Forged Wheel Hubs
A wheel hub carries vertical load, cornering side force and braking torque through its bearing seats. Runout at the flange face translates directly into brake judder and uneven tyre wear, so dimensional discipline matters as much as strength.

Bearing Seats and Runout
Inner and outer bearing seats are machined in one setup so they stay coaxial, and flange face runout is measured on every setup change. This is the difference between a hub that runs quietly for a decade and one that returns as a warranty claim.
- Coaxial bearing seats, single setup
- Flange face runout controlled
- Stud hole pattern to PCD drawing
- Balanced material distribution
Stud Holes and Mounting Interface
Stud hole pattern, PCD and pilot diameter are machined to the wheel specification and gauge verified. Hole edges are chamfered so stud seating is repeatable when the wheel is torqued in service.
Material and Duty
SAE 1045 and EN8 normalised suit trailer duty; alloy grades quenched and tempered are used where axle loads and braking energy are higher.
Wheel Hub Capability and Critical Fits
A wheel hub carries vertical load, cornering force and braking torque through its bearing seats, and any runout at the flange face translates directly into brake judder and uneven tyre wear. The bearing seats and the flange face are therefore machined and verified as a related set rather than as independent dimensions.

| Flange face runout | Verified per setup |
| Stud pattern | Machined to drawing PCD, gauge checked |
Why Bearing Seats Are Machined in One Setup
Inner and outer bearing seats must be coaxial. Machined in a single setup they hold that relationship inherently; machined separately, any misalignment forces the bearings to run out of line, generating heat and shortening life. Stud hole pattern, pitch circle diameter and pilot diameter are machined to the wheel specification and gauge verified, with hole edges chamfered so stud seating is repeatable when the wheel is torqued in service.
- Coaxial bearing seats machined in one setup
- Flange face runout measured at every setup change
- Stud holes chamfered for repeatable seating
- Material matched to axle load and braking energy
