further informations
Wherever there is a requirement to connect shaft and hub safely and quickly, the hydraulically tensionable shrink discs type “SHS” from TAS Schäfer GmbH are used. With the TAS-SHS series, TAS Schäfer GmbH has developed a hydraulically tensionable shrink disc type “SHS”, which is used everywhere in drive technology for frictional shaft-hub connections. Due to its fast and safe clamping, it is particularly suitable for assembly on test benches and repetitive clamping operations. Furthermore, the SHS series impresses with its unique selling points, such as low pressure required for clamping, customer-side performance of maintenance and repair work, and the possibility of adapting the inner ring to different sizes.
Further development and the fulfillment of specific customer requirements as well as the highest quality standards are indispensable prerequisites in modern manufacturing today.
The TAS-SHS product range has been used thousands of times in many applications for years. All over the world, especially in wind turbines, on hydraulic motors and in gear test benches, hydraulically tensionable shrink discs of the “SHS” design can be found. The main function of a hydraulically tensionable shrink disc type “SHS” is to securely connect a shaft to a hub by means of frictional locking. For example, between a drive shaft and a transmission hollow shaft. The hydraulically tensionable shrink disc creates a backlash-free connection by pressing the hub onto the shaft. This type of connection is mainly used to transmit torque. The hydraulically tensionable shrink disc of the “SHS” series only provides the required forces and does not itself transmit any forces or torques between the shaft and hub. It is therefore not in the flow of forces. In the SHS products of TAS Schäfer GmbH, the basic principle of the mechanical, three-part shrink disc has been retained. This principle has been tried and tested for a long time. Here, the force-transmitting friction surfaces are strictly separated from the hydraulic system. This strict separation prevents oil contamination of these surfaces.
Advantages of hydraulic shrink discs
Wherever there is a requirement to connect shafts and hubs safely and quickly, the hydraulically clampable shrink discs type ‘SHS’ from TAS Schäfer GmbH are used. With the SHS series, TAS Schäfer GmbH has developed a hydraulically clampable shrink disc that is used everywhere in drive technology for friction-locked shaft-hub connections.
Thanks to its fast and secure clamping, this shrink disc is particularly suitable for installation on test benches and the repetitive clamping processes that take place there. However, the hydraulic shrink disc is also used worldwide in industrial applications where, for example, quick disassembly and assembly is required during the maintenance process of a system in order to reduce downtimes.
The SHS series also impresses with its unique selling points, such as the low pressure required for clamping, the fact that maintenance and repair work can be carried out by the customer and the possibility of adapting the inner ring to different sizes.
Further development and the fulfilment of specific customer requirements as well as the highest quality standards are essential prerequisites in modern production today.
The hydraulic shrink discs from TAS Schäfer have been used thousands of times in many areas of application for years. Hydraulic shrink discs of the ‘SHS’ design can be found all over the world, especially in wind turbines, in cement production, on hydraulic motors and in gearbox test benches. The main function of a hydraulic shrink disc type ‘SHS’ is to securely connect a shaft to a hub by means of frictional locking.
For example, between a drive shaft and a hollow gearbox shaft. The hydraulically tensionable shrink disc creates a backlash-free connection by pressing the hub onto the shaft. This type of connection is mainly used to transmit torques. The hydraulically tensionable shrink disc of the ‘SHS’ series only provides the required forces and does not itself transmit any forces or torques between the shaft and hub. It is therefore not in the power flow. The basic principle of the mechanical, three-part shrink disc has been retained in the SHS products from TAS Schäfer GmbH. This principle has been tried and tested many times over. The force-transmitting friction surfaces are strictly separated from the hydraulic system. This strict separation prevents oil contamination of these surfaces.
Compared to a mechanical shrink disc, a hydraulic shrink disc can save up to 95% of the assembly time. This results in enormous potential savings for our customers.

Applications for hydraulic shrink disc SHS
Different requirements call for different solutions. True to this motto, TAS Schäfer has developed two different concepts for hydraulic shrink discs. The hydraulic shrink discs ‘SHS-P’ and ‘SHS-PA’ were developed for the area of transmission test benches, where frequent clamping and unclamping is a basic requirement.
Optimised for this specific application, these hydraulic shrink discs can meet the requirements of demanding environments such as transmission test benches. They are designed to withstand repeated loads while ensuring reliable and precise fastening.
The bayonet system developed offers ease of use for test bench personnel and allows the operator to quickly lock and unlock the shrink discs without the need for additional tools. This increases productivity and minimises downtime, which is crucial for the efficient performance of tests on the test bench. Every second saved counts here.
We also offer our customers the right solutions for industrial applications. A robust design and powerful load transmission are the main features of hydraulic shrink discs in this design. This ensures reliable performance and minimises the risk of failure or damage to entire industrial plants. For difficult environmental conditions, TAS Schäfer offers various protective measures for the hydraulic shrink discs. This ensures a high level of reliability. This is crucial for the safety and efficiency of industrial gearboxes, which often operate continuously under extreme conditions.
