Special Couplings – JAKOB:

Posted on June 11 2023

The German manufacturer JAKOB offers unique solutions for flexible bellows couplings.
JAKOB specializes in producing bellows couplings for over 40 years. The bellow coupling uses a thin-walled, flexible bellow to compensate for misalignment between the shafts and to absorb shock and vibration. The bellows are made of high-grade stainless steel or other materials depending on the application requirements. JAKOB's bellows couplings are known for their high torsional stiffness, zero backlash, and low maintenance requirements.

Special Couplings:

Distance couplings up to 6 meters in length.

The couplings are made of bellows and an intermediate tube, and their length and coupling interface can be customized to suit the drive or driven shaft.

Main features:

  • Variable length up to 6 meters
  • High torsional rigidity
  • Low moment of inertia
  • High speed capability
  • Temperatures up to 300°C.



Flexible couplings with a built-in safety mechanism - Torque Limiters

Safety couplings are designed to reduce costly damage to machines and prevent downtime by limiting torque and protecting against overload. In the event of excessive torque, the safety mechanism of the coupling disconnects from the drive shaft, preventing the transmission of torque to the drive system and minimizing the risk of damage to the machine.

This product provides a vital safeguard for your machinery, whether the error is due to improper operation, overload, faulty programming, or component failure.

The mechanism is entirely mechanical, and sensors can be integrated to detect an increase in torque and the disconnection of the coupling. This feature allows for swift fault detection, minimizing the potential impact on machine lifespan.

Moreover, the safety mechanism can be used for a variety of rotating components, such as wheels, gears, and flanges, adding an extra layer of protection to your machinery.

The engineers at Medital and the manufacturer's engineers would be happy to provide consultation and characterization for any technical requirement.

Stainless-Steel couplings

Stainless-Steel couplings are a reliable solution for applications requiring high resistance to corrosion, extreme temperatures, and harsh environments. JAKOB stainless-steel couplings are constructed from high-quality materials, ensuring a long lifespan and optimal performance even in the harshest conditions.

Here are some of the main features of our stainless-steel couplings:

  • Temperature range: -40°C to +350°C
  • Torque range: 1.5 - 1200 Nm
  • Inner diameter range: 7 - 85 mm
  • Long service life

Whether you need a flexible coupling for industrial equipment, food processing machinery, or other applications, our stainless-steel couplings provide the durability and reliability you need.


Special interfaces

JAKOB provides a range of flexible couplings with special and customized interfaces suitable for different drive systems.

These interfaces include couplings with:

  • Output shaft
  • Flange
  • DIN-EN-ISO 9409-1 interface
  • DIN 5480 standard interface
  • Couplings with a variety of locking methods.
