Note: For accurate identification of seal placement, refer to the model-specific exploded view or service manual during installation.
Key Features
- Material Strength: Constructed from heat-resistant polyurethane (PU), NBR, and PTFE compounds for excellent elasticity and wear resistance.
- Seal Precision: CNC-machined to ensure proper compression and sealing contact, reducing internal leakage and improving breaker response.
- Wide Compatibility: Available for multiple Doosan breaker models, including HB-series and DXB-series.
- Long Service Life: Designed for heavy-duty applications with prolonged cycle durations and minimized maintenance.
Installation Methods
Method 1: Standard Mounting Pin Assembly
- Use the mounting pin to align seals during installation.
- Apply lubricant to reduce friction and avoid seal twisting.
Method 2: Professional Tool-Assisted Installation
- Use a ballast tool, locating cone sleeve, and auxiliary pressure plate to insert seals without damage.
- This method is recommended for larger or tight-fit models.
