Bearing alloys based on lead and tin


Standards: PN-ISO 4381:1997, PN-ISO 4381/AK:1998, PN-82/H-87111

They are used for bearing shells casting of slide bearings, which are used in high-speed engines, mills, turbines, rolls, air-compressors, railway cars, as well as lining of slide surfaces of mechanical parts.  Bearing alloys for centrifugal and static casting are characterized by:

·    Low coefficient of friction between a shaft (made usually of steel) and a bearing shield made of suitably chosen alloy

·    Hardness, abrasion resistance and  high load strength in higher temperatures,

·    Good thermal conductivity,

·    Corrosion resistance

·    Good casting and cutting properties

Alloys are available In form of jumbos and pig sows with dimensions: app. 60 x 130 x 600 mm and weight  23 ±3kg.

Our assortment covers following alloys in compliance with: PN-82/H-87111* or PN-ISO 4381:1997**.
