Shock can be defined as sudden changes of an object’s position, velocity and acceleration in a short period of time. Trelleborg’s shock mounts are designed to protect structures and equipment from destructive consequences of the shock wave. L and M Type shock mounts are vertical shock mounts that consist of an accelerator and a decelerator. These two components combined protect equipment by absorbing the energy from a shock wave. These mounts are a proven and cost-effective solution for the shock-proof suspension that also provides good vibration isolation, which is ideal for rotating equipment. Like other shock mounts from the Trelleborg portfolio, all L and M Type shock mounts are registered under NATO Stock Numbers (NSN). Trelleborg AVS-NL CAGE code is H0040.
