A telescopic rail comprising:
- a first rail element,
- a second rail element which is mounted on the first rail element so as to be linearly displaceable via a rolling element bearing or a plain bearing, and
- optionally a third rail element which is mounted on the first or the second rail element so as to be linearly displaceable via a rolling element bearing or a plain bearing,
- wherein at least the first rail element is manufactured from a rolled steel sheet and the surface of the steel sheet has a surface layer produced by a nitriding process with a nitriding hardness depth (Nht) in the range of 0.05 mm to 0.6 mm.
