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.
- D Series: The D Series Single Convolution models feature a standard design suitable for general-purpose applications. They consist of a single air bellow made from high-quality rubber, reinforced with synthetic cords for durability.
- F Series: The F Series Single Convolution models are constructed with a reinforced design using premium materials, including high-strength rubber compounds and additional layers of synthetic reinforcement. This enhances their ability to withstand higher pressures and mechanical stresses.
- D Series: Designed for moderate load capacities, typically ranging from 0.5 to 5 tons, making them suitable for standard industrial machinery and equipment.
- F Series: Engineered to handle higher load capacities, generally ranging from 1 to 10 tons, ideal for heavier machinery and more demanding applications.
- D Series: Operates effectively at standard air pressures, up to 6 bar (87 psi), sufficient for applications with moderate force 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: Available with effective diameters ranging from 80 mm to 300 mm, suitable for applications needing less force and compact installation spaces.
- F Series: Features larger effective diameters, from 100 mm to 400 mm, resulting in a greater effective area for force transmission.
- D Series: Provides a standard maximum stroke length of up to 150 mm, adequate for applications with limited vertical displacement.
- F Series: Offers extended maximum stroke lengths, up to 200 mm, accommodating greater vertical movement and flexibility.
- D Series: Has natural frequencies typically ranging from 3.0 to 5.0 Hz, suitable for standard vibration isolation requirements.
- F Series: Exhibits lower natural frequencies, from 2.0 to 3.5 Hz, enhancing vibration isolation capabilities for sensitive equipment.
- D Series: Made with high-quality rubber compounds and standard reinforcement layers, providing reliable performance in typical industrial environments.
- F Series: Utilizes premium rubber compounds with additional synthetic cord layers (e.g., nylon or aramid fibers), offering superior tensile strength and resistance to wear.
- D Series: Equipped with standard steel bead plates or crimped end closures suitable for moderate stress levels.
- F Series: Features heavy-duty end closures and bead plates, often treated with anti-corrosive coatings for enhanced longevity in harsh conditions.
- D Series: Suitable for standard temperature ranges, typically from -20°C to +60°C (-4°F to +140°F).
- F Series: Capable of operating in a wider temperature range, from -40°C to +70°C (-40°F to +158°F), due to specialized rubber formulations.
- D Series: Allows for standard angular misalignments up to 6 degrees, appropriate for less demanding setups.
- F Series: Designed to accommodate greater angular misalignments up to 10 degrees, thanks 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, often exceeding 25 bar (362 psi), ensuring safety under extreme conditions.
- D Series: Suitable for static or low-frequency dynamic applications with less intense operational cycles.
- F Series: Better suited for higher-frequency dynamic applications involving rapid load changes due to enhanced damping characteristics.
- D Series: Provides reliable fatigue life for applications with normal operating cycles, generally up to 300,000 cycles.
- F Series: Offers an extended fatigue life exceeding 500,000 cycles, making them ideal for continuous operation.
