Heavy-Duty Split Pillow Block Bearing Housings with Bronze Bushings
Product Description
Yile Machinery is a manufacturer of large, custom-engineered cast steel pillow block (also known as plummer block) housings. These robust housings are designed to support rotating shafts in the most demanding industrial environments, utilizing a durable bronze bushing as the bearing surface.
Our housings are built to your exact specifications, providing a reliable and long-lasting solution for heavy machinery in mining, marine, and manufacturing sectors.
Why a Split Housing with a Bronze Bushing?
This combination offers a unique set of advantages for heavy-duty, low-speed applications.
1.Ease of Installation and Maintenance:
The split housing design allows the housing to be installed or removed without having to dismount other components from the shaft. This is essential for "trapped" shafts (e.g., between a drive and a gearbox) and dramatically reduces maintenance downtime.
2.Superior Performance in Harsh Environments:
The bronze bushing acts as a plain bearing (or journal bearing), which excels in high-load, low-speed conditions. Bronze offers:
Excellent wear resistance.
The ability to embed small contaminants, protecting the shaft from damage.
Good performance in high-temperature or poorly lubricated conditions.
3.Robust Cast Steel Construction:
We use high-strength cast steel to manufacture the housing. Compared to standard cast iron, cast steel provides superior tensile strength and impact resistance, making it essential for applications with heavy shock loads.
Key Features & Specifications
Fully Custom Manufactured: Produced from your drawings or specifications to ensure a perfect fit for new or replacement applications.
Split Housing Design: Two-piece (upper and lower) housing bolted together for easy assembly and inspection.
Material (Housing): High-strength cast steel (e.g., ZG270-500) for maximum toughness and load-bearing capacity.
Material (Bushing): High-quality bearing bronze alloy (e.g., Tin Bronze, Aluminum Bronze) chosen for your specific load and speed requirements.
Precision Machining: All critical surfaces, including the housing bore and mounting feet, are precision machined for accurate alignment.
Lubrication Provisions: Designed with grease nipples and internal oil grooves to ensure proper lubrication of the bearing surface.
Applications in Heavy Industry
Our custom split pillow block housings are trusted in some of the world's most demanding machinery:
Mining & Cement: Main support bearings for ball mills, SAG mills, rotary kilns, and large crushers.
Marine & Shipbuilding: Support blocks for propeller shafts and rudder stocks.
Power Generation: Support bearings for large fans, turbines, and generator shafts.
Steel Mills: Bearings for rolling mill stands and conveyor lines.
Pulp & Paper: Housings for dryer cans and pulp processing equipment.
