Polyurethane Damper For Hydraulic Breaker

PEPSEN is a China manufacturer and supplier of polyurethane dampers for hydraulic breakers with consistent quality and stable material performance. Our dampers are made from high-grade cast polyurethane, offering excellent shock absorption, wear resistance, and fatigue resistance. Compared with rubber alternatives, polyurethane dampers provide longer service life and more stable parameters under continuous impact. We support custom design, competitive pricing, clear technical parameters, and responsive after-sales service for global customers.

Our OEM-capable factory caters to mining, construction, quarrying, and road construction industries. We produce full sets of hydraulic breaker accessories including upper cushions, elastic pads and side plates to meet one-stop procurement needs of global equipment factories and maintenance firms.

Case Studies: How Polyurethane Damper For Hydraulic Breaker Solved Client Challenges

Case 1 — Roadwork Contractor

• Problem: Rapid upper cushion wear on frequent pavement breaking jobs.
• Solution: Replaced with 80A oil‑resistant cast polyurethane upper cushion.
• Result: Cushion life increased, fewer changeovers, lower annual replacement spend.

Case 2 — Quarry Operator (Factory Maintenance)

• Problem: Side plates eroded by abrasive stone and debris.
• Solution: Thicker cast urethane side plates with textured surface.
• Result: Reduced wear frequency and improved breaker service ranking with maintenance team.

Case 3 — OEM Breaker Manufacturer

• Problem: Early fatigue on elastic pads causing noise and operator vibration complaints.
• Solution: adjust hardness of elastic pad and bonded shock absorber assembly. See more about how to choose hardness of polyurethane.
• Result: Noise and vibration dropped, customer satisfaction has risen significantly.

Selection Guide of Polyurethane Damper For Hydraulic Breaker

- Confirm your hydraulic breaker model (e.g., SB series, HB series) for precise fitting.

- Evaluate working conditions: Choose 70–80A for low-impact tasks, 85–95A for mining.

- Check environmental factors: Opt for stainless steel cores in corrosive settings.

- Request samples: Test damping performance and fit before bulk ordering.

- Verify product certifications: Prioritize ISO 9001-certified products for quality assurance.

- Consult technical support: Get recommendations for matching upper cushions and side plates.
