SEIT 1873 HISTORY 

SINCE 1873 

We combine traditional values like 

striving for perfection and precision 

with our commitment to innovation. 

New inventions and patents in all 

areas are the results. 

Innovative competence is an OTT-JAKOB 

tradition. 

Our company goes back to 1873 when 

Albert Ott founded the Mathematical- 

Mechanical Institute in Kempten 

1880 - World exhibition in Melbourne 

1897 - Exhibition in Chicago 

In 1974 we developed the power 

drawbar, which has been continuously 

improved to meet new application 

requirements. Today, 250,000 

machines worldwide are operating with 

the Ott power drawbar. 

On March 1, 1993 the company 

Ott-Spanntechnik merged with the 

Jakob Group. 

OTT-JAKOB Spanntechnik was born. 

1998 - We are celebrating 125 years of 

world-renowned capability in precision 

mechanics and tool clamping 

technology. 

A small company made its way to 

become the leading manufacturer of 

automatic tool clamping systems. 

IV

UNSER DENKEN PHILOSOPHY 

OUR THINKING 

In the past years OTT-JAKOB could further 

develop its leading position in tool clamping 

technology. 

Out of this position we entered the following 

commitments: 

1. Our highly motivated and trained employees 

produce customer oriented high-tech products 

in best quality. Know-how, team spirit and 

innovative power are the most important 

components for developing high-end clamping 

technology products for mechanical engineering 

2. All OTT-JAKOB product lines guarantee the 

optimum in system safety on the highest level 

of technological development. 

V

TRENDSERKENNEN 

RECOGNIZING 

A shorter Time-to-Market ratio secures 

your investments. But first one has to 

recognize the trends. 

Our Research & Development 

department cooperates with universities 

and research teams to develop customer 

oriented system solutions, which build 

trends for the future. 

Sensational test results: 

Our plant in Lengenwang tested several 

clamping units. 

The units were successfully clamped and 

released up to 9 million times with a 

speed of 0.13 seconds. 

VI

PERFEKTIONFERTIGEN 

FINISHING 

The employee and his 

knowledge are the 

center of attention 

Ott employees have years of 

experience and are innovative. 

They are familiar with complex 

speed calculations and 

limitations thereof for machine 

tool applications, necessary 

unclamp forces and other 

parameters. 

High-tech manufacturing 

machines and latest CAD 

software are employed with 

perfection. 

Years of experience, 

cooperation with leading 

machine and spindle manufacturers, 

internationally recognized 

competence and cooperation 

with universities in the 

development of standards 

maximise our performance. 

OTT-JAKOB maintains a close 

contact with engineers in 

research and development. 

This guarantees user-specific 

products, which work efficiently 

in practical applications. 

OTT-JAKOB – 

Success through perfection. 

VII

COMPLETESYSTEMS 

Standardization requires meeting the needs of the 

user. The Ott universal inside spindle contour is an 

important step towards modular tooling. 

It offers the manufacturer of machines and/or spindle 

units the ability to clamp different steep taper tools 

(taper/retention knob standard) simply by exchanging 

the gripper unit. 

We would like you to benefit from this advantage. 

Several variations of power drawbars with or without 

coolant, with hydraulic or pneumatic unclamp units 

can be built into the same spindles. 

Rotary unions and unclamp units are compatible and 

exchangeable. 

VIII 

We offer high performance at a fair price.

Due to recent innovations, we can 

now offer a complete program of 

HSK- and steep taper power 

drawbars. This makes OTT-JAKOB 

the only manufacturer who offers 

complete tool clamping systems. 

The impressive number of different modules 

with all necessary adaptations to customers 

and standards show the advantages of 

customer and user oriented product 

development. 

Take advantage of our professional design 

and engineering department to optimize your 

products and minimize your cost.

Minimalmengenschmierung: 

MINIMUM VOLUME LUBRICATION 

The latest technique of using minimum volumes of 

coolant for dry operations has become a focal point in 

the manufacturing industry. Ott-Jakob offers two 

variations for all HSK-clamping units: 

Internal 

External minimum volume lubrication 

Using external MMKS, the aerosol is produced in 

a special mixing device outside the spindle. 

Like coolant, the mixture is fed through a rotary 

union. OTT-JAKOB offers three variations of rotary 

unions to be used for external minimum volume 

lubrication for OTT-JAKOB HSK-clamping units: 

• Dual-passage rotary union 

(max. 10.000 RPM – mixed externally 

p max = 5 bar) 

• Single-passage rotary union GDR for 

OTT-JAKOB unclamp units (max. 16.000 

RPM – mixed externally p max = 5 bar) 

• Single-passage rotary union GD for 

OTT-JAKOB unclamp units (max. 36.000 

RPM – mixed externally p max = 5 bar) 

External 

Internal minimum volume lubrication 

Using internal MMKS, the air-lubrication mixture 

is produced inside the spindle. Air and minimum 

amounts of lubrication are fed separately into 

the spindle through the OTT-JAKOB HSK-clamping 

unit. 

They are mixed directly in front of the tool 

interface. Changing the mixture ratio allows 

for a quick adjustment of the aerosol doses. 

You can rely on us - in every situation! 

Both systems can be integrated as modules into 

existing as well as new HSK-clamping units. 

X

HSC - High Speed Cutting: 

Accelerated machining in the machine tool and mold 

making industry and in the cutting industry through 

High-Speed-Cutting (HSC) requires solutions for faster 

tool change. 

OTT-JAKOB's new clamping units, rotary unions and 

unclamp units meet these requirements. 

A shorter tool changing 

time represents a constant 

challenge, which 

even increased with 

HSC-manufacturing. 

Fast working automatic 

clamping systems are 

necessary which have 

to be more accurate, 

rigid and universal than 

conventional systems. 

OTT-JAKOB met these 

requirements by developing 

a complete new 

HSC-clamping unit. 

OTT-JAKOB has the necessary know-how

POWERCHECK 

All SK work holders from 

SK30 to SK60 

(DIN/ISO/ANSI) and all HSK 

work holders according to DIN 

69893 (HSK-A 32/B 40 to 

HSK-A 125/B 160) can be 

used. 

Conventional gages measure 

in accordance to the nominal 

component dimension. The 

manufacturing related tolerance 

range of the components 

could cause a false 

measuring result. The power 

check offers the possibility 

to take these tolerances into 

consideration during the 

measuring process! 

The critical guard 

The pull force gage "Power 

Check" minimizes the down 

times for your machines. 

It is a compact unit with power 

supply and adjustable tolerance 

range, which should not be 

missing in any production facility. 

The Power Check measures the 

pull force of your machines fast 

and reliable and prevents tool 

breaking and down times. 

Rely on OTT-JAKOB for the safety 

of your production!

KÜRZESTER SK-50 SPANNER 

SHORTEST SK-50 GRIPPER 

Highest Precision in smallest Space 

OTT-JAKOB has been designing and 

manufacturing Power Drawbars for 

the machine tool industry for over 

25 years. 

In the area of Steep Tapers, the 

traditional manufacturer from Bavaria 

has just developed a SK-50 Power 

Drawbar with a sensational short 

spindle of 298 mm lenght. 

Because of these new dimensions, 

new manufacturing methods became 

feasible of which machine tool 

designers in the past could only 

dream. This short spindle length of 

298 mm allows for optimum flexibility 

and space saving. 

5-axis heads, as well as nutating 

heads, can now be built more 

compact. 

As spindle speed of 6,000 RPM 

and a pull force of 15,000 N 

(3,370 Ibs) 

are features which can be 

advantageously utilized 

for extreme applications. 

Secure tool retention 

at extreme cutting 

conditions at any angle 

position can be realized. 

The coolant/air supply is 

possible through single or 

double passage rotary unions. 

The assembly of the OTT-JAKOB Power 

Drawbars can be done easily and 

quickly by average personnel. 

Thanks to the OTT-JAKOB universal 

contour.... 

.... the use of the most known standard 

tooling ist guaranteed: 

• DIN 61871 / 69872 

• ANSI B5.50 

• ISO 7388/1/2 Typ A 

• ISO 7388/1/2 Typ B

Intensifying mechanism and piston are built into an added-on cylinder outside the spindle shaft. 

The spring stack is built inside the spindle shaft. A signal ring enables position indication at the end 

of the spindle: 

XVI

I S Spindle integrated power drawbar 

The complete power drawbar is built into the spindle shaft. This form is used mainly for higher RPM: 

Function: 

Grippers with preloaded spring stacks or special springs and standard retention knobs pull the cutting 

tools into the spindle. A special intensifying mechanism amplifies the spring force of OTT-JAKOB steep 

taper power drawbars. The clamping system is locked at the same time. The pull force is a measure 

for the transmittable horsepower or torque of the motor. The compact design of the Ott-Jakob power 

drawbars offers high pull forces and system safety in the smallest installation spaces. 

I F Spindle integrated spring loaded power drawbar 

HSK-clamping units use only one form, similar to the IS-form for steep taper power drawbars: 

Function: 

During clamping of the hollow shaft taper (HSK), the clamping cone of the clamping unit presses the 

gripper segments radially to the outside. The spindle and the tool support the gripper segments. They 

pull the oversize hollow shaft taper into the spindle and clamp it against the axial face of the spindle. 

The patented design of the OTT-JAKOB HSK-clamping units amplifies the spring force of the intensifier. 

The friction between the taper and the face contact as well as the keyways transmit the torque. 

Spring stack or special springs generate the pull force.

Attention: 

Please note that high-speed units can only be designed after technical consultation and discussion of 

the intended application. Complex calculations are necessary to determine the RPM limit of the power

The world we are working in 

Lengenwang, the site of 

our plant, is situated in the 

middle of the beautiful 

Allgäu, where in the spring 

time the dandelions shine 

on the deep green 

meadows and the eyes 

are following the outlines 

of the Alps on the horizon. 

The landscape forms the 

people living there and it 

is also reflected in our 

company. 

The yellow of the dandelion 

meadows symbolizes 

human warmth and sunny 

friendliness in today's 

high-tech world.
