Product Description
1. Precision Spline Drive for Wheel Bearing Applications
This is our truck wheel bearing socket, designed for heavy-duty wheel bearing nut applications. Unlike standard hex fasteners, truck wheel bearing nuts typically use spline-type interfaces.
Our socket features a matching internal spline profile, providing multi-point contact with the nut. Compared with hex drives, spline engagement distributes torque more evenly, reducing localized stress and preventing slippage or damage during operation.
2. Reinforced Structure for High Torque Applications
Spline specifications, including module and tooth count, are fully customized according to customer requirements.
Wall thickness ranges from 5 mm to 12 mm, providing a reinforced structure designed for extremely high torque loads. Wheel bearing nuts require significantly higher tightening and removal forces than standard fasteners, and insufficient wall thickness may result in deformation or fracture.
Our design ensures a high structural safety margin for heavy-duty service conditions.
3. High Hardness and Long Service Life Design
Hardness is controlled at HRC 45–58, providing excellent wear resistance under repeated high-torque operation.
Fatigue life is tested to ≥1,000,000 cycles under standard working conditions, ensuring long-term durability in professional workshop environments.
To put this into practical terms, even with frequent daily use in repair shops, the service life is significantly extended due to the combination of high-strength alloy steel and optimized heat treatment.
We use premium materials such as 42CrMo and 40CrNiMo, both known for high strength, toughness, and fatigue resistance.
The minimum order quantity (MOQ) is 100,000 pieces. Third-party inspection is supported upon request.
