Lead- and tin-based bearing alloys
They are used for casting sliding bearing shells used in high-speed engines, mills, turbines, rollers, compressors, railroad cars, as well as lining the sliding surfaces of various mechanical components.
Bearing alloys for centrifugal and static casting are characterized by:
- a low coefficient of friction between a shaft usually made of steel and a pan poured from a suitably selected alloy,
- high hardness, abrasion resistance and resistance to high pressure at elevated temperatures,
- good thermal conductivity,
- resistance to corrosive agents
- good casting and machining properties
The alloys are available in the form of ingots with dimensions of about 60 x 130 x 600 mm and a weight of 23 ±3kg
Normy PN-ISO 4381:1997, PN-ISO 4381/AK:1998, PN-82/H-87111
Among others, we offer the following bearing alloys according to standards: PN-82/H-87111* or PN-ISO 4381:1997**.
