About us

OTT-JAKOB Spanntechnik GmbH is one of the world’s leading manufacturers of clamping systems for the machine tool industry. With manual and automatic clamping systems, rotary unions, unclamping units and electronic assistance and control systems, the company covers the entire range of tool clamping technology applications.

Over the past 50 years, the owner-run company headquartered in the German Allgäu region has become a strong development partner to leading spindle and machine manufacturers all over the world. Since the development of the first automatic steep taper power drawbar in 1974, the provider of complete tool clamping units has set numerous standards on the market: the development of the DIN 2080 (OTT-Rille) in 1978, the launch of a single-passage rotary union with permanently closed sealing surfaces in 1997 and the expansion of the product range with manual clamping systems in 2010 – to only name a few milestones.

OTT-JAKOB's company headquarters, nestled in the Allgäu countryside.

We stand for the highest precision. Quality assurance is our top priority.

Our clamping systems are manufactured in a modern production hall.

OTT-JAKOB produces high-quality components for tool clamping technology. Customised complete clamping systems made of high quality components.

pull-in force monitoring: Power-Check famliy

The Power-Check 2 from OTT-JAKOB detects changes in the pull-in force before disruptions occur in the production process. By using the measuring device regularly, you avoid rejects and also benefit from consistently precise machining results.

OTT-JAKOB offers three diferent types of measuring devices:

  • Power-Check 2: The Power-Check 2 from OTT-JAKOB detects changes in the pull-in force before disruptions occur in the production process. By using the measuring device regularly, you avoid rejects and also benefit from consistently precise machining results.

  • Power-Check Magazine: Equipped with a gripper groove and long-term battery, the Power-Check Magazine is simply integrated into the tool magazine. Thanks to a self-activation mechanism, the measurement starts automatically during the exchanging process. The data is transmitted wirelessly to OTT-JAKOB receiver units.

  • Power-Check Micro: The new HSK EZ15, E16 and E20 interfaces require a particularly precise device for measuring the pull-in force. That is why we have developed the compact Power-Check Micro specfically for these small interfaces. The measured values are sent wirelessly to a computer via the USB radio stick supplied.

Our Power-Check family comprises three different measuring devices and a wide range of different adapters.

The base unit of the Power-Check 2 can be combined with different adapters for all common interfaces (in this case HSK63).

The Power-Check Micro is the smallest of our pull-in force measuring devices.

The Power-Check Micro is specially designed for the HSK EZ15, E16 and E20 interfaces.

The Power-Check Micro is supplied in a case together with the USB radio stick.

Our Power-Check Magazine remains permanently in the tool magazine. The measured values are transmitted wirelessly to your computer.

external leakage sensor

With external leakage monitoring, the calorimetric sensor is positioned in a measuring device that is installed in the leakage drain of the rotary union.

If the programmable and predetermined flow rate limit is exceeded inside the tube, a signal is emitted which appears directly on the measuring device or which can be sent to the machine control unit. Two basic variants are available: for water-based and oil-based coolants.

With modern machine tools, the availability of information about the clamping condition of the tool is absolutely essential in order to comply

with safety guidelines. The rotary union 2KA-ME from OTT-JAKOB is a simple and compact all-in-one solution that combines the company‘

s proven dual-passage rotary union technology with an innovative distance measurement system.

With our dual-passage rotary unions, you can supply hydraulic oil to release the clamping system through one passage whilst feeding another medium through the second passage. It is attached to the spindle shaft.

complete clamping systems

As a manufacturer of complete tool clamping systems, the development of tailored system solutions lies at the heart of OTT-JAKOB’s expertise. The decades of experience in automatic clamping technology are reflected in a range of perfectly coordinated products. OTT-JAKOB clamping systems are modular and make it possible to combine standard components as well as special elements manufactured to our customers´ specifications.

The product range includes the well-established interfaces SK, HSK and PSC (Coromant CAPTOTM), as well as the high performance interface KM4XTM. The range is rounded off by an extensive offer of rotary unions and unclamping units.
