Vibration isolation, vibration elimination, and vibration control for small structures and small equipment! Rubber can be colored in various colors, and the hardness of the rubber can be changed!
We would like to introduce our "Urethane Rubber Bearings (URB)." By using a laminated structure that alternates layers of urethane rubber and steel plates, we can achieve low horizontal stiffness while supporting structures and equipment, making it possible to use them as seismic isolation and vibration isolation components. Since we employ a casting method for manufacturing, we can accommodate not only cylindrical and rectangular shapes but also special shapes. 【Features】 ■ High linearity in horizontal load-displacement characteristics ■ Ability to achieve low stiffness and high damping over a wide amplitude range ■ High damping performance in the horizontal direction ■ Can also be used as vibration control and cushioning components ■ Can be customized to meet specific shape and size requirements *For more details, please refer to the PDF document or feel free to contact us.
