Abstract: A slide bearing is described with a bearing metal layer on copper basis as applied to a carrier and a running layer made of an alloy of aluminum and tin which is applied physically onto the bearing metal layer in vacuum. In order to combine favorable resistance against wearing with a low inclination towards jamming with advantageous tribological properties it is proposed that the bearing metal layer consists of an alloy with 4 to 8% by weight of tin, 0.6 to 1% by weight of silver, 1 to 2% by weight of an iron phosphide and 0 to 0.15% by weight of carbon, preferably in the form of graphite, and the remainder of copper.

Abstract: The surface of a lining member 3 is formed with a multiplicity of uneven surfaces 3a. The entire surface of the lining member 3 is coated by an intermediate layer 4 which comprises Ni. The surface of the intermediate layer 4 is additionally coated by an overlay layer 5 which comprises an Sn alloy. The lining member 3 has a surface roughness t.sub.1, as a result of forming the uneven surfaces 3a, which is chosen to be in a range from 2 to 8 .mu.mRz, and a thickness t.sub.2 of the intermediate layer 4 is chosen to be in a range from 0.01 to 0.6 .mu.m. When a sliding bearing 1 is heated, the overlay layer 5 and the intermediate layer 4 chemically react with each other to produce an Sn--Ni compound. As the overlay layer 5 becomes abraded, the Sn--Ni compound 6 will be exposed on the sliding contact surface. However, the described choice prevents the Sn--Ni compound from being exposed across the entire region of the sliding contact surface, thus improving the anti-seizure resistance of the sliding bearing 1.

Abstract: A helical groove 1B is formed in the sliding surface 1A of a sliding bearing 1 over the entire axial region thereof. To establish the height of a peak 1a defined by the helical groove 1B, an imaginary reference line L extending parallel to the axis is formed which is determined such that the total cross-sectional area of all the peaks 1a is equal to the total cross-sectional area of all the valleys 1b when the helical groove 1B is considered in axial section. A height, as measured from the reference line L to the top 1a' of the peak 1a is chosen in the range of from 1 to 8 .mu.m. The space created by forming the valleys 1b allows the supply of lubricant oil to be increased, thereby simultaneously achieving a reduction in the frictional resistance and the occurrence of an impact sound.
