Elastic Rail Clip

Elastic Rail Clip

We produce and supply various elastic rail clips, spring blades and SKL tension clamps.

We produce SKL tension clamps with sizes from steel bar dia. 12mm to 15mm, ranges from SKL1, SKL3, SKL12, SKL13, and SKL14, etc.
Steel DIN 17221, BS970, GB/T 4357 and GB/T 4358 are all available.
The hardness of finished product is 42-47 HRC.
When spring deflection is 9.1mm, fatigue life is up to 5 million cycles without breaking.

We produce Nabla clips by alloy spring steel.  Their hardness is 51-55 HRC and they have excellent elastic property.  With load 2500daN, after two first tests, variation of height after releasing is only 0.45mm and after three more tests, there is only 0.1mm variation of height.  The finished Nabla clips can be painted red or other colors according to the requirements of our clients.
