Which type of rail elastic clip has the longest service life?
The type of rail elastic clip with the longest service life depends on its diameter and material, with larger diameter clips generally lasting longer, such as the E clip with a diameter of 20mm, which has a fatigue life of 5 million cycles. The SKL clip is also a common type and its specific fatigue life is not detailed, but its lifespan is also determined by its material and manufacturing quality.
- Diameter is a key factor: For E clips, a 20mm diameter clip has a higher fatigue life (5 million cycles) compared to an 18mm diameter clip (3 million cycles).

- Proper manufacturing matters: A high-quality production process, including strict dimensional control, contributes significantly to the longevity of the clip and helps save on maintenance costs.
- Hardness affects performance: E clips typically have a hardness range of 44 to 48 HRC, while SKL clips range from 42 to 47 HRC. These specifications influence their ability to withstand stress and fatigue over time.
