FZ23 Bronze Base (CuSn5Pb5Zn5) Sintered Bearing Material

FZ23 is a leaded tin bronze (CuSn5Pb5Zn5) base, oil-impregnated sintered self-lubricating bearing material per Soperb Oilites standard. Also known as SAE660 equivalent. The lead content provides excellent conformability and emergency running properties for automotive and industrial bearing applications.

Chemical Composition (Soperb Oilites / ISO 2795 (DIN 1850 Part 3))

Element	Content
Cu	Balance
Sn	4.0~6.0%
Pb	4.0~6.0%
Zn	4.0~6.0%
Other	≤1.5%

Mechanical & Physical Properties

Property	Value
Oil Retaining	12%~18%
Radial Crushing Strength	>150 MPa (at 18% oil), >200 MPa (at 12% oil)
Max. Linear Speed	4 m/s
Max. PV	8 N/mm² · m/s
