Hot rolled pulleys are primarily manufactured using the hot rolling process. This equipment is a replacement product of cast pulleys and double spoke plate pulleys. Hot rolled pulleys are not only light in weight and good in quality, but also have high hardness and wear resistance. They also look more concise and beautiful, about 40% lighter than cast slide pulleys of the same specification.

There are several requirements to pay attention to during the daily maintenance of hot-rolled pulleys:

The piston rod is processed by rolling, which enhances the corrosion resistance of the surface and delays the generation or expansion of fatigue cracks, thereby enhancing the fatigue strength of the cylinder rod. Through rolling forming, a cold work hardening layer is formed on the rolling surface, reducing the elastic and plastic deformation of the contact surface of the grinding pair, thereby enhancing the wear resistance of the surface of the cylinder rod, while avoiding burns caused by grinding.

Introduce methods to enhance the corrosion resistance of the piston rod surface.

Piston rods can be used in hydraulic and pneumatic systems, and their processing requirements are relatively high. Therefore, the quality of hydraulic cylinders is mostly affected by the quality of the piston rods.
