Heavy-Duty Split Plummer Block Housings (Pillow Blocks)

Yile Machinery is a leading manufacturer of large-scale, cast steel split plummer block housings. These robust housings are engineered to support high-capacity spherical and cylindrical roller bearings in the most demanding industrial applications.

Built from high-strength steel castings and finished with precision CNC machining, our plummer blocks provide a reliable foundation for rotating equipment in steel mills, mines, and processing plants.

The Advantage of Cast Steel Split Housings

Split plummer blocks are the industry standard for heavy-duty applications due to their unique combination of strength and serviceability.

1.Ease of Installation & Maintenance:

The split housing design (with a separate cap and base) allows for easy installation, inspection, and replacement of bearings without needing to remove the entire shaft. This is critical for maintenance efficiency and reducing equipment downtime.

2.uperior Strength for Heavy Loads:

Manufactured from high-strength cast steel (e.g., ZG270-500) , our housings offer significantly higher impact resistance and load-bearing capacity than standard cast iron housings. They are designed to withstand the extreme shock loads and vibrations common in heavy industry.

3.Versatility for Large Roller Bearings:

These housings are specifically designed to accommodate high-capacity self-aligning bearings, such as spherical roller bearings. This allows them to handle heavy radial loads and manage minor shaft misalignment, extending bearing life.

Manufacturing Process: From Casting to Precision Machining

Every housing we produce undergoes a rigorous two-stage manufacturing process to ensure quality and performance.

• Step 1: Quality Steel Casting:

We begin with a high-integrity steel casting, produced in our foundry to be free of voids and internal defects. The raw casting forms the robust body of the housing.

• Step 2: Precision CNC Machining:

The casting is then transferred to our CNC machining centers where all critical surfaces are finished to tight tolerances. This includes:

• The internal bore for the bearing seat.

• The flat mating surfaces of the cap and base.

• The mounting feet for accurate alignment.
