High-Strength Ductile Iron Bearing Housing | Material Handling Equipment Solutions

The load wheel bearing housing of a forklift must withstand operational loads while maintaining bearing positioning accuracy. Manufactured from ductile iron with precision-machined bores, it represents a typical industrial load-bearing structural component.

The manufacturing challenges of balance wheel bearing housings lie in establishing a stable datum system from casting blank to finished product to ensure subsequent machining accuracy. The center bearing bore must meet coaxiality and surface roughness requirements for proper bearing installation and operation. The positional tolerance of corner screw holes and side threaded holes directly affects assembly quality with the chassis. Finally, parallelism control between bottom and top surfaces is critical to prevent runout after installation.
The cutting characteristics of high-strength ductile iron also present challenges: the high-strength spheroidal graphite accelerates tool wear, requiring appropriate cutting parameters and tool selection; although the material itself has good damping characteristics, adequate clamping rigidity must still be maintained during machining to prevent chatter marks from compromising surface finish.
WKPT possesses multi-axis machining capabilities for holes on multiple surfaces, sufficient machine rigidity and precision to control positional tolerances, extensive process planning expertise for cast iron characteristics, and consistent surface treatment capabilities to provide corrosion protection.
