Drive Technology
From coupling manufacturer to innovation partner
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.
Overcoming Distance
Distance couplings, also known as cardan shafts, are servo couplings for large center distances without complex intermediate bearings. A common design feature of the distance coupling is a variable-length intermediate tube that can be optimally adapted to the customer-specific application.
Special Solutions
Custom-made products? Quite standard for us! We realize individual solutions from just one piece – please contact us for a personal consultation.
Elastomer Couplings
Elastomer couplings are plug-in, backlash-free, flexible shaft couplings for low to medium torques. A polyurethane spider with a 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 vibration damping properties.
Miniature Series
Miniature couplings are servo compensating couplings used primarily for tachometers, NC axes, stepper motors, potentiometers, rotary encoders, angle encoders, and servo drives.
They are available as torsionally rigid metal bellows couplings, vibration-damped elastomer couplings, or highly compensating cross-slide couplings.
Safety Couplings
As torque limiters and overload protection, safety couplings reliably prevent costly machine damage, repairs, and downtime. If the set torque is exceeded, the drive is mechanically disconnected.
Safety couplings are life insurance for your machine,
regardless of whether the malfunction was caused by incorrect operation, a programming error, material overload, or tool breakage.
Stainless Steel Versions
JAKOB Antriebstechnik offers many series in stainless steel versions. Resistance to chemicals, such as those used for cleaning in the food industry, is one of the material’s strengths.

Mechanical Clamping Elements
This clamping element group includes mechanical power clamping screws and power clamping nuts. They are designed for manual operation with simple handling, but for very high clamping forces. Various clamping mechanisms such as wedge systems or planetary gears are used for force amplification. used. The robust design, the self-locking function and a high overload capacity
guarantee maximum operational safety.
Force Measurement
The holding force of a clamping device during the machining of workpieces is a criterion of outstanding importance. It is decisive for the machining quality as well as for the safety of the machine operator, the workpiece and the machine tool.
Power Clamping Screw
– mechanical
– hydromechanical
JAKOB power clamping spindles for face plates and clamping plates on vertical, horizontal, center, face and roller lathes as well as grinding and special machines are designed for the highest demands and maximum workpiece weights with the greatest possible operational reliability. They are primarily suitable for installation in claw boxes or for direct mounting in face plates of turning, grinding and special-purpose machines.
Areas of Application
Clamping elements or clamping technology from JAKOB Antriebstechnik are used wherever workpieces or tools need to be secured securely and with high clamping forces. Thanks to sophisticated technology, all our clamping elements enable the application of enormous clamping forces, which can hardly or only with great effort be achieved with conventional clamping devices.
Hydromechanical Spring Clamping Systems
The hydromechanical spring clamping systems work in a mechanical-hydraulic interaction. The Clamping force is applied mechanically by a pre-tensioned disk spring assembly. The hydraulics are only
is required for the release stroke of the elements, whereby the tie rod or pressure bolt is released. With this system guarantees a high level of operational reliability, as the clamping force is always maintained at the full leakage losses, the full clamping force is always maintained.

This clamping element group includes mechanical power clamping screws, power clamping nuts and eccentric block clamps. They are designed for manual operation with simple handling, but for very high loads. clamping forces. Various clamping mechanisms such as wedge systems are used to increase the force, planetary gear or eccentric principle. The robust design, the self-locking function, and a high overload capacity guarantee maximum operational safety.
Vacuum Technology
Customer-oriented solutions for vacuum components
KF - Small Flanges
KF offer quick and easy installation using clamping rings. They are available in the DN range from 10-60 and in various materials (stainless steel/aluminium).
Valves for Vacuum Components
Valves are indispensable for shutting off or venting areas of a vacuum system and cover a wide vacuum range from rough vacuum to high vacuum. They are available in various designs such as angle valves, ball valves and venting valves and are made of high-quality materials such as stainless steel or brass.
ISO-K Flanges
ISO-K flanges are robust vacuum connections that are ideal for low, medium and high vacuum. They cover a wide DN range from 63-630 and are available in stainless steel or aluminium. The connection is made securely using clamp bolts.
Vacuum Pump Accessories
In vacuum technology, sealing valves together with gas locks are essential for the safe and clean evacuation of evacuated or gas-filled containers. Adsorption traps (zeolite traps) are indispensable for maintaining a clean vacuum, as they prevent the ingress of oil and water vapor and thus improve the performance and service life of vacuum pumps.
CF Flanges
CF flanges are the first choice for ultra-high vacuum applications. They are available in the DN range from 16-250. The connection is made via holes in the flange and screw sets that are used for fastening. A special feature here is the cutting edge on the flange and the use of metal gaskets.
Vacuum Services
Vacuum brazing using the brazing process, vacuum annealing, vacuum welding using the TIG process, helium leak test, glass bead blasting
Your Reliable Partner
In 1971, Ludwig Jakob founded the company JAKOB Maschinenteile in Kleinwallstadt as a sideline. Two years later, JAKOB produces resolver gearboxes and simple bellows couplings with keyway connections. One year later, the KSS coupling is developed and patented. With the KSS coupling, the principle of the friction-locked shaft-hub connection is applied for the first time. Even today, this principle has many imitators.
