Port Size G1/2 Dunlop SP1540 Air Spring Suspension Firestone W01-R58-4060

The Introduction of Air Suspension

The 1B12×1T air shock suspension is a reliable, high-performance air spring widely used in industrial and automotive applications. It is designed to provide effective vibration isolation, load handling, and shock absorption with its durable, double convoluted structure. Constructed with high-quality rubber, the 1B12×1T air bag features an airtight inner layer and an oil-resistant outer layer, offering excellent wear resistance and long-lasting performance. Commonly found in vehicles like trucks, trailers, and specialized machinery, the SP1540 pneumatic air rubber bellow enhances stability and reduces vibration, ensuring smoother operations. Its superior elasticity and load capacity make it well-suited for heavy-duty environments. Additionally, its compatibility with similar models makes it a practical replacement option in various systems.

Key Roles in Application

1. Vibration Damping:

Minimizes vibrations generated during high-speed cutting operations, ensuring machining accuracy and surface finish quality.

Reduces resonance effects between the machine structure and external disturbances (e.g., floor vibrations).

2. Load Compensation:

Automatically adjusts internal pressure to compensate for variable tooling loads, maintaining consistent machine bed alignment.

Supports dynamic weight shifts during multi-axis movements (e.g., spindle head repositioning).

3. Advantages of SP1540 in This Application:

• High Load Capacity: Designed to handle static and dynamic loads up to 4,000 N, suitable for medium-to-heavy CNC machines.
• Compact Design: Fits into space-constrained machine bases without interfering with operational components.
• Precision Pressure Control: Integrated regulators enable real-time stiffness adjustments for optimal process stability.
• Durability: Corrosion-resistant materials and reinforced bellows ensure reliability in coolant-exposed environments.
