ROSTA抗振支座选择器为抗振装置提供指示性选择：

Vibration isolation: Estimation only, not inclusive of damping effect. Please contact ROSTA for specific data or damping coefficient.
Not inclusive of cold flow effect (rubber settling).
The load is assumed to be distributed equally.
Feasibility of subcritial applications can be consulted with ROSTA.
Vibration amplitude and remaining compression to be accounted for to asure efficient mounting performance.
ROSTA mountings can have dissimilar capacities in X, Y, Z directions.
*High-amplitude, high-frequency vibrations may overheat the ROSTA element. For frequencies higher than 50 Hz, the amplitude cannot exceed compression equivalent to 0.5° rotation angle of ROSTA element.
More anti-vibration mounts are available.

ABI型

ABI型ROSTA振荡支座为免维护弹性摇杆，用于支撑或悬挂各种设计和驱动系统的自由振荡振动设备。它们在输送方向上辅助提供驱动力，并确保机器振荡部分的良好线性导向。振荡支座的受电弓结构允许在负载下产生较大的弹簧挠度，从而产生较低的固有频率（低至约2.2 Hz），因此对支撑结构具有极高的隔振效率。ROSTA振荡支座较高的横向稳定性可防止筛壳在通过共振频率时的摆动，这是螺旋弹簧装置的典型特征。

所有ABI型振荡支座均采用不锈钢制作（AISI 304），且可与蓝色AB型振荡支座互换！

ABI-HD型

The oscillating mounting type ABI-HD is the "Heavy Duty" version in the AB mount family of the ROSTA screen suspensions. For example the ABI-HD type 50-2 offers 40 % more load capacity compared to the standard version AB 50-2 (14′000 instead of 10′000 N) by a slightly higher natural frequency (f = approx. 2,7 Hz instead of 2,3 Hz).

The ABI-HD screen mount is the ideal suspension for mining- and aggregate screen working under variable charging capacities and are less sensitive on possibly occurring overload situations. Furthermore, due to the high load capacity, these mountings are also predestined for screens submitted to impact loading situations (e.g. charged by front-end loaders).
All ABI-HD oscillating mountings are in stainless steel (AISI 304) and interchangeable with the blue AB-HD oscillating mountings!

ESL型

ESL型ROSTA抗振支座可吸收中低频振动，设计用于承受压缩、拉伸和剪切载荷以及复合型载荷。它们可以安装在任何需要的位置，也适用于天花板和墙壁安装。

Due to the mechanically secured principle of the anti-vibration mounts type ESL no tearing off is possible. These elements are maintenance-free, insensitive to water and dirt and suitable for temperatures from -40°C to +80°C. The housing and core of the elements up to size 45 are made of light alloy with steel brackets. The housing of size 50 is made of GGG 40. All elements are paint-finished.
