The shrink disc is a shaft-hub connection component that transmits torque by friction, without a key or thermal interference. It is mounted on the hub and, when its screws are tightened, it compresses the shaft uniformly. It is used in power transmission, gearboxes, machine tools and rotating equipment. MR Accesorios Industriales supplies this RINGSPANN line in Buenos Aires, Argentina, with technical advice to select the size according to the shaft and the required torque.
The designation of these RINGSPANN discs combines a four-digit series number, a size code and an alphanumeric suffix. For example, 4200-044301-A01000 and 4200-050301-A01001 share the 4200 prefix and differ in the central block and the ending. That structure makes it possible to identify the construction variant and the dimensional range. To request a quote, send us the complete part number shown on the drawing or on the equipment nameplate.
They are used in industries in Argentina such as food, cement, steel, paper and mining, in equipment where high torque must be transmitted with moderate shaft and hub diameters. They also appear in pumps, fans, conveyor belts, mixers and machine tools. Because they do not require a keyway, they simplify the machining of the shaft and hub and allow more precise fits.
To select the correct disc, take into account the shaft diameter, the hub outer diameter, the torque to be transmitted and the type of load. Installation requires cleaning the surfaces, checking concentricity and tightening the screws in a cross pattern with a torque wrench, following the tightening value indicated for each size. Screw lubrication and the condition of the threads influence the clamping force and the repeatability of the installation.
RINGSPANN shrink discs can be interchanged with equivalent solutions from other European brands, as long as the shaft and hub dimensions, the permissible torque and the fastening method match. The diameter alone is not enough: surface pressure, the number and size of the screws and the hub material must be compared. If in doubt, send us the application data and we will help you validate the equivalence.
If you need to replace a shrink disc or build a shaft-hub connection for new equipment, write to us on WhatsApp with the part number or model shown on the drawing. At MR Accesorios Industriales we will reply shortly with the alternative that best fits your installation.

Frequently Asked Questions
- What is the difference between a shrink disc and a keyed connection?
- The shrink disc transmits torque by friction between shaft and hub, without a keyway. This avoids weakening the shaft, allows more precise fits and makes disassembly easier. A key, on the other hand, requires machining the keyway and concentrates stresses.
- How do I choose the shrink disc for my application?
- You need the shaft diameter, the hub outer diameter, the torque to be transmitted and the type of load. With that data the series and size are defined. If you have the part number of the original disc, send it and we will verify the equivalence.
- What care does installation require?
- Clean the contact surfaces, check concentricity and tighten the screws in a cross pattern with a torque wrench to the specified value. Thread lubrication and controlled tightening are key for the connection to work uniformly and safely.
