Schaeffler, a renowned company in the field of motion technology, has launched an innovative series of bearings that has the potential to transform the machine tool industry. The presentation took place during the EMO Hannover fair, where the company showcased its PTB series of angular contact ball bearings, specifically designed for automated tools. This new offering is positioned as a cost-effective solution for both original equipment manufacturers and the modernization of existing tools.
With decades of experience in developing precision bearings and drive systems for machinery, Schaeffler is known for its wide range of components that include linear guidance systems and linear motors, which are ideal for main shafts. Additionally, these bearings are also used in rotary tables and milling heads. According to Christian Straub, Manager of Development in Industrial Automation, bearings for rotary axes are optimized to require low maintenance while providing stiffness suited to current market demands.
The PTB series features advanced technology with hybrid bearings for spindles, designed to prevent “false Brinelling,” a type of damage that can affect raceways in applications with short movements. These hybrid bearings use ceramic rolling elements, significantly enhancing both their performance and durability.
Schaeffler has also introduced the KLLT series of ball recirculation systems, which are particularly suitable for handling systems and peripheral devices in production machines. This design, which features an X-shaped arrangement, allows for a more precise adaptation to substructures with shape errors, minimizing restraining forces.
Furthermore, the company has made a strong commitment to automation, highlighting its series of bearings for rotary axes, YRTA, which are designed to facilitate pallet changes. Included in this series is the YRTAG model, which features an innovative gear system integrated into the inner ring, optimizing the construction space and speeding up the assembly process.
Additionally, Schaeffler has emphasized the importance of lubricants to maximize bearing lifespan, presenting Arcanol lubricant as a key component for the performance of rotating and linear systems. During EMO, attendees have the chance to learn more about the rigorous quality testing of lubricants and the various engineering services the company offers.
With these innovations, Schaeffler reaffirms its commitment to advanced technology and its dedication to ongoing development in the automation and machinery sector.
