Custom HT250 Gray Iron Bearing Housings for Heavy Industrial Equipment

MetalKeen manufactures custom HT250 gray iron bearing housings for industrial machinery requiring excellent vibration damping, wear resistance, dimensional stability, and reliable bearing support.

Our bearing housings are produced using high-quality HT250 gray cast iron through precision sand casting, CNC machining, and comprehensive quality inspection. HT250 offers excellent rigidity, machinability, thermal conductivity, and damping characteristics, making it one of the most widely used materials for industrial bearing housings. Major bearing manufacturers commonly use gray cast iron as the standard housing material because it effectively absorbs vibration while maintaining structural stability.

MetalKeen manufactures bearing housings according to customer drawings or OEM specifications and can supply fully machined housings, bearing seats, lubrication holes, sealing grooves, and assembled bearing housing units.

What Is an HT250 Bearing Housing?

An HT250 bearing housing is a cast iron mechanical component that supports rolling bearings and accurately positions rotating shafts. It maintains shaft alignment, protects bearings from contamination, and transfers operational loads to the machine frame.

HT250 gray iron is widely selected because it combines:

• Excellent vibration damping

• Good wear resistance

• High compressive strength

• Outstanding machinability

• Stable dimensional performance

• Cost-effective manufacturing

These properties make it ideal for bearing housings used in heavy industrial machinery.

Typical Applications

Our bearing housings are widely used in:

• Paper Machinery

• Conveyor Systems

• Mining Equipment

• Gearboxes

• Pumps

• Fans & Blowers

• Steel Plant Equipment

• Cement Equipment

• Agricultural Machinery
