Custom Fabricated & Welded Plummer Block Housings
Product Description
Yile Machinery specializes in the manufacturing of custom-fabricated, heavy-duty plummer block housings. As an alternative to standard cast housings, our welded steel pillow blocks offer unparalleled design flexibility and superior strength for specialized and demanding applications.
We build directly from your engineering drawings to create a bearing housing that perfectly matches your dimensional and load requirements.
Why Choose a Fabricated Bearing Housing?
While cast housings are common, a fabricated steel housing provides distinct advantages, especially for OEM, MRO, and retrofit projects.
1.Complete Design Freedom:
Fabrication frees you from the constraints of casting molds. We can build a housing to any size, mounting footprint, or shaft centerline height, making it perfect for custom machine designs or replacing obsolete parts.
2.Exceptional Strength and Durability:
Constructed from high-strength structural steel plates, our welded housings can be engineered to be stronger and more impact-resistant than their cast counterparts. They are ideal for applications with extreme shock loads.
3.Cost-Effective for Custom & Low-Volume Needs:
Fabrication avoids the high upfront cost and long lead times associated with creating a new casting pattern. This makes it the most economical solution for one-off replacements, prototypes, or small production runs.
Our Fabrication & Precision Machining Process
We deliver a complete, ready-to-install solution by combining expert fabrication with high-precision machining.
Material Preparation: High-strength steel plates (e.g., S355/Q345) are cut to precise dimensions using CNC plasma or laser cutting.
Expert Welding: The components are assembled and welded by certified welders to create a single, robust weldment.
Stress Relief: The complete fabrication is heat-treated (post-weld heat treatment) to relieve internal stresses, ensuring long-term dimensional stability and preventing distortion.
Precision CNC Machining: The stress-relieved housing is then machined to final tolerances. This critical step includes:
Boring the internal diameter for the bearing seat.
Milling the split cap and base surfaces for a perfect fit.
Drilling and tapping mounting holes.
Applications for Fabricated Housings
Our fabricated plummer blocks are the preferred solution when standard housings won't work or won't last.
Equipment Retrofits & Upgrades: Replacing old, discontinued, or failed bearing housings on existing machinery.
Custom Machinery: Building unique equipment where standard bearing block dimensions are not suitable.
Extreme Environments: Applications in mining, steel production, and marine environments where maximum strength and impact resistance are required.
Large-Scale Systems: Supporting main shafts on large fans, conveyor drive pulleys, mills, and crushers.
