FIELD: machine building.
SUBSTANCE: present invention relates to mechanical system (1) comprising bearing (4) and shaft (10) connected to bearing (4), which is equipped with internal combustion engine, wherein said mechanical system (1) is subject to action of average contact pressure with value less than 200 MPa, characterized by that shaft (10) contains at least one zone (12), provided: anti-seized surface coating (20) having surface hardness which is at least twice greater than surface hardness of bearing (4), and micro-texturing (30), which is formed by multiple separate microcavities (31, 32, 33, 34, 35), distributed within said zone (12). Present invention also relates to a method of making said mechanical system (1).
EFFECT: technical result is the proposal of a satisfactory solution in terms of resistance to galling and wear.
