Chrome Plate Rod for hydraulic cylinder is an important component for mechanical piston movement. How to select high-quality chrome plated rod is very important. We will introduce the selection criteria from the aspects of material, hardness, straightness, and thickness of chrome-plated layer.
What is the key quality requirements of chrome plated cylinder piston rods?
Due to the high frequency of piston movement, the quality requirements for this part are very high. After the piston rod is chrome-plated, its hardness and service life can be improved. Let me briefly introduce the basic requirements of the chrome plated rod for hydraulic pistons.
Basic requirements for chrome plated rods for cylinder piston:
1. Must have sufficient strength, stiffness and stability;
2. Good wear resistance, high machining accuracy and surface roughness requirements;
3. Structurally, minimize the influence of stress concentration;
4. Make sure the connection is firm and prevent loosening;
5. The design of the hydraulic piston rod structure should facilitate the disassembly and assembly of the piston.
How to choose a high-quality chrome plated piston rod?
1. Materials
This material is the main raw material for manufacturing hydraulic cylinder barrels and cylinder piston rods, so we can choose high quality chrome-plated piston rods according to the quality of the materials used. We produce high quality material CK 45 chrome plated rods, SAE 1045 chrome plated rods and SAE 4140 chrome plated bar.
2. Hardness
Hardness mainly refers to the ability of a material to resist the pressing of hard objects into its surface. However, the hardness is not as hard as possible, the hardness should be appropriate. Because only the proper hardness can guarantee the quality of the product. To provide higher hardness, we produce and supply induction hardened chrome plated rods.
3. Straightness
High-quality chrome-plated piston rods also attach great importance to their straightness requirements, because straightness is an important indicator.
4. Thickness of chrome-plated layer
A good chrome rod will usually have a chrome finish of 0.22mm or more, as this thickness works well for a smooth shaft piston rod.
Chrome-plated piston rods are mainly used in hydraulic pneumatics, construction machinery, automobile manufacturing piston rods, guide columns for plastic machinery, packaging machinery, printing machinery cylinders, textile machinery. And it can aslo be used as linear shaft for many machines, such as conveying machinery shafts, linear optical shafts, etc, so chrome plated rods are known as hard chrome plated shafts also.
We specialize in producing various specifications and models of chrome-plated rods, piston rods, hollow piston rods, chrome-plated piston rods, hydraulic cylinder rods, precision piston rods, oil cylinder piston rods, smooth shafts, linear shafts, etc.
Our products have good surface finish, uniform hardness, stable delivery, direct supply from the factory, a large number of spot, wholesale prices, and fast delivery. Customers are welcome to contact us for more details.
