Introduction
ROSTA specializes in providing durable, maintenance-free elastic suspensions for screening machines and shaker conveyors. Their products include rocker-arms, drive-heads, resilient rod-heads, and spring accumulators, all designed to be energy-efficient, quiet, and capable of handling high dynamic spring rates.

Product Specifications

• Elastic Suspensions: These are suitable for various screening machines and shaker conveyors, offering high isolation and resistance to corrosion.
• Universal Joint Suspensions: Specifically designed for gyratory sifters, these provide durable articulations and can support forces up to 40,000 N per mount.
• Oscillating Mounts: Available in multiple types (AB, AB-HD, AB-D, ABI, HS, AK, AV), each with different load capacities and natural frequencies, tailored for specific applications such as impact loading and high production peaks.

Selection Tables
Selection tables are provided to help choose the appropriate mounts for free oscillating systems, gyratory sifters, and guided systems. These tables include details on load capacities, natural frequencies, and specific applications for each mount type.

Technology and Design
ROSTA's technology supports free oscillating systems using exciters, unbalanced motors, or shafts. The design ensures optimal oscillation amplitude and conveying speed, with mounts effectively dissipating residual force peaks. Recommendations are provided for mounting configurations to optimize performance in circular and linear motion screens.

Technical Diagrams and Formulas
Diagrams illustrate vibration isolation, deflection curves, and cold flow behaviors. Formulas are included for calculating oscillating machine factors, centrifugal force, and loading per corner, aiding in precise system design and evaluation.

Conclusion
ROSTA's mounts and suspensions are engineered to enhance the performance and longevity of screening machines and conveyors, offering solutions that are maintenance-free, noiseless, and resistant to overload and corrosion.
