Bosch Rexroth increases service life of ball screw assemblies by 80%

Bosch Rexroth ball screw assemblies from Tectra Automation now have up to 80% more service life thanks to continuously improved production processes by the manufacturer. This means that design engineers are now able to use smaller sizes for the same power requirements. At the same time, Bosch Rexroth has shortened the delivery time for its customised ball screw assemblies through the digitalisation of engineering as well as optimised logistics processes.

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, improved its processes and 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%. 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%. 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 to deliver the same required amount of power in many cases. This reduces system costs, saves installation space and lowers the weight.

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, enabling the manufacturer to offer consistently high quality with short delivery times worldwide.
