Copper: Balance

Iron: 1% Max

Carbon: 3% Max

Tin: 9-11%

Max. Other Elements. 2%

Open Porosity Minimum: 20-27%

Minimum Oil Content: 18-24%

Minimum Radial Crushing Strength K: 120-180 N/mm²

Nominal Density: 6-7g/cc

Maximum static load: 35-65 N/mm²

Maximum dynamic load: 10-18 N/mm²

Maximum velocity: 5-6 m/s

Maximum PV factor*: 1.8

*PV factor = Pressure (N/mm²) x bearing surface velocity (m/s).

Pressure is calculated as load (N) / Projected area (internal diameter x Length) (mm)
