When we have come to understand Hydraulic cylinder After acquiring theoretical knowledge, we often believe ourselves to be capable of anything and expect no difficulties when using hydraulic cylinders; we feel confident in tackling any issue. However, in actual practice, various problems inevitably arise that prove difficult—if not impossible—to resolve. Next, let’s discuss this further. Hydraulic cylinder Potential issues that may arise in practical applications.

　　If you’re asked to take on the R&D project for a piece of equipment, do you already have a clear implementation plan in mind—such as how to select the hydraulic cylinders for this device and what specifications they should meet? This equipment’s… Hydraulic cylinder Precautions.

　　I. How to install and secure a hydraulic cylinder?

　　Common Hydraulic cylinder There are two methods of fixation:

　　1. The first type is a square hydraulic cylinder fixed to Plate B, which must be positioned on Plate B using a keyway.

　　2. The second type is a circular hydraulic cylinder mounted on the ejector plate. It should be noted that an ejector‑plate locking screw must be installed adjacent to the hydraulic cylinder. This location is subjected to significant forces, so it must be secured to prevent deformation.

　　3. Additionally, the hydraulic cylinders are marked with their dimensions, shape, quantity, brand, and stroke length to facilitate verification.

　　II. How should the connection between the hydraulic cylinder and the formwork be designed?

　　The hydraulic cylinder is connected to the formwork via a circular T‑block, and the formwork is designed with a U‑shaped groove to facilitate fabrication and installation. The mating surface dimensions are 8–12 mm, while other areas are kept clear of 0.5 mm tolerances. The hydraulic cylinder connector features an internal screw, and two thread types are available: external threads for internal threads, allowing direct tightening of the screw behind the T‑block.

　　Note: Hydraulic cylinder The dimensions and pitch of the new head shall be based on the 2D specifications provided by the hydraulic cylinder manufacturer; in particular, errors are likely to occur if the pitch is not verified against the specifications.

　　III. Hydraulic cylinder How should the fittings be installed, and how should the air hoses be routed?

　　Hydraulic cylinder fittings come in two types: internal threads and external threads. Internal threads are directly threaded onto the back of the T‑block, while external threads require tapping.

　　That’s not the main point of discussion. The T‑block is round, so it’s hard to grip. It requires cutting two flat surfaces to turn the screw. I’ve never done any metalworking before and often miss the mark with my designs.

　　IV. How to Stop Hydraulic cylinder The rotation?

　　Why does the hydraulic cylinder need to stop rotating? This way, we can understand that the moving piston inside the hydraulic cylinder does not actually come to a complete stop; during repeated overspeed operation, it may rotate, leading to loosening of screws and posing a safety hazard. Therefore, a design that prevents rotation becomes essential.

　　There are typically two design approaches:

　　1. Make a non-rotating washer.

　　2. Fasten a headless screw
