Custom Q355D Steel Bearing Housing for Heavy Industrial Equipment
MetalKeen manufactures custom Q355D steel bearing housings for demanding industrial applications requiring high structural strength, precise bearing support, and long-term operational reliability.
A bearing housing provides the structural support for rolling bearings, ensuring accurate shaft alignment while transferring radial and axial loads into the machine frame. Proper housing design also improves lubrication retention, sealing performance, and bearing service life.
Manufactured from Q355D high-strength structural steel, our bearing housings offer excellent weldability, impact toughness, and dimensional stability. Every housing is produced through CNC machining, precision boring, milling, drilling, welding (if required), and comprehensive dimensional inspection according to customer drawings.
MetalKeen supplies OEM bearing housings for paper machinery, mining equipment, conveyors, steel mills, gearboxes, pumps, hydraulic systems, and other heavy-duty rotating equipment.
What Is a Bearing Housing?
A bearing housing is the structural component that supports and locates a bearing while maintaining proper shaft alignment. It transfers operational loads from the rotating shaft into the machine frame, retains lubricant, and protects the bearing from dust, moisture, and contaminants, contributing directly to machine reliability and bearing life.
