How do Non-Suspension Shock Absorbers perform in hot and cold environments?

The performance of non-suspension shock absorbers in high and low temperature environments is closely related to their material properties, structural design, and application scenarios. To ensure that non-suspension shock absorbers can work stably under extreme temperature conditions, manufacturers usually select materials suitable for various temperature environments and design shock absorbers that can withstand temperature changes. The following is an analysis of the performance of non-suspension shock absorbers in high and low temperature environments:

In high temperature environments, the performance of non-suspension shock absorbers is mainly affected by the following aspects
High temperature may cause thermal expansion or deformation of shock absorber materials, which in turn affects their structure and performance. Especially in metal materials, excessively high temperatures can cause the strength of the metal to decrease, which may cause the shock absorber to deform or fail. For polymer materials, high temperatures can cause them to soften, age, or melt. To address these issues, non-suspension shock absorbers usually use materials with high thermal stability, such as high-temperature resistant alloys, special polymers, or ceramic materials.
In some non-suspension shock absorbers, oil (such as damping oil) is a key component in the shock absorption process. Under high temperature conditions, the oil may volatilize, oxidize, or change in viscosity, which may affect the efficiency and effectiveness of the shock absorber. When the viscosity of the oil decreases, the damping effect of the shock absorber may be weakened, thereby affecting the vibration absorption effect. To solve this problem, many shock absorbers use specially designed high-temperature oil or other high-temperature working fluids to ensure their stable performance.
Under high temperature conditions, the sealing materials of the shock absorber may be affected, resulting in seal failure. High temperatures can cause the sealing materials to age or soften, causing oil leakage or contaminants to enter the shock absorber, affecting its performance. To improve the sealing performance, manufacturers usually choose high-temperature resistant sealing materials, such as fluororubber or special high-temperature sealing rings.

Long-term exposure to high temperature environments may accelerate the aging process of shock absorber materials. Metal materials may be affected by thermal stress, resulting in fatigue and cracking; while polymer materials may harden and become brittle. In order to increase the service life of non-suspension shock absorbers, materials that resist heat aging are usually selected and special heat treatment processes are performed.
In low temperature environments, non-suspension shock absorbers also face a series of challenges, which are mainly reflected in the following aspects:
Low temperature environments may cause embrittlement of some materials, especially metals and some plastic materials. After the material becomes brittle, it may not be able to withstand external shock and vibration, causing the shock absorber to fail or be damaged. Therefore, shock absorbers used in low temperature environments usually use materials with good low temperature toughness, such as low temperature steel or engineering plastics suitable for low temperatures.
Low temperature increases the viscosity of the oil or liquid in the shock absorber, resulting in changes in damping performance. At extremely low temperatures, the liquid may become too viscous, and the response speed of the shock absorber may be affected, resulting in poor shock absorption. To solve this problem, oil with excellent low temperature performance or liquid designed to flow smoothly at low temperatures is usually used to ensure that the shock absorber can still work normally in cold environments.
Low temperature may cause the sealing material to shrink and harden, thereby affecting the sealing effect. Failure of the seal may cause oil leakage or the entry of external contaminants, which in turn affects the performance of the shock absorber. Therefore, when designing shock absorbers for use in low temperature environments, manufacturers will choose sealing materials that can remain soft and elastic at low temperatures, such as fluororubber or low temperature silicone rubber.
Temperature changes may cause the shock absorber material to expand or contract, which in turn affects the stability of its structure. In low temperature environments, the metal part of the shock absorber may shrink, and the sealing part or liquid may produce uneven pressure due to temperature changes, which will affect the overall effect of the shock absorber. To solve this problem, the design of the shock absorber usually takes temperature changes into consideration and takes appropriate compensation measures, such as using materials with better temperature stability or designing shock absorber structures with adaptive capabilities.
In order to ensure the performance of non-suspension shock absorbers under extreme temperature conditions, manufacturers usually take the following measures:
When designing shock absorbers, materials suitable for high and low temperature environments are selected to ensure their stability at different temperatures. For example, heat-resistant steel or special alloys are used at high temperatures, and low-temperature steel or specially treated plastic materials are used at low temperatures.
By improving the structural design of the shock absorber, such as adopting more efficient sealing solutions and oil control systems, the long-term stable operation of the shock absorber in high and low temperature environments can be ensured.
For high or low temperature environments, special oils that can operate stably at extreme temperatures are used to avoid oil viscosity changes or oxidation problems.
Strict temperature tests are performed on shock absorbers to ensure that they can work stably under various temperature conditions and achieve the expected shock absorption effect.

Non-suspension shock absorbers have different performances in high and low temperature environments, but through reasonable material selection, design optimization and testing certification, manufacturers can ensure that shock absorbers can still maintain excellent performance under extreme temperature conditions. In practical applications, choosing suitable shock absorbers for different working environments and performing regular maintenance and inspections are the key to ensuring their long-term stable operation.
