Product Description
Yile Machinery is a specialist manufacturer of large, custom-engineered cast steel bearing housings for heavy industrial applications. Our robust plummer block and pillow block housings are designed to provide superior load support, precise shaft alignment, and maximum protection for critical rolling bearings in demanding environments like steel mills, mining operations, and marine propulsion systems.
As an experienced OEM supplier, we deliver fully machined and ready-to-install bearing housings according to your exact drawings and specifications.
In heavy machinery, the bearing housing does more than just hold a bearing. It is a critical structural component that must:
Handle Massive Loads: Cast steel provides the high tensile strength and rigidity needed to support extreme radial and axial loads without deformation.
Ensure Accurate Alignment: Precise machining of the bearing seat and mounting surfaces is essential for proper load distribution and achieving maximum bearing life.
Dissipate Heat: The housing's mass and surface area help to draw heat away from the bearing during operation.
Protect the Bearing: It provides a secure enclosure that protects the bearing from contamination and allows for proper lubrication.
We offer a complete, single-source solution for producing high-quality bearing housings.
Expert Steel Casting:
We pour our housings from high-quality cast steel grades like ZG270-500, ZG310-570, and other custom alloy steels for enhanced strength and toughness.
Our foundry process ensures sound, defect-free castings with excellent structural integrity.
We can provide heat treatments such as normalizing or stress relieving to optimize the material's mechanical properties and ensure long-term dimensional stability.
Precision Machining Services:
Our machine shop is equipped with large CNC boring mills, vertical lathes, and milling centers to handle large-scale components.
We machine the bearing bore to tight tolerances (e.g., H7, H8) to guarantee a perfect fit.
Mounting surfaces are milled flat and parallel to ensure accurate installation.
We manufacture bearing housings for some of the most demanding equipment in the world:
Steel & Aluminum Rolling Mills: Housings for work roll and backup roll chocks.
Mining & Cement: Main bearing housings for crushers, grinding mills, and large conveyors.
Marine & Power Generation: Housings for propeller shafts (stern tubes) and large generator sets.
Pulp & Paper: Bearing housings for dryer cylinders and press rolls.
Whether you need an OEM component for new equipment or a high-quality replacement for an existing part, we can deliver. We can work directly from technical drawings or reverse-engineer a housing from a supplied sample.
