The core advantages of aluminum steering shafts compared to steel/iron ones
Ultra-lightweight design
Significantly reduces the unsprung mass, enhancing handling flexibility and response speed.
High strength-to-weight ratio
While maintaining ultra-high performance and safety, achieve a strength-to-weight ratio far exceeding that of steel.
High corrosion resistance
Naturally resistant to rust, with excellent durability. Moreover, the surface treatment process is mature, giving the appearance a more premium feel.
Integrated precision casting
Perfectly integrating complex functional structures with modern industrial aesthetics, the design freedom is much greater than that of traditional stamping and welding components.

Necessity And Core Advantages
Crankcase Of Steering has significant necessity and advantages in the production of heat dissipation parts (such as heat sinks and heat sinks) in many application scenarios：
Pressure relief to prevent leakage
Expel the high-pressure gas that has entered the piston to prevent the crankcase pressure from being too high, which may cause the oil seal and gasket to burst and leak oil.
Maintain the performance of engine oil
Eliminate water vapor and acidic substances in the gas leakage, prevent the emulsification of engine oil and the formation of sludge, and maintain the lubrication efficiency.
Comply with emission regulations
Recover the blow-off gas and burn it in the combustion chamber, reducing the emission of hydrocarbon pollutants by over 60% and meeting the mandatory environmental protection standards.
Prevent serious malfunctions
Avoid sludge clogging the oil passage, acidic corrosion of metal parts, and prevent fatal damages such as engine cylinder pulling and bearing bush melting.
Competitive advantage
The company conducted a competitive advantage analysis to identify its strengths and weaknesses compared to its rivals.
Construction machinery
loaders, excavators, bulldozers and other equipment that require strong driving force and flexible steering.
01
Agricultural machinery
Heavy agricultural machinery such as large tractors and combine harvesters that require frequent steering during field operations.
02
Heavy-duty transport vehicles
mining dump trucks, large forklifts and other vehicles that require high load-bearing and steering capabilities when operating in complex sites.
03
Special vehicles
Airport shuttle buses, large cranes, certain military vehicles and other dedicated vehicles equipped with drive steering axles.
04
Off-road vehicles
On the drive steering axles of some all-terrain vehicles or special off-road vehicles, used to enhance the passability of complex terrains.

FAQ
Q: What is the function of the steering crankcase?
A: Accommodate and protect the steering mechanism (such as gears, racks, and hydraulic valves), transmit the steering wheel torque to the wheels, and at the same time seal the lubricating grease/hydraulic oil.
Q: Which equipment uses a steering crankcase?
A: Mainly applied to: Construction machinery (loaders, excavators Heavy-duty trucks/mining dump trucks Agricultural machinery (tractors, harvesters) Special vehicles (forklifts, airport tractors)
Q: What are the common faults? How to judge?
A: Oil leakage: Aging of the oil seal or cracks in the box (oil stains on the ground); Abnormal noise/jamming: Internal gear wear or insufficient lubrication (heavy steering, abnormal noise); Steering failure: Hydraulic valve blockage or box deformation (immediate repair required).
Q: How to maintain the steering crankcase?
A: Regularly check the oil level and quality (every 500 working hours); Replace the sealing parts (every 2-3 years or when there is oil leakage); Avoid overloading steering to prevent the box from deforming under force.
Q: What are the material requirements for the steering crankcase?
A: Mostly cast steel or high-strength cast iron, and must meet: High rigidity and impact resistance; Corrosion resistance (especially for outdoor operation equipment); Precision processing ensures the accuracy of gear fit.
Q: Can it be replaced or repaired by oneself?
A: Not recommended! Professional equipment is required for disassembly and assembly, pressure testing and calibration.
our certifications
ISO 14001:2015
The ISO 14001:2015 certificate is an internationally recognized document that indicates that an organization has established, implemented, maintained, and continuously improved an environmental management system (EMS) that complies with the requirements of ISO 14001:2015.
This certificate certifies that the environmental management system of this organization has met international standards, enabling it to systematically manage its environmental responsibilities and commit to sustainable development.
IATF16949:2016
IATF 16949:2016 is an international standard for quality management systems in the automotive industry. It was developed by the International Automotive Task Force (IATF) and was released in October 2016, replacing the previous version of ISO/TS 16949:2009.
The core objective of IATF 16949 is to continuously improve, prevent defects, reduce variations and waste in the automotive supply chain. It aims to ensure that the design and manufacturing of automotive products (including components and materials) can always meet customer requirements and even exceed customer expectations.
