Supersoft Erethane Busings
- Low creep rate compared to other polymers (rubber, neoprene, silicone etc.) - Superior damping coefficient over a verywide temperature range. - Can absorb shock efficiently for millions of cycles.- Temperature Ranges: -15°C to 98°C.- Bushings can isolate vibration and absorb shock.This material is a soft visco-elastic polymer. Visco-elastic means that a material exhibits properties of both liquids (viscous solutions) and solids (elastic materials).It has the properties of a thermoset, polyether-based, polyurethane material. The material combines shock absorbtion, good memory, vibration isolation and vibration damping characteristics. In addition it is a very effective acoustic damper and absorber. While many materials exhibit one of these characteristics, it combines all of them in a stable material with a long fatigue life. Using two bushings together or a bushing and washer(s), you can create a floating bolt that isolates the unit from any metal-to-metal contact.Different shores allow for different spring rates. Load ratings assume a 10% - 20% deflection of the material. This deflection is achieved by a combination of system weight and torquing of the connecting bolts.Do not over torque the bolts as this defeats the intended vibration isolation and shortens bushing life. Use a high-quality (thread deforming) lock nut or doubled jam nuts to prevent vibration from loosening the bolt.Unlike other products, bushings may be used in tension connections.
