Describe
SD rubber cushion
The rubber vibration isolating pad is successfully developed according to the rubber dynamic characteristics. It has a circular hollow hollow, corrugated shape, cylindrical multi-point shape, etc. It has oil resistance, corrosion resistance and aging resistance. Generally, it is mainly subjected to shearing force, has low natural frequency, simple structure and convenient use. It is widely used in vibration isolation and noise reduction of various vibration machinery equipment, such as machine tools, fans, water pumps, air compressors, refrigerators, diesel engines. The positive vibration isolation of the machine and the negative vibration isolation of all kinds of precision instrument instruments and optical instruments have obvious vibration isolation effects. Technical conditions 
Working temperature: -15 ° C ~ 70 ° C
Damping ratio: 0.086
Natural frequency: 4.7 ~ 17.2Hz
 
[Product Certification]: ISO 9001-2008
[Scope of application]: construction, water supply and drainage, light and heavy industry, refrigeration, sanitation, plumbing, fire protection, electricity
 
Features
The SD type rubber vibration isolation pad is made of high-quality nitrile rubber as the main raw material, and is mainly subjected to shearing force. This product has the following characteristics:
 
1: Low natural frequency, large damping and good oil resistance;
 
2: Wide range of applications and various ways of use. Due to the reasonable shape and structure design, it can be cut according to different load requirements, and can also be used in single or multi-layer according to different vibration isolation and noise reduction requirements;
 
3: The negative vibration isolation effect on the instrumentation is good, and the high-frequency vibration isolation effect of the impact machine such as punching machine and forging bed is more obvious.
 
4: This product is widely used in the active vibration isolation of pumps, fans, compressors, chillers, punching machines, forging machines, textile machinery and other mechanical equipment and vibration protection of all kinds of precision instruments.
