CEF POLYMERES is a major supplier of a diverse range of engineered rubber and bonded metal/ rubber products for the vehicule, mining, rail, construc on and industrial markets. Our products are exported worldwide.technologies and skills, breadth and depth of exper se, advanced rubber development exper se, and a variety of manufacturing processes. Elements of an Isola on System In discussing vibra on protec on, there are three basic elements to be considered: 1.An element which creates or transmits vibra onal energy. 2.An element which must be protected, or "isolated" from that energy. 3.A third...

DECREASED MAINTENANCE COSTS When vibra ng equipment is rigidly bolted to the floor, internal stresses may be amplified. We reduce these stresses and help prevent misalignment of machine frames and undue wear on bearings or related parts. Con nued maintenance labor costs are reduced and replacement of worn parts is reduced. IMPROVED PRODUCTION EFFICIENCY Produc on machinery operates more efficiently when isolated from vibra on. Higher machine output and quality are possible at higher opera ng speeds without disrup on from neighboring equipment. CHOICE & AVAILABILITY OF SOLUTION With CEF mounts, you...

Technical informa on Frequency and Damping A spring suspended from a ceiling, if stretched downward and released, would con nuously vibrate up and down at a fixed number of oscilla ons per unit me if the spring could vibrate freely and were a perfectly resilient material. This number of oscilla ons per unit me is known as natural frequency. In a prac cal sense, however, no real material is perfectly resilient. All isolators exhibit some degree of non -resilience known as damping. If the spring suspended from the ceiling were cri cally damped, it would not oscillate aGer being stretched and released,...
