SD type rubber shock absorber
SD type rubber isolation pad is made of oil-resistant rubber vulcanized. It has properties such as oil resistance, corrosion resistance and aging resistance.
Product Description
SD type rubber isolation pad is made of oil-resistant rubber vulcanized. It has properties such as oil resistance, corrosion resistance and aging resistance. It is a universal seismic isolation component successfully developed based on the dynamic characteristics of rubber. It has the characteristics of simple structure and easy installation and use. It is widely used in seismic isolation and noise reduction of various types of mechanical equipment. It has a remarkable effect on isolating high-frequency vibration and impact vibration of machinery and reducing solid sound transmission of house structures.
SD type rubber isolation pads have three rubber hardnesses: 40°, 60°, and 80°. The basic block size is 85mm*85mm. It can be cut and combined arbitrarily according to the different load requirements of mechanical equipment. The isolation pads can also be stacked in series in multiple layers. After use, the load is still the single-layer load, but the natural frequency can be reduced and the isolation effect is better. The multi-layer combination is separated by steel plates and bonded with glue.
Working temperature: -5~50°C
Damping ratio: 0.098
Natural frequency range: 5~18HZ
