Tie Rod Hydraulic Cylinder with Extended Rear Piston Rod

This video demonstrates the assembly and testing of a tie rod hydraulic cylinder with an extended rear piston rod. It starts by fitting a PTFE wear ring and a black seal into the piston groove, adjusted with a screwdriver. After placing an O-ring on the rear square end cap, the barrel is assembled. The sealed piston and rod assembly is aligned and pushed into the barrel, pressed home with a flat plate. A brass guide end cap is slid along the rod and pre-tightened. The upper square end cap is mounted, four tie rods are inserted, and the nuts are hand-threaded before pneumatic tightening. Yellow dust plugs are screwed into the ports. Finally, hydraulic lines are connected, and a tape measure records retracted and extended positions to verify the stroke. This process addresses the challenge of assembling a tie rod hydraulic cylinder with precise sealing and alignment, ensuring even tie rod tension and accurate stroke verification. It is useful for procurement engineers, design teams, and maintenance technicians in automation, molding, and heavy machinery, where reliable rear-rod extension and space-saving installation are required. When sourcing a tie rod hydraulic cylinder, this video serves as both an assembly guide and a quality reference.
