1. Reduce weight: Since the middle of the piston rod is hollow, the hollow piston rod is lighter in weight than a solid piston rod. This reduces the load on the entire system and improves mechanical efficiency.
2. Increased Rigidity: Although hollow piston rods are lighter in weight, they provide greater rigidity due to their structurally stronger design. This helps reduce vibration and deformation, improving system stability and accuracy.
3. Improve heat dissipation performance: The hollow piston rod can conduct and dissipate heat better. Since the piston rod generates heat during movement, the hollow design can increase the surface area and improve the heat dissipation effect, thereby reducing temperature and thermal stress.
4. Improve lubrication effect: The cavity inside the hollow piston rod can be used as a channel for lubricating oil. This effectively delivers lubricant to all parts of the piston rod, reducing wear and friction and extending service life.
5. Convenient installation and maintenance: The design of the hollow piston rod makes it easier to install and disassemble. Due to its lighter weight, it is more convenient to operate. In addition, the hollow piston rod structure makes maintenance and inspection easier.
