Production Application
The hydraulic cylinder rod is a crucial component in a vehicle steering system, with its core function being to transmit force and motion. It can achieve the change of wheel direction in accordance with the movement of the steering cylinder, enabling the driver to overcome steering resistance with relatively small operating force.
The hydraulic steering cylinder typically works in coordination with the steering oil pump and control valve: the oil pump supplies high-pressure oil fluid, the control valve adjusts the oil flow according to the steering wheel's rotation angle, and the steering cylinder is responsible for the final force conversion.
Our products not only provide robust support for the continuous and efficient operation of vehicles but also effectively reduce the frequency of malfunctions, enabling vehicles to consistently perform at their best across various operating scenarios.

Nitriding Shaft / QPQ Rod
What is QPQ?
Quench Polish Quench is a treatment that significantly increases corrosion and wear resistance. lttreats the existing steel with a surface diffusion process at the molecular level. This is donethrough a liquid salt bath process which greatly enhances the durability of the steel.
The QPQ treatment doesn't add any material to the bore but rather treats the bore as it comesfrom the factory, thus maintaining the original bore quality. One big advantage of QPQ is that theprocess treats both the inside and the outside of the barrel.
The QPQ finish is found on our Modern, Performance, and Premium Black Series barrels.
