GN 356.2 Vibration Isolation Mounts Rubber, Hourglass Type, with Steel Components, with 1 Tapped Hole and 1 Threaded Stud

Standard Sheet GN 356.2 Print This Page Plastic Characteristics

Product description

Vibration isolation mounts GN 356.2 are suitable for the anti-vibration mounting of machine units such as compressors and pumps.

The hourglass shape absorbs side forces better compared with cylindrical vibration isolation mounts. The rubber also does not swell past the cross section d₁ under pressure loads.
