Anti-vibration rubber
・On both sides of the Kura Pad, an array of four protrusions with different diameters and heights is provided so that the pressure receiving area increases as the load increases.
・A low natural frequency can be obtained over a wide range of loads, from light-load precision machinery to heavy-load applications, and excellent anti-vibration effects can be obtained.
・Deflection changes depending on the load
Easy to flex under light load and hard to flex under heavy load.
・The level of the machine does not change
Even if there is a difference in the magnitude of the supporting load, the level of the machine hardly changes.
・Machine does not walk
It has good lateral stability and does not walk even when the machine is on the floor.
・Easy to install and move
Easy to install and move the machine. It can be cut to an appropriate size on site, and is effective simply by laying it under the machine.
・Great soundproofing effect
It is effective in preventing noise, resonance, and blocking high-frequency vibrations.
・Economic
Economical installation compared to using anti-vibration rubber.
*Please leave a gap between the nut and the bush to prevent vibration from propagating to the foundation bolt.
