B101 Thin-walled motor bearings

Bimetallic thin-walled bearing shells with AlSn slide layer
AISn – A20 material consists of two metal layers the steel base is surfaced with the slide lining material AlSn20Cu1.
The assembly is ideally suited for use in hydrodynamic lubrication condition for static and dynamic load. The material having the good slide behaviours exhibits both good fatigue strength and good corrosion resistance. In the limiting friction conditions the material shows good working adaptation.
The face hardening of the pin improves the life service. A heat treatment above 52 HRc is recommended.
Due to their excellent behaviour they are used in slide fits of gasoline and Diesel engines.
