- Product Introduction
Self-Tensioning Elastic Rail Clips are high-performance railway fastening components designed to provide continuous and automatic clamping force between the rail and sleeper. Unlike conventional fasteners, these elastic clips maintain stable tension throughout service life, effectively compensating for rail movement, vibration, and thermal expansion.
Widely applied in high-speed railways, heavy-haul lines, metro systems, and conventional rail tracks, self-tensioning elastic rail clips play a critical role in ensuring track gauge stability, operational safety, and long-term durability.
