2.1.3. The top layer

The top layer, the chemical composition of which is given in table 2, is applied to the bearing layer. The thickness of the upper layer or any additional layer between the bearing layer and the upper layer is determined by agreement between the manufacturer and the consumer.

2.2. Reference guide to the selection of materials and their properties

Guidance for the selection of the hardness of the bearing alloy and its use are shown in tables 3 and 4.

Characteristics and main use in high-speed engines
Minimum shaft hardness, HB
PbSb10Sn6
Soft, corrosion-resistant, relatively good properties with limited lubrication, low fatigue strength; works with hard and soft shaft. 180
