When evaluating TEVEMA’s D Series and F Series Triple Convolution Air Springs, it’s crucial to understand the technical distinctions that make each series suitable for specific industrial applications. Below is a detailed technical comparison, focusing on the specifications of the D Series in contrast to the F Series.
- D Series: Designed for standard load capacities, typically ranging from 1 to 20 tons, making them ideal for general industrial machinery and equipment with moderate load requirements.
- F Series: Engineered to handle higher maximum loads, usually ranging from 5 to 50 tons, suitable for heavy-duty machinery and demanding industrial environments.
- D Series: Operates effectively at standard pressures, typically up to 6 bar (87 psi), sufficient for applications with moderate force and load support requirements.
- F Series: Capable of operating at higher nominal pressures, up to 8 bar (116 psi), allowing for greater force output and load support.
- D Series: Comes with effective diameters ranging from 100 mm to 500 mm, appropriate for applications needing moderate force.
- F Series: Features larger effective diameters of 200 mm to 700 mm, resulting in a greater effective area for force transmission.
- D Series: Provides maximum stroke lengths up to 300 mm, adequate for applications with limited vertical displacement.
- F Series: Offers extended maximum stroke lengths up to 450 mm, accommodating greater vertical movement and flexibility.
- D Series: Has natural frequencies ranging from 2.5 to 4.0 Hz, suitable for applications where standard vibration isolation is acceptable.
- F Series: Exhibits lower natural frequencies of 1.0 to 2.5 Hz, enhancing vibration isolation capabilities, especially for heavy loads and sensitive equipment.
- D Series: Made with standard rubber compounds and reinforcement layers, offering reliable performance for typical industrial environments.
- F Series: Constructed with high-strength rubber compounds reinforced with multiple layers of synthetic cords (e.g., nylon or aramid fibers), providing superior tensile strength and durability.
- D Series: Utilizes standard steel end closures and bead rings suitable for moderate stress levels and less aggressive environments.
- F Series: Equipped with heavy-duty steel bead rings and end closures, often treated with anti-corrosive coatings for enhanced longevity in harsh conditions.
- D Series: Suitable for standard temperature ranges from -30°C to +60°C (-22°F to +140°F).
- F Series: Capable of operating in a wider temperature range, from -50°C to +70°C (-58°F to +158°F), due to specialized rubber formulations.
- D Series: Allows for angular misalignments up to 8 degrees, appropriate for less demanding setups.
- F Series: Designed to accommodate greater angular misalignments up to 15 degrees and lateral misalignments due to their flexible construction.
- D Series: Standard burst pressure ratings around 20 bar (290 psi), adequate for typical operating conditions.
- F Series: Higher burst pressure ratings exceeding 30 bar (435 psi), ensuring safety and reliability under extreme conditions.
- D Series: Suitable for static or low-frequency dynamic applications with less intense operational cycles.
- F Series: Better suited for high-frequency dynamic applications involving rapid load changes due to superior damping characteristics and material resilience.
- D Series: Provides reliable fatigue life for applications with normal operating cycles, generally up to 500,000 cycles.
- F Series: Offers an extended fatigue life exceeding 1 million cycles, thanks to enhanced materials and robust construction.
