Direct from our state-of-the-art factories. High-precision bearing assemblies designed to support maximum radial loads and critical axial forces.
Modern transit, logistics, and heavy-duty agricultural operations demand high-integrity mechanical components. The global demand for axle hub assemblies and heavy-duty bearing components is dictated by rising operational payloads, extreme environment cycles, and strict zero-failure engineering metrics. As an essential link in vehicular and industrial drivetrains, the hub unit manages static weight, rotational friction, and dynamic lateral stresses.
JITO Bearing address these demands by supplying comprehensive metallurgical designs configured to eliminate micro-cracking, friction-based power losses, and moisture contamination. Our technical methodologies optimize structural grain flow, utilizing ultra-pure chrome steel (GCr15) that has undergone multi-phase induction hardening. This ensures our wholesale partners receive high-durability products that maintain precision under sustained high-speed operations.
Established in 2006, JITO Bearing operates as a modern scientific and technological enterprise integrating research and development, precision production, and global trade operations. We are proud members of the China Association of Automobile Manufacturers and the China Bearing Industry Association. Furthermore, we are recognized as a National High-Tech Enterprise, a National Standard Drafting and Formulation Unit, and a Specialized, Refined, Distinctive, and Innovative Enterprise in Hebei Province.
Under the leadership of General Manager Shizhen Wu—who serves as a standing committee member of the Political Consultative Conference of Guantao County—JITO focuses on high-precision bearings with noise-level ratings down to Z1V1/Z2V2/Z3V3 and geometric tolerances meeting P0/P6/P5 standards. Our industrial footprint covers over 30,000 square meters, featuring state-of-the-art production lines designed for international delivery.
Specialized processing locations ensuring continuous workflow from raw forging stages down to micrometric assembly.
JITO maintains two distinct industrial factories covering a combined construction layout of more than 30,000 square meters. The first factory focuses on rough processing, hot metal forged structures, and advanced heat treatment lines. The second handles precision grinding, high-tolerance assembly, quality assurance inspection, and global shipment packaging.
Every step of the process—from the delivery of premium GCr15 chrome steel, rough turning, automated heat treatments, to the final micro-fine groove grinding—is meticulously controlled. Our components are widely trusted and integrated into passenger cars, buses, heavy transport trucks, material handling forklifts, agricultural machinery, papermaking systems, power generation wind turbines, and metallurgical mills.
Achieving zero-defect products through precise structural testing and testing simulators.
We feature coordinate-measuring machines (CMM), spectroscopic analyzers for steel batches, length-measuring instrumentation, and specialized roundness meters. This allows JITO components to reach P0, P6, and P5 limits with ease.
Our research facility features simulated hub fatigue testing apparatuses and environmental mud testers, proving hub life and sealing under harsh agricultural and mining conditions before batch shipping.
We filter dynamic rotational interference via Z1V1, Z2V2, and Z3V3 vibration chambers. This ensures smooth operations, lowers overall friction torque, and avoids temperature spikes in high-RPM operations.
JITO Hub Assemblies and Bearings are deployed across critical global sectors to optimize performance under heavy mechanical demands.
Our heavy-duty hub assemblies and self-aligning bearings resist exposure to dirt, soil, water, and fertilizers, keeping farm machinery operating smoothly during critical harvest cycles.
Designed for prolonged highway speeds under maximum payload constraints. Features custom oil seals and heat-treated structures to prevent axle failure.
Built for extreme environments. Our cylindrical roller bearings handle massive radial forces and dynamic shocks in conveyor units and heavy crushing mills.
JITO distributes high-precision bearings and hub assemblies to 30 countries and regions worldwide, including the European Union, South America, North America, Southeast Asia, and the Middle East. To provide outstanding services to our business partners and clients, we established Liaocheng Jingnai Machinery Parts Co., Ltd in Liaocheng City, Shandong Province. This location is situated only 15 minutes from the Liaocheng high-speed railway station and 1 hour from Jinan Yaoqiang International Airport, providing convenient logistics connectivity.
To support global supply chains, JITO registers its trademarks globally, including in the EU and under Madrid agreements. We participate in major automotive and industrial trade exhibitions, including the Shanghai International Bearing Professional Exhibition, the Canton Fair, the Beijing International Automobile Exhibition, and Frankfurt Automechanika.
Approved under international automotive standards, ensuring high performance in every batch.
Quality reliability is core to JITO operations. Our facilities adhere strictly to ISO 9001:2015, IATF 16949:2016 (Automotive Quality Management Standards), and ISO 14001 Environmental Management systems. Our production processes feature automatic sorting, micro-honing, dynamic balancing, and double-lip seal pressing to eliminate defect rates.
