Rubber Buffers vs. Metal Springs: Which One Provides Better Shock Absorption?

Rubber Buffers or Metal Springs: What Has Better Impact Absorption


With equipment as large and heavy-duty as this, shock absorption is a must. Heavy equipment in mining, transportation and construction are commonly exposed to difficult terrain and heavy loads resulting in high levels of impact and vibration. In these cases, the decision of whether to use rubber buffers or metal springs for damping becomes key. Background Headquartered in Shenzhen, KFT has extensive experience in industrial manufacturing solutions, equipment using rubber and silicone for vibration damping on larger machinery. 

Comparison of Rubber Buffers vs Metal Springs

Rubber bumpers and metal springs are typical shock absorbers for use in heavy machinery. It will be understood that the rubber buffers may be of general known type, being formed from an elastomeric material such as (for example) silicone or rubber which is capable of flexing and storing energy e. g. when struck and/or vibrated. Metal springs, on the other hand are generally formed from steel or other suitable metal alloys which impart stiffness and resilience to absorb energy and cushion shock. Rubber buffers as well as metal springs perform the function of energy absorption, but there are significant differences in both behaviour and characteristics. 

Rubber Buffers vs. Metal Springs

Rubber mounts and rubber cushions have a lot of the following advantages as compared to metal springs. Rubber has flexible and deformable characteristic, having the absorb ing energy higher internal dampening vibration when operating heavy equipment will be safer. Rubber buffers are also rust-resistant, being suitable for harsh conditions. Epdm sheet rubber offer increased load bearing capacity and more durability than rubber buffers but can be subject to fatigue and wear degradation. 

The Difference between Rubber Buffers and Metal Springs in Machines

Rubber buffers or metal springs, which one you should choose? Equipment with rubber buffer can benefit from less wear and tear, greater stabilisation as well as improved comfort for the operator, thanks to excellent shock absorption in rubber. By contrast, equipment based on rubber foam pad could be more appropriate for high-load contexts where stiffness and robustness are key, while compromising on maintenance and replacement frequencies. 

Comparison Between Rubber Buffers and Metallic Springs

The choice of whether to absorb impact in such heavy equipment by means of rubber buffers or rubber foam sheet ultimately conditioned on the requirements and operational situations for the industrial machine. Rubber buffers achieve excellent shock attenuation, vibration isolation and resistance to corrosion; whereas metal springs provide the higher load capabilities and durability. Based on the knowledge and resources from Shenzhen Kingfund Technology Co., Ltd. (KFT), Industrial makers are now able to confidently decide about adding rubber or silicone material specifically for shock absorption in heavy systems, ultimately increasing reliability and production safety in a wide range of industrial scenarios.
