High-damping HB30G shock absorber pad set, OEM interchangeable upper and lower damper cushion for Furukawa HB30G hydraulic breaker, anti-fatigue vibration buffer pad, factory wholesale excavator breaker spare parts.
Advanced Product Technology
Strict Raw Material Screening: All raw rubber materials undergo professional tensile, hardness and aging tests. Recycled inferior rubber is completely rejected to guarantee overall product stability.
Precision Internal Mixing Technology: Automatic banbury mixing ensures uniform molecular fusion of PU and natural rubber, achieving balanced elasticity and compression resistance across the entire cushion.
Micron-Level Precision Molding: CNC machined molds strictly controlled within ±0.02mm tolerance, fully restoring OEM groove and mounting accuracy.
Secondary Post-Curing Treatment: Eliminates internal molding stress, improves rebound resilience and avoids early deformation under alternating loads.
100% Pre-Shipment Inspection: Finished products go through deburring, dimensional sorting and compression fatigue sampling test to eliminate defective goods.
Working Principle
The upper shock absorber pad bears the axial downward impact from the breaker cylinder, buffering instantaneous striking pressure during rock breaking.
The lower damper cushion disperses upward reaction vibration generated by stone crushing, offsetting hammer rebound force.
The high-damping composite material converts vibration kinetic energy into thermal energy through continuous compression and rebound, realizing efficient shock absorption.
It isolates rigid metal-to-metal contact between the hammer cylinder and outer shell, preventing shell cracking and abnormal operating noise.
It blocks excessive vibration transmission to the excavator boom, protecting hydraulic pipelines and structural parts from fatigue damage.
FAQ
Q1: Does this product include both upper and lower cushions?
A1: Yes, one full set contains one upper pad and one lower pad for complete replacement.
Q2: What is the main material of this HB30G damper pad?
A2: Adopts high-damping PU + natural rubber composite material for balanced elasticity and shock absorption.
Q3: Do you support sample orders and bulk wholesale?
A3: Sample orders are acceptable, and bulk purchases enjoy tiered preferential pricing and fast delivery.
