Product Description
The CK45 Hydraulic Piston Rod is one of the key load-bearing components in hydraulic systems, primarily used within hydraulic cylinders to withstand the pressure and mechanical load between the piston and hydraulic oil. It possesses excellent mechanical properties, wear resistance, and corrosion resistance, making it widely applicable in various hydraulic systems, especially suitable for hydraulic equipment in high-load and high-pressure environments.
Manufacturing Process
The manufacturing process of the CK45 hydraulic piston rod includes the following steps:
Raw material processing: Select high-quality CK45 steel and process it into round bars of the required diameter through cold drawing or hot rolling.
Machining: Shape and size the rod using processes such as CNC turning, grinding, and high-precision polishing.
Heat treatment: Perform induction quenching to achieve a hardness of HRC55±2, with a quenching depth selectable between 0.5–3.5mm.
Surface treatment: After hard chrome plating, conduct secondary polishing to ensure a smooth surface with a maximum roughness of Ra 0.2 microns.
Quality Control
1. Material Certification: Ensure the use of genuine CK45 material that meets standards.
2. Hardness Testing: Test the hardness of the substrate and surface coating.
3. Dimensional and Geometric Tolerance Inspection: 100% inspection of diameter, roundness, and straightness.
4. Surface Quality Inspection: Use a roughness tester to check the surface finish and visually inspect the coating for defects.
5. Non-Destructive Testing: Magnetic particle testing can be performed upon customer request to detect surface micro-cracks.
Features
1. High wear resistance: Hard chrome plating significantly increases surface hardness and reduces wear.
2. Corrosion resistance: The chrome layer effectively prevents rust and chemical corrosion.
3. Low friction coefficient: The smooth chrome-plated surface reduces friction and improves mechanical efficiency.
4. High precision: Low surface roughness and high dimensional accuracy ensure smooth movement.
5. Long service life: Fatigue resistance is further enhanced through induction hardening and rolling processes.
Applications
1. Engineering machinery: Excavators, loaders, cranes, etc.
2. Agricultural machinery: Tractors, harvesters, etc.
3. Concrete equipment: Concrete mixers, pump trucks, etc.
4. Mining equipment: Mining trucks, excavators, etc.
5. Industrial equipment: Injection molding machines, textile machinery, conveying machinery, etc.
