Made in: Japan
Manufacturer: SANWA TEKKI
Model : Mechanical Snubbers

The STC Mechanical Snubbers are the result of meticulous engineering, serving a dual-purpose that is both innovative and essential. They excel in their ability to effectively prevent unwanted displacements within piping systems when subjected to the forces of seismic or dynamic events. Simultaneously, they provide the flexibility needed for unimpeded thermal expansion and contraction.

This groundbreaking design represents a seamless fusion of cutting-edge technology. It incorporates a rotary inertia mass, ingeniously engineered to naturally resist sudden movements. Furthermore, it employs a ball screw assembly, renowned for its proficiency in converting linear motion into precise rotary motion.

The importance of this design reaches far beyond its exceptional engineering prowess. Its international recognition and patent protection in diverse nations, such as Japan, the United States, Canada, and the United Kingdom, underline its global significance.

Leveraging a specially developed Japanese grease, STC Mechanical Snubbers have been engineered to operate without the need for maintenance while maintaining an impermeable seal, rendering them exceptionally well-suited for deployment in environments characterized by heightened radiation levels. This exceptional quality sets them apart from Hydraulic Snubbers and underscores their superiority in such challenging conditions.

The design principle of our Mechanical Snubber utilizes an inertia mass which generates a different magnitude of resistance force against the input load in proportion to its acceleration level.
This equation, represented as Mα=F (where M denotes Mass, α signifies acceleration, and F represents the generated force), illustrates a fundamental principle. When subjected to low input acceleration, it leads to the generation of a resistance force at a negligible level, enabling unrestricted movement of piping. Conversely, when exposed to high levels of acceleration, it produces a substantial resistance force, effectively restraining and controlling the vibration of the piping system in its entirety.
