Wheel Bearing Hub Socket

1. High-Precision Design for Passenger Vehicle Applications

This is our wheel bearing hub socket, designed for passenger vehicles such as sedans and SUVs.

Wheel bearing assemblies in passenger vehicles typically have tight tolerances and limited installation clearance. Any deviation in socket concentricity may result in uneven force distribution and potential damage to the bearing interface.

Our socket is manufactured with a concentricity tolerance of ≤0.04 mm, ensuring precise alignment and safe engagement with the wheel bearing nut.

2. Deep Socket Design for Recessed Bearing Assemblies

The internal drive can be hex or spline, depending on customer requirements.

Socket depth ranges from 8 mm to 75 mm, allowing access to deeply recessed wheel bearing nuts commonly found in modern automotive hub assemblies.

Hardness is controlled at HRC 40–55, providing strong wear resistance and stable performance under repeated service operations. This ensures extended tool life even under frequent professional use.

3. Precision Surface Finish for Bearing Protection

Surface roughness is controlled at Ra ≤1.6 μm, ensuring a smooth contact surface during operation.

A rough or poorly finished socket surface may introduce scratches or stress marks on the bearing interface, potentially affecting assembly accuracy and generating operational noise or premature failure.

Our precision machining process ensures smooth insertion and stable torque transmission without damaging surrounding components.

We utilize in-house CNC machining systems to maintain strict dimensional accuracy and consistency.

We support OEM customization based on drawings or samples. The minimum order quantity (MOQ) is 100,000 pieces, with a lead time of approximately one month.
