Conclusions
-
1.
A technique has been developed for bulk-surface hardening of heavily loaded roller bearing rings.
-
2.
It was found that rings of heavily loaded roller bearings for railroad cars manufactured from high-carbon steel with controlled hardenability and subjected to bulk-surface hardening have a higher structural strength than rings of ESR steel ShKh15SG.
