3.5OSM - Open Spring Mounts

OSM open spring mounts are designed to provide efficient isolation from critical vibrations and efficiently protect structures from transferring vibrations.

 

The top spring cup has a leveling nut for precise adjustments in height. Anti-vibration rubber cups reduce the transfer of vibrations and noise. Springs are color coded for easy identification.

Available in four sizes:

OSM-500: Ruber cups are 5" in diameter, and the springs are designed for 3" deflection.

OSM-350: Ruber cups are 3.50" in diameter, and the springs are designed for 1" and 2" deflections.

OSM-250: Ruber cups are 2.50" in diameter, and the springs are designed for 1" and 2" deflections.

OSM-150: Ruber cups are 1.50" in diameter, and the springs are designed for 1/2" deflection.

 

Recommended for:


HVAC equipment, fan air circulation systems, compressors, pumps, chillers, AC units, cooling towers, inertia bases, etc.

Open spring mounts are not designed to accommodate angular misalignments, and must not be used for tensile or shear loading.

Features:
All springs at rated loads have 50% additional travel to solid load.
Leveling nut for easy height adjustment.
Safety Factor - springs will accommodate 50% extra load from rated load to solid load.
Spring cup base has an attachement hole for anchoring.
Elastomer spring cups provide better vibration isolation, load distribution, and noise reduction.
Recommended load range: from 50% of rated load to rated load.
Springs are color coded and easily replaceable.
Springs have a minimum ratio of 0.8 for the diameter divided by the deflected spring height (*).
