Service life increased by 80 percent

Same construction size, nearly doubled life time: Bosch Rexroth has once again considerably increased the dynamic load capacities of the ball screw assemblies thanks to optimized production pro

Rexroth ball screw assemblies: Available worldwide and with short delivery times

Bosch Rexroth has achieved an up to 80 percent increase in the service life of its ball screw assemblies thanks to continuously improved production processes. Design engineers are thus able to use smaller sizes for the same power requirements. At the same time, Bosch Rexroth has shortened the delivery time for its customized ball screw assemblies through the digitalization of engineering and ordering processes, as well as optimized logistics processes. In Europe, for example, some of these assemblies are delivered from the factory within 24 hours.

As a leading manufacturer of linear motion technology, Bosch Rexroth has relied on the cold shaping rolling process for screw manufacturing for decades. During this time the company has continuously increased its manufacturing expertise and improved its processes. At the same time, the manufacturer has also further developed the processes for producing nuts. These improvements in both screw and nut production have increased the dynamic load capacity of the ball screw assemblies in the accuracy classes T3 and T5 by 20 percent. The dynamic load capacity is a decisive parameter for the size selection and the service life of ball screw assemblies.

The improved dynamic load capacity increases the nominal life of the ball screw assemblies from Rexroth by up to 80 percent. Comprehensive stress and life cycle tests in various usage scenarios validate these values. The increased load capacity leads directly to an increase in power density. Design engineers can therefore use a smaller size in many cases to deliver the same required amount of power. This reduces system costs, saves installation space and lowers the weight.

Short delivery times thanks to modern logistics and lean processes

Screws and nuts are basic components that Bosch Rexroth manufactures centrally at its factory in Schweinfurt/Volkach. The factory supplies regional warehouses in all major markets. Bosch Rexroth thus offers consistently high quality with short delivery times worldwide. At the Customizing Centers in Europe, Asia and America, the screws are cut to length and the ends are machined according to the customer's specific requirements.

Rexroth has now collected the configurable linear motion systems and components ordered most often into the GoTo Focused Delivery Program. In Europe, for instance, the company is able to deliver ball screw assemblies from the GoTo Focused Delivery Program within 3 to 5 working days, sometimes even within 24 hours.

Digitalized configuration and ordering

Rexroth has digitalized the entire engineering and ordering process. Using the Linear Motion Designer (LMD) calculation tool, design engineers can determine the appropriate ball screw assemblies. In the next step, they can change to the configuration tool and immediately see whether the selected component is part of the GoTo Focused Delivery Program. Following individual configuration, registered users can place all components into their shopping cart in the Rexroth eShop. But before the binding order is placed, the system shows the delivery date and the price.

Economical, precise, safe, and energy efficient: drive and control technology from Bosch Rexroth moves machines and systems of any size. The company bundles global application experience in the market segments of Mobile Applications, Machinery Applications and Engineering, and Factory Automation to develop innovative components as well as tailored system solutions and services. Bosch Rexroth offers its customers hydraulics, electric drives and controls, gear technology, and linear motion and assembly technology all from one source. With locations in over 80 countries, more than 31.100 associates generated sales revenue of approximately 5.4 billion euros in 2015.

Software of the future: Freed from …

…the restraints of hardware – the software of the future. In the factory of the future, machine modules and processing stations will be regularly reorganized, flexibly take on new tasks and retrieve the appropriate software function. This change has already begun: Machine manufacturers are already able to install identical control functions on various device platforms without any extra effort. Here is an overview of concepts for today and tomorrow:

Rexroth takes users on a digital journey of Linear Motion Technology

Instead of the previously strictly separate work steps in the dimensioning, configuration, start-up, actual use and diagnosis of Linear Motion Systems, Bosch Rexroth shows with a trade fair exhibit as a study the advantages of a continuous digital journey through the entire life cycle. Here, software tools and all individual pieces of information accompany the components and systems of Linear Motion Technology. At the Automatica 2018 trade fair, Bosch Rexroth is using a multi-axis system with its own intelligence as an example to present the entire range of production-ready and close-to-production digital solutions with which design engineers and users can react to changing conditions more quickly and flexibly than ever before.
