Common Applications of Rubber Shock Absorbers

Rubber shock absorbers are common components in mechanical equipment, primarily made from rubber. They offer excellent vibration-dampening performance, are durable (with a low failure rate), and effectively extend the service life of the equipment they support. They also protect the vibration-dampening assembly, facilitate easier installation, and provide good electrical insulation. Let's look at some common applications for rubber shock absorbers.

When selecting a shock absorber, it is important to first understand its characteristics and then choose based on the operating environment. Rubber shock absorbers feature customizable shapes and adjustable stiffness; they offer higher damping ratios than metal springs and provide resistance to shear, tension, and compression forces, all while being easy to install. Their drawbacks include a relatively high natural frequency, a shorter service life, and environmental limitations-typically requiring an operating temperature range of -30°C to 70°C. In environments with chemical exposure, shock absorbers made from specific, chemically resistant rubber materials must be selected.

The most common materials used to manufacture rubber shock absorbers are natural rubber, neoprene, and nitrile rubber. However, the market is also flooded with shock absorbers made from reclaimed rubber; these feel hard and lack elasticity, exhibit non-linear load-compression characteristics, have rough surfaces, offer poor vibration dampening, and age quickly. Exercise caution and avoid purchasing these types of shock absorbers.

For stamping equipment-such as punch presses, die-cutting machines, and hydraulic presses-the impact frequency should be kept away from the rubber shock absorber's natural frequency. Because rubber shock absorbers provide vibration dampening in all directions, they are widely used in the automotive, aerospace, and marine industries.

The above summarizes common applications for rubber shock absorbers. Understanding these details allows you to select and use them correctly based on your specific needs, thereby reducing the risk of failure caused by improper usage.
