Suspension springs in accordance with DIN 28134 – a highly effective solution for mechanical tensile loads
Tension springs conforming to DIN 28134 are among the unassuming yet essential components in industrial equipment and plant engineering. At first glance, they appear simple and unassuming: a metal spring body with a defined spring characteristic curve, designed for tensile loads. Despite their unassuming appearance, however, they perform a demanding task, as they decouple, cushion, and stabilize heavy components under dynamic loads. As such, they are primarily used in process engineering systems where vibrations, thermal expansion, and fluctuating inertial forces occur. In these applications, suspension springs conforming to DIN 28134 are a critical factor for operational safety and the service life of the machinery. We’ll show you what matters in the manufacture of suspension springs according to DIN 28134 and what production options are available to you. In addition to standard suspension springs, we can also produce custom dimensions, which are available with or without heat treatment.
What are suspension springs?
DIN 28134 defines suspension springs that are relevant for use in equipment, vessels, and piping systems. The standard aims to ensure reproducible, safe, and predictable spring performance that can withstand the daily stresses of routine operation. In particular, it defines geometric dimensions, common materials, spring core values, permissible load limits, and other test criteria. This ensures that suspension springs can be used internationally under comparable conditions without unpredictable deviations in their behavior. Unlike conventional tension springs, suspension springs in accordance with DIN 28134 are specifically designed for continuous use under high static loads. The standard also takes into account typical load scenarios that regularly occur in industrial plants—such as those caused by vibrations, pressure surges, or fluctuating fill levels in containers.

Materials and Surfaces of Suspension Springs According to DIN 28134
Suspension springs manufactured according to DIN 28134 are typically made of high-strength spring steel, which combines high elasticity with sufficient fatigue strength. However, depending on the operating environment, other materials may also be considered, supplemented by customized surface treatments. For example, galvanizing, heat treatments, painting, or special coatings are possible to provide optimal protection against corrosion, particularly when the suspension springs are used in a humid, chemically aggressive, or outdoor working environment. Especially in sensitive areas, such as the chemical industry or in plant engineering with high hygiene requirements, special materials or stainless steel variants may also be required; while these are more cost-intensive, they offer significantly higher resistance to corrosion. If you need such a custom-made product, you’ve come to the right place—we have a wide range of all common materials available from stock and can therefore produce custom-made products for you quickly and cost-effectively.
The Advantages of Suspension Springs at a Glance
Suspension springs are a key component in industrial machinery and plant engineering and must be able to withstand high loads. They offer a wide range of advantages:
Predictable spring behavior: Thanks to standardization, spring characteristics, permissible loads, and operating ranges are clearly defined. This makes design planning easier and reduces the risk of miscalculations.
High operational reliability: Suspension springs in accordance with DIN 28134 are designed for continuous static loading with additional dynamic stress. This ensures a high level of operational reliability.
Vibration and shock damping: Suspension springs decouple components from vibrations, pressure surges, and load cycles, resulting in less material fatigue and reduced susceptibility to damage in adjacent components.
Long service life: When suspension springs are used within their intended operating range, they remain elastic and resistant to fatigue. This results in reduced wear and low maintenance requirements.
Easy integration: Suspension springs in accordance with DIN 28134 can be integrated into existing suspension systems without complex modifications.
Correct installation is essential for optimal performance of the suspension spring. It must be loaded precisely in the direction of tension to avoid transverse forces. An uneven position or improper suspension of the spring leads to uneven stress and significantly shortens its service life. To distribute loads evenly, suspension springs in accordance with DIN 28134 are often installed in pairs or groups in practice. However, this requires careful coordination of the spring rates, as even small deviations can cause one suspension spring to be overloaded while others remain largely inactive.
