Both the outer ring and inner ring of the CSD type feature an integrated (one-piece) structure. Its outer diameter is the same as that of the CSG type, while its strength is higher than CSG type components. It is mainly used in the output section of CSD series reducers.
The CSD type harmonic drive bearing is a specially designed component developed to meet the specific requirements of harmonic drive systems. With its integrated design for Compact Series Drive (CSD) harmonic reducers, it provides the essential support for their unique motion control capabilities.
Main Features:
·Compact Design: The load-bearing structure of the CSD type is designed to minimize size while maintaining maximum load capacity. This compact design is critical for space-constrained applications such as robotics and automation.
·High Torque Transmission: The bearing system in CSD high-speed planetary reducers is optimized for high torque transmission, ensuring efficient power transfer and precise motion control.
·Reduced Backlash: In harmonic drive systems, gear tooth clearance (backlash) directly affects motion accuracy. The CSD type bearing is designed to minimize backlash, thereby improving positioning accuracy.
·Precision Manufacturing: These bearings are manufactured using high-precision processes to meet extremely strict accuracy standards and performance requirements. This ensures the reliability and long service life of harmonic drive systems.
Applications:
·Robotics
·Aerospace
·Medical equipment
·Automation and other high-precision motion control systems
