3-ton hydraulic bottle jack 3D model plays a pivotal role in engineering and mechanical education: it can be disassembled to illustrate the structural design of core hydraulic components such as the manual pump, oil cylinder, check valve, and relief valve, including their bases, cylinders, and piston rods. It is also ideal for teaching practical engineering concepts like stress analysis, material selection, and seal design (e.g., dust seals and O-rings).
