Engine bearing layers and their functions

Steel back supports bearing structure, provides its rigidity and press fit under severe conditions of increased temperature and cycling loads.
Intermediate layer (lining) is a layer located between the steel back and the overlay

Materials Basic Quality Required

1.Antifriction: The material has a low coefficient of friction
2.Abrasion resistance: Anti-friction properties of materials, usually expressed in terms of wear rate
3.Seizure resistance: Heat resistance and anti-adhesion properties of materials
4.Embeddedness: The material contains the hard particles embedded, thereby reducing the performance of the sliding bearing surface scratches or abrasive wear
he sliding bearing surface scratches or abrasive wear
