Introduction
The document provides detailed information about the RESTON®SA shock absorbers, designed by mageba for seismic protection. These devices are crucial for preserving structures by dissipating energy during seismic events, thus reducing structural impact.

Characteristics & Dimensions
RESTON®SA shock absorbers are velocity-dependent devices comprising a piston, piston rod, and cylinder pipe. They allow free movement under normal conditions but control displacement and dissipate energy during sudden movements like earthquakes. The resistance force is determined by the flow of a viscous fluid through the piston.

Properties
The shock absorbers provide over 30% additional damping, reducing design loads on structures. They are often used with seismic isolators like LASTO®LRB and RESTON®PENDULUM to further mitigate forces.

Main Dimensions
The document includes a table listing the dimensions of various types of RESTON®SA devices, detailing axial force and maximum displacement capabilities.

Materials & Construction
Key materials include S355 steel for outer parts, 42CrMo4 steel for piston rods, and cast steel for hydraulic valves. The viscous fluid used is protected against aging and temperature variations, ensuring consistent performance.

Corrosion & Temperature Resistance
Standard corrosion protection is provided according to EN ISO 12944. Devices are designed to operate between -10°C and +50°C, with options for extended ranges. They can withstand temperatures above 200°C temporarily.

Service Life & Maintenance
With high-quality materials, the devices have a service life of 50 years with minimal maintenance. Visual inspections are recommended every 5 years.

Quality & Support
mageba's quality system is ISO 9001:2008 certified, with factories certified for welding and steel construction standards. Full-scale testing is available, and installation supervision is recommended to ensure proper setup.

Customer Support
mageba offers comprehensive support, including product selection advice and detailed documentation available on their website.

Conclusion
RESTON®SA shock absorbers significantly enhance structural safety and longevity, tailored to client needs for both new constructions and retrofits.
