Servo couplings - Shaft couplings
Metal Bellows Coupling
Metal bellows couplings are backlash-free, flexible all-metal couplings with high torsional rigidity and minimal mass moments of inertia. Various clamping connections and different metal bellows shapes are available for a wide range of applications.
Properties:
- Backlash free
- High torsional stiffness
- Low restoring forces
- Offset compensating
Elastomer couplings - Claw couplings
Elastomer couplings are plug-in, backlash-free, flexible shaft couplings for low to medium torques. A plastic
star with high Shore hardness serves as a connecting and compensating element. The elastic star can compensate for minor shaft misalignments, is electrically insulating and has good good vibration damping behavior.
Properties:
- Backlash free
- Vibration damping
- pluggable
- electrically insulating
- Offset compensating

With the clutch finder from JAKOB Antriebstechnik, you can find the right clutch from our product range with just a few questions and settings.
Miniature clutches
Miniature clutches are servocompensating couplings, which are used in particular for tachos, NC axes, stepper motors, potentiometers, rotary encoders, angle encoders or servo
drives. They are available as torsionally rigid metal bellows couplings, vibration-
damped elastomer couplings or highly compensating cross-slide couplings.
Properties:
- compact
- Powerful
- Offset compensating
- Torsionally rigid and backlash-free miniature metal bellows couplings
- Vibration-damping and backlash-free miniature elastomer couplings
- Highly compensating miniature cross slide clutches
Distance couplings - Cardan shafts
Distance coupling, also known as intermediate axles or cardan shafts, are servo
couplings for large center distances without complex intermediate bearings. The common design feature of distance coupling is a variable-length intermediate tube that can be optimally adapted to the customer-specific application.
Properties:
- Variable overall length
- No additional intermediate storage necessary
- Offset compensating
- Backlash free
- Torsionally rigid metal bellows spacer clutches
- Vibration-damping elastomer distance coupling

Shaft couplings - The origin
Servo couplings (or shaft couplings) are a sub-segment of our product range that also marks the origin of JAKOB Antriebstechnik. Couplings of this product type transmit torque backlash-free and at the correct angle from input to output shaft and, depending on the design, also function as compensating couplings that can compensate for considerable shaft misalignment. In addition, our servo couplings are characterized by the highest possible torsional rigidity and minimal mass moments of inertia. The high balancing quality enables excellent operating behavior even at high speeds.
The servo couplings product range consists of four core areas: Metal bellows couplings, elastomer couplings (claw couplings), miniature couplings and distance coupling.
JAKOB Antriebstechnik originally made a name for itself with metal bellows couplings and can be considered the original. Over forty years ago, Ludwig Jakob developed the cone crimping process for connecting metal bellows and hub, which is now the industry standard. Metal bellows couplings offer maximum torsional rigidity and at the same time are wear-free in applications up to 350°C. The ability to compensate for shaft misalignments depends on the design and shape of the metal bellows acting as a compensating element. Various friction-locked clamping and conical hub connections are available for connection to the input and output shaft, but a customer-specific flange connection is also possible in many cases.
Elastomer couplings, or claw couplings, offer particularly convenient and easy handling during installation thanks to their pluggability. At the same time, the elastomer spiders used have a vibration-damping and electrically insulating effect, although their material properties only allow them to be used up to a maximum of 120°C, sometimes with reduced operating parameters. They are therefore a cost-effective alternative for applications with low to medium torques and are also able to compensate for minor shaft misalignments.
JAKOB Antriebstechnik offers miniature couplings for the smallest drives in a wide variety of designs, which, however, largely correspond to their larger relatives, the metal bellows and elastomer couplings. In addition to the two well-known variants, JAKOB Antriebstechnik offers miniature couplings with cross-slide parts as a compensating element, which can compensate for particularly large radial shaft misalignments.
The range of servo couplings is rounded off by distance couplings and cardan shafts, which can transmit torques over distances of up to six meters without the need for intermediate supports. Couplings from this range are available both as elastomer and metal bellows couplings. For particularly demanding applications with high speeds, we offer the variable-length intermediate tube made of CFRP. Manufactured in a splitted hub design, distance couplings from JAKOB Antriebstechnik can generally be installed by a single person.
