  AISI 1045  chrome plated shaft  is cold drawn, precision ground and polished shafting with a seam free surface finish of RMS 25 max. The bars are then hard chrome plated by electrolytically deposited layer of chromium metal on the surface. This hard chromed surface confers the important properties of corrosion resistance and wear resistance; it is also very smooth and therefore has a low coefficient of friction. Not least of all, it has an attractive and durable decorative appearance. Stainless Steel is an iron-based metal alloy, with added elements including chromium, nickel, silicon and carbon. These elements are mixed into the base material itself, and are present throughout the entire structure of the shafts.   The surface of the Stainless Steel is then finely polished to a mirror finish. Because the Stainless properties are evident throughout the entire bar, any damage or scratches can simply be re-polished to expose the fresh new material underneath. As a pro...

  There are many advantages of using  hollow piston rod .On the one hand, it can obviously reduce the weight of the whole structure. On the other hand, it can further improve the use performance of mechanical equipment. In other words, with the emergence and application of hollow piston rod, the equipment has a greater development space in the performance and use. However, to give full play to the use performance of  hollow bar ,first of all, it needs to ensure its straightness. In the process of straightness detection, do you know which methods can be used? Let's get to know the details below! In general, to accurately detect the straightness of the hollow piston rod, four different methods can be selected. The first method is the pitch method. Usually, this method is mainly used for measuring long parts. For example, when the piston rod is divided into several small sections, the relative readings of each segment can be measured with the aid of the level, auto...

  In order to measure and decide which   hydraulic cylinder   you need, first of all you would have to visually determine the type of hydraulic cylinder you try to replace. Here are the the main three types of hydraulic cylinders: Piston rod cylinder  – has piston inside, can be single and double acting (ex. Clevis cylinder) Plunger cylinder – mostly is a single acting cylinder (ex. Snow plow cylinder) Telescopic cylinder – has multiple stages, can be single and double acting Main hydraulic cylinder attributes are as follows: Bore diameter Rod diameter Retracted length Extended length Stroke Mounting ends Hose ports Working pressure Here is a detailed guide on how to properly take measurements of any plunger or piston rod hydraulic cylinder. STEP 1: Piston diameter or inside barrel diameter is the main dimension of the hydraulic cylinder and known in the hydraulic industry as “BORE”. Therefore it has to be measured first. If your cylinder is taken apart, simply measu...

Carbon steel balances durability, hardness, and wear resistance using formability, weldability, and durability; Chrome plating provides corrosion resistance along with an Extremely reflective look High precision tolerances, which ensures when used to make hydraulic piston rod, it can fit the cylinder precisely. Good Hardness: the surface hardness attaining HV850 minimal and upward, which not only help improve wear resistance but also help extend the life span of these chrome plated rods, thereby helping the consumer save the cost. High performance of strength: The yield strength of chrome plated bars can be 75000 psi up to 100000 psi. Besides  chrome plated rods ,  Datong Hydraulic  also produce and supply induction hardened chrome plated cylinder rods. honed tube , hydraulic cylinder barrel ,  hollow chrome bar Want to buy chrome plate rods?

  high tensile 4140 induction hardened chrome bar made from chrome plated steel are typically used in applications where there are heavy duty conditions – often corrosive. The steel contains increased levels of alloying elements which delivers a high grade steel with superior tensile strength exhibiting good machining. 42CrMo4 chrome plated bar is manufactured from low-alloy chromium-molybdenum steel and supported by an induction hardened case offering greater strength and resistance to mechanical damage from external impact. It is used in applications requiring greater yield strength in combination with greater surface impact resistance.

  Cold Drawn Seamless Tubing  (CDS) is a cold drawn steel tube which offers uniform tolerances, enhanced machinability and increased strength and tolerances compared to hot-rolled products. Produced from hot rolled 1026, the cold drawing process increases the tube's physical properties and offers better tolerances and reduced machining allowances over hot finish seamless tube. Cold drawn seamless tube and pipe is produced by piercing hot billets and subsequent rolling which reduces their diameter and elongates them. This material is then passed through a die and over a mandrel plug to produce an accurate size and gauge which is the essence of the cold drawing process.

  Chrome hollow bar   we also call it chrome plated tubing,it is a kind of tube which inner surface is honed and the outer surface is chrome plated. The chrome plated surface provides excellent wear and corrosion resistant performance of the tube. Chrome plated steel tubing has an excellent durability and helps reducing friction. Chrome plated pipe is mostly used as hydraulic piston rods in order to have a lighter hydraulic cylinder. And chrome plated OD tube also can be utilized for applications where precision outside diameter or high smooth outside surface is  required. Chrome plated OD tubes can be supplied with honed inside surface for telescoping hydraulic cylinder applications too. Chrome hollow bar mainly suitable for elevator cylinder, telescope cylinder, scaling ladder, agriculture machines, engineering machinery, construction machinery etc.
