FIELD: machine building.
SUBSTANCE: invention relates to the sliding elements, such as inserts or bushings of the bearings. The sliding element (20) of the bearings comprises a steel base (22), a base layer (24) out of sintered metal powder, located on base (22) and containing copper, tin, bismuth and solid particles (40) comprising Fe3P or MoSi2 in amount from 0.2 wt % to 5.0 wt % with average volume size D50 not exceeding 10 mcm, and hardness at least 600 HV 0.05 at temperature 25°C. Under one option on the base layer (24) a tin layer (26) is sprayed. Between the base layer (24) and tin sprayed layer (26) the nickel separating layer (42) can be located, and tin and nickel intermediate layer (44) between the nickel separating layer (42) and tin sprayed layer (26). Under another option the sliding element (20) contains either deposited aluminium coating (30), or polymer coating (28) applied directly on the base layer (24). The polymer coating (28) contains solid particles (48) out of, for example, Fe2O3.
EFFECT: invention increases wear-resistance of the sliding elements of the bearings for long time.
