft-hub connection component that transmits torque by friction, without a keyway or backlash. It is mounted on the hub and, when its screws are tightened, compresses the hub against the shaft, creating a rigid and removable connection. It is used in power transmission, gearboxes, machine tools and equipment where high precision and reliability are required. MR Accesorios Industriales supplies the RINGSPANN line in Buenos Aires, Argentina.
The designation of RINGSPANN shrink discs is organized by series and numeric codes. In the RLK 603 series, examples such as 4200-014301-000000, 4200-016301-000000 and 4200-020301-000000 show a structure where the middle digits identify size and configuration. The numeric suffixes differentiate variants of diameter, number of screws or mounting type. To select the correct model, it is essential to cross-check the complete part number with the shaft and hub dimensions. MR Accesorios Industriales can assist you in interpreting each reference.
These discs are used in industries in Argentina such as metalworking, food, cement, mining and petrochemical. They are found in gearboxes, pumps, fans, conveyor belts, machine tools and process equipment. Their ability to transmit high torque without a keyway makes them ideal for smooth shafts, where stress concentration or wear is to be avoided. They are also used in applications with reversing rotation or dynamic loads, where a friction-tightened connection offers advantages over traditional systems.
To select a shrink disc, the shaft diameter, the hub outer diameter, the torque to be transmitted and the environmental conditions must be considered. Mounting requires clean surfaces, screw lubrication as specified and progressive tightening in a cross pattern to avoid deformation. Alignment between shaft and hub must be careful; once tightened, the disc does not allow misalignment. Screw lubrication is key to achieving the correct tightening force. If in doubt, consult our technical team.
Regarding equivalents, RINGSPANN shrink discs can replace other shaft-hub connection systems from different brands, as long as the dimensions and torque capacity are respected. Direct interchangeability should not be assumed based on size alone; the geometry and tightening values must be verified. Each manufacturer defines its own tolerances and materials. Therefore, when looking for a replacement, it is essential to compare the technical specifications and consult a specialist.

Frequently Asked Questions
- What is a shrink disc?
- It is a shaft-hub connection that transmits torque by friction, without a keyway. It consists of an inner ring and an outer ring that, when the screws are tightened, compress the hub against the shaft. It allows rigid, removable and high-precision connections.
- How do I choose the right RINGSPANN model?
- You need to know the shaft diameter, the hub outer diameter and the torque to be transmitted. With that data, the part number that meets the requirements is selected. If you are not sure, write to us on WhatsApp with the measurements and we will advise you.
- Are RINGSPANN discs interchangeable with other brands?
- They can be if the dimensions and torque capacity match, but this should not be assumed without verification. Each manufacturer has its own tolerances and materials. Always compare the technical specifications before replacing. We can help you with the comparison.
