An increased by up to 80% life Ball Screws Bosch Rexroth has achieved by continuously improving production processes. With the same power requirements, designers can thus use an alternative smaller sizes. At the same time manufacturers shortened by digitization of engineering and ordering processes and optimized logistics processes, the delivery times for customized ball screws.
This is based on the cold-forming rolling process for spindle production. At the same time, the manufacturer has also further developed the production processes in nut production. These improvements in both spindle and nut production increase the dynamic load ratings of ball screws in the T3 and T5 accuracy classes by 20%. The dynamic load rating is a crucial parameter for the design of the size and the service life of ball screws.
Comprehensive load and life tests under a wide range of application scenarios validate the increase in service life. The increase in load capacity also leads directly to an increase in power density. For example, in Europe the ball screws are delivered within three to five working days, sometimes even within 24 hours. The entire engineering and ordering process has been digitized throughout. Designers use the Linear Motion Designer (LMD) calculation tool to determine their suitable ball screw drives.
