ABSTRACT:
The stamped-metal clip is suitable for use with an endless track belt cooperating with slide rails. The clip comprises a main portion having a hardened bearing surface to be engaged against at least one of the slide rails. The bearing surface has a hardness greater than 35 HRC, preferably between 40 and 60 HRC. The clip further comprises an unhardened fastening portion comprising two curved wings to clamp the main portion to the track belt without rupture. These curved wings have a hardness smaller than the hardness of the bearing surface, preferably smaller than 35 HRC. The hardness of the bearing surface makes it resistant to wear and friction and the smaller hardness of the wings enables the clip to be clamped to the track belt without rupture.
