Grey Iron Bearing housings support your bearings, protect them from contaminants while keeping in lubricant, and can also house monitoring equipment. Essentially, they provide customizable mounted bearing solutions and help maximize performance, service life and cost-efficient maintenance of the incorporated bearing. Custom grey iron bearing blocks are widely used in heavy duty industry, like manufacturing plant, machinery repair ships, farms.

 

OEM & ODM Cast Iron Bearing Housings

Hengchang is the leading producer of gray, ductile iron in China, melting more than 6000 tons per year, with more than 15 years experience. Our custom products widely use in different area, such as water pumps, valves, oil & gas, metallurgy, municipal, rail roads, sport, foodservice industry, automotive, agriculture machine, construction, etc. Welcome to visit Hengchang, the leading manufacturer in the foundry industry, and learn how our quality, consistency and service to support you win more market shares.

Cast iron is a class of iron-carbon allys with a carbon content more than 2%. Its usefulness derives from its relatively low melting temperature. The alloy constituents affect its color when fractured: white cast iron has carbide impurities which allow cracks to pass straight through,grey cast iron has graphite flakes which deflect a passing crack and initiate countless new cracks as the material breaks, and ductile iron has spherical graphite "nodules" which stop the crack from further progressing.

Carbon (C), ranging from 1.8 to 4 wt%, and silicon (Si), 1–3 wt%, are the main alloying elements of cast iron. Iron alloys with lower carbon content are known as steel.

 

Cast iron tends to be brittel, except for malleable cast irons. With its relatively low melting point, good fluidity, castability, excellent machinability, resistance to deformation and  wear resistance, cast irons have become an engineering material with a wide range of applications and are used in pipes, machines and automotive industry parts, such as cylinder heads,, cylinder blocks and cylinder blocks and gearbox. It is resistant to damage by oxidation.
