Gewinde Ziegler AG's decades of experience in thread grinding led to the foundation of Gewinde Satelliten Antriebe AG (GSA AG) in 1982. Since then, GSA AG has been manufacturing high-precision planetary roller screws (RGT). With know-how accumulated over generations, GSA AG has become one of the leading international manufacturers of planetary roller screws with the ISO 9001:2015 and ISO 14001:2015 certificates.
Planetary roller screws are a particularly precise and robust form of linear drive. Their construction design produces significantly higher load capacities and rigidity compared to other linear drives, such as ball screws (KGT). This is a direct result of the so-called threaded planets used in the design. The threaded planets serve as rolling elements between the threaded spindle and the threaded nut. Another great advantage of planetary roller screws is the wide range of possible leads they offer. The multi-start thread profile of the planetary roller screws allows total spindle leads of 0.5 mm to 50 mm.
Specifications
- High limiting speed and high travel speed
- High axial load capacity
- High axial rigidity
- High positioning accuracy and very precise repeatability
Designs
GSA AG's product range includes four types of planetary roller screws which differ in their operation modes and properties. The screws are manufactured in standard dimensions, but also according to customer-specific designs. All components are manufactured and assembled in-house at GSA AG / Gewinde Ziegler AG.
