Product Features & Applications

Trailer axle wheel hub bearing housing, integrally cast from high-strength gray cast iron. Inner bore and flange mounting surface are precision CNC boring machined with high dimensional accuracy and good coaxiality. Reinforced thickened shell structure provides anti-impact and heavy load wear resistance. Compatible with FUWA, BPW 13/16 ton semi-trailer axles, widely used on flatbed, dump and box cargo semi-trailers. Mass ready stock, custom size & mold production available based on drawings.

1. Material & Casting Process

Made of high-toughness gray cast iron with uniform metallographic structure, high tensile strength to avoid fracture and deformation. Integral sand casting eliminates welding seams for better overall rigidity. Manual sand cleaning & deburring after casting, zero defects like air holes, sand holes and cracks. 100% flaw detection before delivery for stable quality.

2. Precision Machining Performance

Key bearing inner bore, flange mounting holes and end seal grooves are fully CNC boring processed. Mirror finishing on inner bore with tight tolerance ensures perfect bearing fit, no abnormal noise or overheating seizure during driving. One-time positioning machining for symmetric flange holes, good vehicle compatibility and easy assembly/disassembly.

3. Heavy-Duty Durable Structure Design

Multi-rib reinforced shell structure with upper & lower lubricating oil holes for axle grease pipeline. Thickened flange transition resists torsion under heavy bumpy mine & highway transport without cracking. Step sealing structure inside & outside cooperates with oil seal to block water & dust, extend bearing service life and reduce axle maintenance cost.

4. Vehicle Compatibility & Customization Service

Fit 3/4/5-axle flatbed, rear dump and box semi-trailers, compatible with 13/16Ton FUWA, BPW, LEAO mainstream axles. Custom mold casting available per customer axle drawings to adjust bore size, flange dimension and oil port. Mass self-production with abundant stock, supporting complete vehicle accessory supply, custom export packaging for overseas orders.
