DESCRIPTION

The ARCH7 NavySeaMount (NSM) Series of mounts is a low frequency, high deflection mount designed for attenuation of high, energy shipboard shock inputs experienced with MIL-S-901D Heavyweight barge tests.  All mounts the series can attenuate the MIL-S-901D input to <15G's (vertical) and 9G's (athwartship) or better at listed static load ratings.  They also perform good vibration isolation of input frequencies >15Hz at rated loads.  Meets with approvals Mil-M-17185 standards for shipboard mounts.  Material choices allow for higher damping or low temperature performance if required.  Standard mount geometry throughout the series makes for easy mount and performance upgrade within the series as well as to other Shock Tech ARCH series size mounts when payload changes in mission or load.
