ROSTA’s feeder and free-vibrating screen’s elements are an ideal alternative to popular suspensions such as springs or rubber cylinders. They provide many years of failure-free operation, even for 3-shift cycles.

Main advantages of ROSTA elements:

• corrosion resistance
• high vibration isolation to the support frame
• completely linear oscillations
• short and smooth stopping
• impact and overload resistant
• provide stable support
• do not require side movement protection
• smooth transition through the resonance frequency of the system
• completely maintenance-free suspension
• easy mounting and replacement
• quiet work
