CEF Elastoplots Rubber to metal antivibration
CEF POLYMERES is a prominent supplier of engineered rubber and bonded metal/rubber products for industries such as vehicle, mining, rail, construction, and industrial markets. Their products are globally recognized for advanced rubber development and diverse manufacturing processes.
Vibration protection involves three main components: a source of vibrational energy, an element to be protected, and an isolator that provides necessary vibration isolation. Isolators are crucial in reducing vibrational forces, preventing fatigue, and maintaining equipment efficiency.
CEF's vibration isolation solutions eliminate the need for costly foundations, reduce installation costs, and allow flexible equipment relocation, leading to decreased maintenance costs and improved production efficiency.
The document discusses the relationship between natural frequency, damping characteristics of isolators, and the forcing frequency of vibrational energy, providing a table illustrating isolation efficiency based on frequency ratios.
Details on various elastomers used in CEF products are provided, including hardness, tensile strength, elongation at break, resistance properties, operating temperature ranges, and mechanical properties.
CEF products include rubber-to-metal and steel isolators with specifications such as load capacity, deflection, and natural frequency, designed for specific applications with features like shock damping and noise isolation.
CEF products comply with several DIN and ISO standards for hardness, ozone resistance, traction, abrasion, creep, tear resistance, and maintenance storage.
CEF POLYMERES offers a comprehensive range of vibration isolation solutions that provide significant cost savings, improved equipment efficiency, and adherence to international standards, catering to a wide range of industrial applications.
The products are made from elastomer NR bonded to steel components, with varying hardness levels and natural frequencies, designed for fail-safe operation, shock damping, and resistance to oil, grease, and ozone.
Suitable for electric motors, medical equipment, fans, vibrators, and off-road vehicles, as well as construction-borne noise isolation and vibration isolation in various industrial settings.
Includes engine mounts (EM series), isolators with steel cup protection (EPC series), and high load dampers (J series), each with specific load capacities, deflection characteristics, and stiffness ratings.
Constructed using materials such as natural rubber (NR), chloroprene rubber (CR), and stainless steel, featuring integrated anti-rebound washers and designed for high longitudinal stability and differentiated stiffness across three axes.
Detailed ordering codes for each product type are provided, specifying dimensions, load capacities, and additional options such as leveling bolts and stainless steel variants.
Products offer high load capacity, axial and radial stiffness, and are customizable through machining and cutting, designed to provide effective vibration isolation and noise reduction in demanding environments.

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,...
