When comparing TEVEMA’s D Series and F Series Single Convolution Air Springs, several technical specifications differentiate the two, making each series optimal for specific industrial applications. Below is a detailed technical comparison focusing on the single convolution models.
- F Series: Designed to handle higher maximum loads, typically ranging from 2 to 20 tons. This makes them suitable for supporting heavier machinery and equipment in demanding industrial environments.
- D Series: Suited for moderate loads, with maximum load capacities generally ranging from 0.5 to 10 tons, ideal for standard industrial applications.
- F Series: Capable of operating at higher nominal pressures, usually up to 8 bar (116 psi). The higher pressure capacity allows for greater force output and load support.
- D Series: Operates effectively at standard pressures, typically up to 6 bar (87 psi), sufficient for applications with moderate force requirements.
- F Series: Features larger effective diameters (e.g., 150 mm to 700 mm), resulting in a greater effective area for force transmission.
- D Series: Comes with smaller effective diameters (e.g., 80 mm to 500 mm), suitable for applications needing less force.
- F Series: Offers extended maximum stroke lengths, potentially up to 300 mm, accommodating greater vertical movement and flexibility.
- D Series: Provides shorter maximum stroke lengths, up to 200 mm, adequate for applications with limited vertical displacement.
- F Series: Exhibits lower natural frequencies (e.g., 1.5 to 3.0 Hz), enhancing vibration isolation capabilities, especially for heavy loads and sensitive equipment.
- D Series: Has higher natural frequencies (e.g., 3.0 to 5.0 Hz), suitable for applications where less vibration isolation is acceptable.
- 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: Made with standard rubber compounds and fewer reinforcement layers, offering reliable performance for typical industrial 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: Utilizes standard end closures and bead rings suitable for moderate stress levels and less aggressive environments.
- 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: Suitable for standard temperature ranges, typically from -30°C to +60°C (-22°F to +140°F).
- F Series: Designed to accommodate greater angular misalignments up to 12 degrees and lateral misalignments due to their flexible construction.
- D Series: Allows for standard angular misalignments up to 8 degrees, appropriate for less demanding setups.
- F Series: Higher burst pressure ratings, often exceeding 30 bar (435 psi), ensuring safety and reliability under extreme conditions.
- D Series: Standard burst pressure ratings around 20 bar (290 psi), adequate for typical operating conditions.
- F Series: Better suited for high-frequency dynamic applications involving rapid load changes due to superior damping characteristics and material resilience.
- D Series: Suitable for static or low-frequency dynamic applications with less intense operational cycles.
- F Series: Offers an extended fatigue life exceeding 1 million cycles, thanks to enhanced materials and robust construction, making them ideal for continuous operation.
- D Series: Provides reliable fatigue life for applications with normal operating cycles, generally up to 500,000 cycles.
