Custom Heavy-Duty Bearing Housings & Pedestals
Product Description
Yile Machinery is your integrated manufacturing partner for large, custom-engineered steel castings, specializing in heavy-duty bearing housings, support pedestals, and bearing chocks. We deliver fully-machined, ready-to-install components for the world's most demanding industries, from steel mills to marine propulsion.
Our unique capability combines a state-of-the-art steel foundry with a large-scale precision machine shop, allowing us to manage your project from raw material to finished component under one roof.
From Raw Casting to Precision Component: Our Integrated Process
Creating a large bearing housing that can withstand immense forces requires more than just casting metal. It demands a multi-stage process where quality is controlled at every step.
Casting & Material Expertise
It begins in our steel foundry. We pour high-integrity carbon and alloy steel castings (such as ZG270-500, ZG35CrMo, or your specified grade) using optimized casting methods to ensure a sound, defect-free structure.
Advanced Heat Treatment
After casting, each component undergoes a critical heat treatment cycle (e.g., annealing, normalizing, or quenching & tempering). This refines the grain structure of the steel, relieving internal stresses and dramatically improving its strength, toughness, and machinability.
Large-Scale Precision Machining
The heat-treated casting is then moved to our CNC machining center. Using large CNC boring mills, gantry mills, and lathes, we machine all critical features to your exact specifications. This includes:
Precision boring the bearing seat to a tight tolerance.
Milling flat and parallel mounting surfaces.
Drilling and tapping bolt holes.
Key Features & Benefits
Custom Engineered Solutions: We don't sell off-the-shelf parts. We manufacture complex components based on your specific drawings and technical requirements.
Superior Load Capacity: Our cast steel housings offer significantly higher strength and impact resistance compared to cast iron, making them essential for applications with high shock loads.
Guaranteed Dimensional Accuracy: Precision CNC machining ensures perfect alignment, simplifies assembly, and extends the life of your bearings and shafts.
One-Stop-Shop Manufacturing: By controlling the entire process, we reduce lead times, lower costs, and ensure consistent quality from foundry to final inspection.
Applications for Large Machined Castings
Our expertise is trusted across numerous heavy industries for critical components:
Steel & Rolling Mills: Bearing chocks, mill stand housings, drive-side pedestals.
Mining & Cement: Trunnion bearing housings for ball mills and kilns, crusher frame components.
Power Generation: Turbine and generator bearing pedestals.
Marine & Shipbuilding: Stern tube bearing housings, engine bedplates.
Heavy Industrial Gear Drives: Large, custom gearbox housings.
