A bearing housing assembly is a complete support unit designed to locate, protect, and support rolling bearings while allowing a shaft to rotate smoothly. It typically consists of the housing body, bearing, seals, covers, fasteners, and lubrication features assembled into one integrated system.
The housing transfers loads from the rotating shaft into the machine frame, maintains shaft alignment, retains lubricant, and protects the bearing from dust, moisture, and other contaminants. Proper housing selection has a direct impact on bearing life, vibration, maintenance intervals, and overall machine reliability.
A properly designed bearing housing improves both equipment performance and maintenance efficiency.

Critical features such as bearing bores, mounting faces, and seal grooves are machined with tight tolerances to ensure accurate bearing fit and reliable shaft alignment.
Typical manufacturing capabilities include:
Housing Size: Customized
Bearing Bore: According to Drawing
Mounting Configuration: Customized
Bore Tolerance: According to Drawing
Coaxiality: According to Drawing
Flatness: According to Drawing
Lubrication Type: Grease or Oil
OEM Manufacturing: Supported
Material selection depends on operating load, environmental conditions, and service life requirements.
Available materials include:
Gray Cast Iron
Ductile Iron
Cast Steel
Carbon Steel
Stainless Steel 304
Stainless Steel 316
Cast iron is widely used because of its rigidity and vibration damping, while cast steel is preferred for higher impact loads. Stainless steel housings are commonly selected for corrosive or hygienic environments.
MetalKeen manufactures bearing housings in a variety of configurations.
Available types include:
Pillow Block Housing
Flange Bearing Housing
Split Plummer Block Housing
Cartridge Housing
Take-Up Housing
Custom CNC Machined Housing
The appropriate housing type depends on shaft size, mounting method, available installation space, maintenance requirements, and operating conditions.
Effective lubrication and sealing are essential for extending bearing service life.
Available options include:
Grease Lubrication
Oil Lubrication
Automatic Lubrication Ports
Labyrinth Seals
Contact Seals
Oil Seals
End Covers
Proper sealing prevents contamination while retaining lubricant, reducing wear and minimizing maintenance.
Available surface treatments include:
Industrial Painting
Powder Coating
Black Oxide
Zinc Plating
Passivation (Stainless Steel)
Anti-Corrosion Coating
Surface finishing improves corrosion resistance and enhances long-term durability in harsh industrial environments.
Custom bearing housing assemblies are widely used in:
Paper Machinery
Pulp Processing Equipment
Conveyor Systems
Mining Equipment
Industrial Gearboxes
Pumps
Compressors
Steel Processing Lines
Agricultural Machinery
Marine Equipment
Power Transmission Systems
Heavy Industrial Machinery
