One-Piece Integrated Wheel Hub Assembly FDZ9012934006901 Factory Press-Fit Bearing Module For Long-Distance Haul Trucks

Product Description

FDZ9012934006901 wheel hub assembly is an integrated wheel bearing unit pre-installed for heavy-duty truck drive axles. It combines cast iron hub housing, precision roller bearing set and fully pressed galvanized wheel studs into a single ready-to-fit component. Mounted on vehicle axle spindles, it supports the full weight of the truck and enables smooth rotation of wheels while transmitting driving torque. The bearing inner race is precision interference-fitted inside the hub during production, eliminating manual bearing pressing work during maintenance. All stud positions, mounting hole layout and bearing size strictly follow OEM standards for direct bolt-on replacement without on-site machining.

Key Product Advantages

• High-strength ductile cast iron hub body with annealing heat treatment, strong impact resistance and anti-fatigue performance to withstand full-load bumpy road operation without cracking.
• Pre-pressed heavy-duty roller bearing unit inside the hub, precise clearance control, low rolling resistance and stable rotation with minimal noise at high driving speeds.
• Multiple hot-dip galvanized wheel stud bolts fixed firmly to the flange, anti-rust and high tensile strength, avoiding thread slipping or breakage under heavy load.
• Hollow weight-reduction structural design on hub side walls, balancing overall weight while maintaining rigid load-bearing capacity to reduce unsprung mass of the axle.
• Standard concentric inner bore and evenly distributed mounting holes, perfectly matching original axle spindle dimensions to guarantee coaxiality and prevent wheel wobble.
