Our professional wheel bearing customization service provides a full-process customized solution for passenger cars, commercial vehicles, construction machinery, and new energy vehicles, covering structural design, material selection, and process control. The core focus is on matching the customer’s load, speed, and operating environment requirements, while also considering industry trends such as lightweight design, long service life, and low noise.
- Core Customization Dimensions
1. Operating Condition Adaptation Customization
- Passenger Cars / New Energy Vehicles: Focusing on lightweight design, low noise, and high-speed performance, we offer customizable third-generation wheel hub bearing units (maintenance-free), integrated with ABS reluctor rings, adapted to the high torque output characteristics of pure electric vehicles, and optimized sealing structures to suit urban roads and high-speed driving conditions.
- Commercial Vehicles / Heavy Trucks: For heavy loads, long distances, and harsh road conditions, we customize double-row tapered roller wheel bearings, strengthening the roller material and raceway precision to improve impact load resistance, suitable for the frequent start-stop and bumpy conditions of dump trucks and logistics vehicles.
- Construction Machinery / Special Vehicles: For the dusty, muddy, and highly corrosive environments of mining and agricultural machinery, we customize heavy-duty sealed wheel bearings, using corrosion-resistant coatings and multiple sealing structures to prevent the intrusion of impurities.
2. Structural Design Customization
- Integrated Structure: According to customer needs, we integrate the wheel hub flange, sensor mounting seat, and brake disc mounting interface, reducing the assembly process of the entire vehicle and improving the stability of the assembly.
- Non-standard Size Customization: For modified vehicles and special models with non-standard journal diameters and mounting hole diameters, we customize the inner and outer ring dimensions to match the customer’s wheel hub assembly space limitations.
- Lubrication Solution Customization: Long-lasting grease is used for conventional operating conditions; high-temperature grease is customized for high-temperature conditions (such as school buses and sanitation vehicles with frequent braking); and waterproof grease is customized for wading conditions to extend the maintenance-free period.
3. Material and Process Customization
- Material Selection:
Standard operating conditions: High-carbon chromium bearing steel (GCr15) is used to ensure hardness and wear resistance;
High-load/corrosive operating conditions: Carburized bearing steel (20CrMnTi) or stainless steel (440C) is used to improve fatigue resistance and corrosion resistance.
- Heat Treatment Process: Customized quenching and tempering process parameters are used to optimize the hardness gradient (e.g., surface hardness HRC60-64, core hardness HRC30-40), improving the bearing’s resistance to spalling and deformation; isothermal quenching is used for large bearings to reduce heat treatment deformation.
- Surface Treatment: The inner and outer ring surfaces can be customized with anti-corrosion treatments such as phosphating, galvanizing, and Dacromet to meet the needs of corrosive environments such as coastal and saline-alkali areas.
- Customized Service Process
- Requirements Matching: The customer provides core indicators such as vehicle model parameters, operating condition data (load, speed, temperature, environment), installation dimensions, and service life requirements.
- Solution Design: Engineers conduct structural simulation and life verification, and output customized design solutions and technical drawings.
- Sample Prototyping: Small batches of samples are produced and subjected to bench testing (e.g., durability testing, noise testing, sealing performance testing).
- Verification and Optimization: Samples are installed on vehicles for road testing, and design parameters are adjusted based on test data until customer requirements are met.
- Mass Production: A dedicated production batch is established, with full quality traceability and factory inspection reports provided.
- Core Advantages
Precise Matching of Operating Conditions: Avoids the problems of “over-engineering” or “under-engineering” with general-purpose bearings, reducing the customer’s overall cost of ownership.
Full-Process Technical Support: One-stop service from design to after-sales, solving customers’ technical selection challenges.
Rigorous Quality Control: High-precision equipment is used for key processes (such as grinding and assembly) to ensure rotational accuracy and clearance control within ±2μm, meeting the performance requirements of high-end vehicles.
- Applicable Customer Scenarios
- New model development for vehicle manufacturers (passenger cars, commercial vehicles, new energy vehicle companies);
- Non-standard wheel hub assembly matching for modified car manufacturers and special vehicle customization companies;
- Equipment upgrades for harsh operating conditions for construction machinery and agricultural machinery manufacturers.
