History 1997

Rexroth technology is used in the world's largest shovel excavator. Launch of the "Solitaire", the world's largest pipe-laying vessel, with Rexroth hydraulic systems on board.

History 1999

Rexroth hydraulic components are used in the "mega mole" tunneling machine for the Elbe tunnel.

History 2001

Merger of Mannesmann Rexroth AG and Bosch Automation Technology to form Bosch Rexroth AG.

History 2005

Launch of IndraDrive Mi, the first motor-integrated servo controller, in which the motor and controller are combined in a single unit.

History 2009

A hydraulic pump combined with a controlled electric motor will only generate as much hydraulic power as is needed for a given task or machine cycle. Sytronix variable-speed pump drives reduce energy consumption by up to 80 percent.

History 2010

Variable displacement pumps are very energy efficient, as they only supply energy in line with demand. For the first time, the A1VO axial piston variable displacement pump exploits these advantages for small tractors and auxiliary drives in working machines.

History 2011

Compliance with legal noise emission standards without encapsulation: the SILENCE PLUS external gear pump operates 15 db(A) quieter than comparable pumps.

History 2011

The IndraMotion MLC control system automates complete machines and systems. It combines motion, logic and robotics with a unique openness towards high-level language programming.

History 2011

Start of production of planetary screw drives for use in medium and heavy machine manufacturing.

History 2012

The Hydraulic Traction Assistant HTA ensures greater traction for nearly all types of commercial vehicles. As an on-demand all-wheel drive system, HTA is approximately 400 kg lighter than mechanical solutions.

History 2012

The electrohydraulic self-sufficient axis consists of a pump drive, a hydraulic cylinder and its own fluid circuit. A power and communication cable is sufficient as a connection.

History 2012

As a system partner for large-scale projects, Rexroth implements unique worldwide automation solutions again and again, such as for the first adaptive shell structure in the world or the powerful hydraulics for use in the "La Yesca" dam in Mexico.

History 2013

HVT gearboxes combine the advantages of a hydrostatic and a mechanical drive. They enable a sensitive, precise positioning of the vehicle, while the stepless hydro-mechanical gearboxes lower the fuel consumption in the mechanical drive by up to 20 percent.

History 2013

Open Core Engineering supplements PLC programming with a bridge to the IT automation. The technology interface, which won the HERMES AWARD in 2013, opened up new ways of networking with information technology and Industry 4.0.

History 2013

IndraDrive ML increases the power range of electric drives by up to four megawatts. Due to intelligent energy management functions, the drives reduce power consumption during the movement of heavy loads.

History 2013

With the patented entry zone, the runner blocks of the RSHP roller rail systems smoothly take up loads and improve accuracy in high precision manufacturing.

History 2014

The Electrohydraulic Hitch Control ensures even and gentle soil cultivation. With EHC-8, Rexroth provides these advantages for the first time in tractors of up to 80 PS sold in fast-developing countries.

History 2014

Leading operator of industry 4.0: On the networked multi-product line in the Homburg/Saar Bosch Rexroth plant, employees are installing 200 different variants of highly-efficient hydraulic valves in nine intelligent stations.

History 2014

New benchmark for force density: Despite being only half as big as the previous model, the Hägglunds CBM hydraulic direct drive produces 50 percent more torque.

History 2014

Control cabinet-free drive technology: With IndraDrive Mi, machine manufacturers reduce the wiring cost by up to 90 percent, as the servo motor, controller and all networked components can be placed directly on the machine - thus saving the space required for a control cabinet.

History 2014

The IndraControl XM control platform offers more intelligence for Industry 4.0 applications and links it with extremely fast processing of process signals.

History 2014

It is as precise as a glass scale, yet it remains unaffected by impacts, vibrations or electromagnetic fields: the incremental measuring system, IMS-I, is fully integrated into the ball and roller rail systems.

History 2015

The fuel-saving hydraulic HSS stop-start system independently switches the diesel motors off and starts them again using the previously saved hydraulic energy.

History 2015

Intelligent, networkable hydraulics: The ABPAC hydraulic unit independently monitors all operating data and components and reports wear before it leads to a failure.

History 2015

Operators achieve increased equipment availability through the ODiN service package. Rexroth registers all operating data and evaluates it with specially developed software to reliably detect wear before it causes a system standstill.

History 2015

The MS2N servo motor offers a significantly increased power density and serves in connection with control units as a sensor and data source in networked production. The data delivers important information for future maintenance and increased productivity.

History 2015
