The steering rack is a core component of a vehicle's steering system. Leveraging over a decade of automotive parts manufacturing expertise, it accurately converts the steering wheel's rotational motion into linear motion to control wheel direction—ensuring stable vehicle maneuvering.
Our steering racks undergo 12+ rigorous performance tests (including durability and corrosion resistance) and feature a max rack thrust of 26,000N and a max travel of 180mm, guaranteeing long-term reliable operation. Compatible with manual, hydraulic power, and electric power steering systems, they meet OEM-level quality standards, making them a trusted choice for precise and safe steering.
With over 15 years of experience in automotive steering system production, our steering rack is crafted via CNC precision machining (tolerance ≤ 0.02mm). This ensures the core component accurately converts rotational motion to linear motion, reducing steering backlash by 30% compared to industry averages—laying a solid foundation for stable, responsive automotive steering performance.
Every steering rack undergoes 16+ authoritative tests, including 5,000-hour continuous operation testing, -40℃ to 120℃ extreme temperature resistance testing, and 500-hour salt spray corrosion testing. Only products with a 100% pass rate leave the factory. This strict quality control helps our heavy-duty steering rack achieve a service life of up to 300,000 km, far exceeding the industry’s 200,000 km average.
Equipped with a high-strength alloy piston, our steering rack delivers a maximum rack thrust of 28,000N—capable of handling heavy loads without deformation. Its optimized 180mm max travel ensures smooth wheel angle adjustment, reducing steering effort by 25% for drivers. These parameters make it ideal for enhancing reliable steering system operation in various driving scenarios.
Our steering rack is fully compatible with manual steering (MS), hydraulic power steering (HPS), and electric power steering (EPS) systems. It features a universal mounting design that fits 90% of mainstream vehicle steering setups, eliminating the need for custom modifications. This versatility makes it a cost-effective choice for customers seeking versatile steering rack solutions.
Adhering to ISO 9001:2015 and IATF 16949 standards, our steering rack meets OEM-level quality requirements—with key components (e.g., seals, bearings) sourced from Tier 1 suppliers. It has obtained ECE R138 certification (a global standard for steering systems), ensuring compliance with regulations in Europe, North America, and Asia. This certification further validates the reliability of our high-performance steering rack.

Here are specific application scenarios of steering rack:
Suitable for daily urban commuting vehicles. Facing frequent starts, stops, and steering operations, its steering backlash of ≤ 0.5mm ensures precise control and reduces steering wheel wobble. Tested, it can operate stably for over 300,000 km under urban road conditions with an average daily travel of 50 km, meeting the reliability requirements of ordinary users for steering rack during long-term commuting.
Targeting the high-frequency and heavy-load needs of freight and logistics vehicles, the maximum rack thrust of 28,000N can easily handle steering under full load. Equipped with an anti-corrosion coating, it still maintains good performance in dusty and humid freight environments, reducing the maintenance frequency of heavy-duty steering rack and facilitating efficient operation of logistics transportation.
Applicable to driving scenarios on complex terrains. With wide temperature adaptability of -40℃ ~ 120℃ and vibration resistance of 10-2000 Hz, it can cope with muddy and bumpy road conditions. Tested, the steering response delay is less than 0.3 seconds when driving on unpaved roads, providing stable support for the automotive steering system.
Matching the high-intensity usage characteristics of public transportation vehicles such as buses, the steering rack that has passed 5,000 hours of continuous operation testing can withstand continuous work of more than 12 hours per day, with a failure rate of less than 0.5%, ensuring the safety and on-time operation of public transportation.
1.Before installation, confirm that the steering rack model is compatible with the vehicle's steering system. Check the integrity of components in accordance with the ISO 8767 standard to avoid installation deviations.
2.During installation, use a torque wrench to fasten the connecting parts according to the specified torque (25-35 N·m) to prevent loosening from affecting steering precision.
3.Before first use, bleed the air from the steering system and add suitable hydraulic oil (for hydraulic types) to ensure no abnormal noise during operation.
4.During daily use, if increased steering resistance or a backlash exceeding 0.5mm is detected, check in a timely manner to ensure the safe operation of the automotive steering system.
