Vibration-damping and vibration-isolating rubber laminated structural materials 'URB' and 'NRB'
Data sheets are being presented. We can accommodate changes in color and elasticity. We offer a lineup of polyurethane and natural rubber with excellent damping properties.
Our company provides laminated structures made of rubber materials and steel plates that respond to horizontal loads and contribute to vibration reduction, seismic isolation, vibration control, and vibration suppression. We offer a lineup of 'URB (Urethane Rubber Bearings)' with excellent damping properties and the ability to be colored, as well as 'NRB (Natural Rubber Bearings)' made from natural rubber. These can be designed to meet specific needs regarding the rubber's elasticity (hardness), shape, and dimensions. If you are considering vibration countermeasures in mechanical or structural design, please feel free to consult us. 【Features】 - Urethane products exhibit low stiffness and high damping across a wide amplitude range. Special shapes other than cylinders and prisms can also be produced using casting methods. - Natural rubber products are suitable as spring elements, with numerous applications in machinery, construction, and civil engineering. - The hardness (elasticity) of the rubber can be widely adjusted. *For more details, please refer to the materials available for download in the <Catalog>.
