Select high-precision, factory-direct components engineered to surpass OEM tolerances for heavy-duty commercial haulage, premium passenger cars, and specialty excavators.
The global automotive supply chain is undergoing structural changes, driving the demand for Generation 3 wheel hub assemblies and heavy-duty chassis links to unprecedented levels. In an era where vehicle electrification, dynamic load efficiency, and carbon neutrality dominate procurement mandates, top-tier automotive designers must deliver components that optimize unsprung mass without sacrificing structural integrity.
As commercial shipping hubs face demanding delivery timelines, downtime translates directly to lost revenue. High-performance wheel hub assemblies reduce rolling resistance, preserve overall tire alignment, and mitigate structural bearing failure risks under variable temperatures.
Electric vehicle architectures demand components that withstand high starting torque and heavier battery loads. Integrated wheel hub systems must combine forged outer rings with optimized bearing preloads to offset the increased stresses of regenerative braking systems.
By using multi-lip rubber cassette seals, precision induction hardening of outer raceways, and advanced metallurgical verification, modern factories ensure that every component guarantees structural reliability under extreme radial and axial pressures.
Our commitment to technical excellence is proven by quantitative benchmarks. We ensure every chassis product stands up to the harshest real-world operating environments.
A State-Owned Holding National High-Tech Enterprise
Founded in 2004, Shenzhen Partix Auto Co., Ltd. has grown to become a cornerstone of automotive precision manufacturing. Headquartered with key manufacturing plants in Zhucheng, Shandong—near Weifang (the kite capital of China) and within the one-hour economic circle of Qingdao Port—our shipping networks link directly to key global industrial terminals.
We operate as a state-owned holding listed company and have earned the prestigious title of “National Intellectual Property Demonstration Enterprise”. Since 2006, industry experts have consistently recognized Partix Auto as one of the “National Top 100 Automotive Parts Suppliers.”
We specialize in the design, development, and high-volume manufacture of premium fluid pipelines, vehicle suspension systems, and rubber vibration dampers. Our products, which include control arm bushings, heavy-duty air springs, engine mounts, and complex chassis components, are used across the passenger car, commercial transit, and industrial construction sectors.
The lifespan of a wheel hub assembly depends on two factors: the chemical composition of the steel and the precision of its assembly preload. At Partix Auto, our engineering team utilizes high-frequency induction hardening on specific surfaces, ensuring a hardened depth of 2.5mm to 3.5mm. This process creates a wear-resistant exterior shell while keeping the interior core ductile enough to withstand shock loads.
We use premium vacuum-degassed GCr15 high-carbon chromium bearing steel. This minimizes non-metallic inclusions, preventing subsurface fatigue cracking and extending the bearing’s operational life under continuous radial loads.
Our Generation 3 wheel hub designs feature integrated, high-temperature magnetic encoders. These provide real-world ABS and ESP signals down to zero speed, remaining reliable even during sudden brake heating cycles.
We prevent contamination using custom fluororubber (FKM) multi-lip cassette seals. These seals keep dust, road salt, and water out while retaining premium synthetic grease, keeping friction losses low over the long term.
Modern commercial transit and industrial operations face unique mechanical demands depending on their local operating environment. Our product designs are optimized for these diverse challenges, ensuring reliable operation anywhere in the world.
In Northern European and Canadian regions, road-deicing salts accelerate rust. Our hub assemblies feature Geomet surface coatings and low-temperature synthetic greases, preventing corrosion and ensuring smooth rotation down to -40°C.
For operations in South America and Western Australia, heavy dust and shock loads are constant challenges. Our double-row angular contact ball bearings distribute dynamic loads evenly, preventing premature spalling under heavy weights.
Urban delivery fleets experience constant stop-and-go wear that strains chassis mountings. Our optimized suspension bushings absorb high-frequency vibrations, protecting internal wheel bearings from transfer shock and reducing wear.
As logistics and automotive sectors transition to autonomous and software-defined platforms, the humble wheel hub is evolving into a key source of real-time vehicle data.
We are currently developing smart bearing caps equipped with internal temperature and vibration sensors. These transmit real-time telemetry to fleet management software, allowing operators to schedule maintenance before a road failure occurs.
Our research team is testing hybrid carbon-aluminum flanges. These assemblies reduce unsprung weight by up to 25% compared to steel components, helping electric vehicles achieve longer driving ranges.
Looking ahead, we are designing structural wheel hub frames specifically for in-wheel drive motors. This allows system integrators to combine driving, braking, and steering functions into a single modular chassis unit.
Delivering high-quality parts is only half the battle. Our global logistics team ensures that shipments arrive safely and comply with all regional import regulations.
We provide complete PPAP Level 3 documentation, material test reports, and process control plans. This makes it easy for global automotive manufacturers to integrate our components into their assembly lines.
Our engineering department utilizes 3D CAD modeling and finite element analysis (FEA) to design bespoke wheel hubs and suspension components, tailoring dimensions and materials to meet specific client requirements.
Our location in Zhucheng, Shandong, allows us to transport finished products to Qingdao Port within a few hours. This fast transit helps us reduce shipping lead times for our international distributors.
