| Layer thickness [mm]: | max. 0.03 |
2. Sliding layer
| Tin-lead-bronze | |
| Layer thickness [mm]: | 0.20–0.35 |
| Pore volume [%]: | approx. 30 |
3. Bearing back

| Steel thickness [mm]: | Variable |
| Steel hardness [HB]: | 100–180 |
1 The pores of the sliding layer are also filled with this lubricant mass.
1. /Fibre mixture thickness 0.01~0.03mm. It is the contact surface for the rotating shaft. Minute partides of the layer and the sintered bronze material combine to create a solid lubricant film, which coats the shaft.
2. Sintered bronze powder thickness 0.20*0.35mm,A special composition of powdered copper is thermally fused to the steel backing. This contact layer acts as an anchor for the layer and conducts the thermal build up away from the bearing surfaces.
3. Low-carbon steel backing. Setting the foundation of the bushings, the steel back provides exceptional stability, load carrying and heat dissipation characteristics.
