P4023Z Bronze with graphite Sintered Bearing Material

High-density bronze-graphite sintered bearing material, oil-impregnated per BS 5600-5.1:1988 / ISO 5755-1:1987. Combines the strength of higher density with graphite solid lubrication for demanding self-lubricating bearing applications.

Chemical Composition (BS 5600-5.1:1988)

Element	Content	Unit
C total	0.5–2.0	%
Cu	Balance
Sn	9–11	%
Other elements	—	≤2

Mechanical & Physical Properties

Property	Unit	Value
Open porosity (P)	%	≥17
Radial crush strength (K)	N/mm²	≥160
Density (—)	g/cm³	6.8
Relative density (—)	%	80
Coefficient of linear expansion (μz)	10⁻⁶K⁻¹	18

The Z suffix indicates the material has been impregnated with liquid lubricant per ISO 5755. The liquid lubricant content shall be not less than 90% of the measured open porosity. Open porosity and radial crush strength are mandatory values as specified in BS 5600-5.1:1988 / ISO 5755-1:1987 / BS EN ISO 5755:2022.
