PLM Isolators - Rubber air springs

PLM Air spring elements

PLM air spring elements offer low-frequency vibration and shock isolation for measuring stations, coordinate measuring machines, fans, air compressors, motor and generator units, high-speed presses and more.

The PLM air spring series comprises low-frequency vibration and shock isolators which reduce undesirable vibrations while simultaneously levelling the supported devices.

When used as a vibration damper, the internal air chamber already guarantees a signicifant isolating effect from 5Hz upwards. In an optimal loaded condition, the natural frequency is 3.0 Hz. PLM air spring elemets also isolate in a pressure-free state.

Properties: 

• Low natural frequency of 3 Hz,
• Easy level control via integrated valve,
• Height regulation control on request,
• Ratio of horizontal to vertical natural frequency 1:1. 

Areas of application: 

• Measuring tables,
• Test benches,
• High-speed presses,
• Production plants.
