Polyurethane Shock Absorber Block for Hydraulic Breakers

When it comes to reducing noise, vibration, and wear in hydraulic breaker operations, polyurethane shock absorber blocks offer an effective and durable solution. These essential components, typically installed between the hammer body and the chisel or other key parts, help extend the equipment’s service life and improve overall performance.

What Is a Polyurethane Shock Absorber Block?

A polyurethane shock absorber block is a precision-molded part made from high-performance polyurethane elastomer. It is designed to absorb and cushion the intense impact forces generated during the operation of a hydraulic breaker (also known as a rock breaker or demolition hammer). Thanks to polyurethane’s superior elasticity and resilience, the shock absorber block plays a vital role in reducing equipment stress and operator fatigue.

Application in Hydraulic Breakers

In hydraulic breakers, the shock absorber block is typically installed as an intermediary buffer to reduce the transmission of vibration from the piston strike to other components. By softening the shock and dampening noise, it protects both the tool and the excavator arm from excessive wear and tear. This results in:

Reduced maintenance frequency

Extended equipment lifespan

Improved operator comfort

Lower downtime and operating costs

Advantages of Polyurethane Material

Compared to rubber or metal alternatives, polyurethane offers several key advantages:

High wear resistance – stands up to repeated impact and friction

Excellent shock absorption – reduces vibration transmission

Weather and oil resistance – performs well in harsh outdoor environments

Longer service life – cost-effective over time

Our polyurethane shock absorber blocks are customizable in terms of size, hardness (Shore A), and color, ensuring a perfect fit for various breaker models and working conditions.
