  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, autocollimator and other

  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 measure either inside di
