2. Characteristics of the Ringfeder Industrial Buffers:
– The Industrical Buffers is manufactured by Ringfeder/Germany.
– The function of Ringfeder Industrial Buffers, combined with their high load-bearing capacity and low weight, is highly efficient. Since they are made entirely of the materials they are constructed from, they require minimal size and weight. Therefore, the decisive factor here is the performance of the spring.
– The shock absorption capability of Industrial Buffers is standard at 66%, ensuring that energy is absorbed and completely neutralized. This can be adjusted with different types of lubricants.
– Overload safety at the blocked position is typically designed to “stop” Industrial Buffers, ensuring that stress limits are not exceeded and the equipment remains undamaged.
– Independent of loading speed, the force-stroke diagram of Industrial Buffers applies to all operating conditions. Unlike other shock-absorbing systems, Industrial Buffers provide both spring action and shock absorption even when the load is applied extremely slowly or rapidly.
– With hydraulic damping and springs made of composite materials, the force transmission curve will be affected by temperature fluctuations and inherent temperature increases. However, the characteristic curve of Industrial Buffers remains unaffected by these factors and can be used within a temperature range from -40°C to +80°C without significant changes, as the inherent temperature rise of the spring due to damping effects has been taken into account.
– Like the standard Ringfeder Industrial Buffers product line, we can provide special solutions based on specific applications.
– Industrial Buffers allow for optimal use of available installation space due to their nesting structure, using parallel or series spring arrangements.
