High-precision dual rod cylinder designed for applications requiring stroke adjustment and position holding. Features symmetrical force transmission through parallel rods and anti-rotation design for stable linear motion. The hardened piston rods withstand side loads up to 300N at full extension. Requires 1-3 drops of ISO VG32 turbine oil per port weekly for maintenance.
- Precision clamping fixtures in CNC machining centers
- Vertical lifting mechanisms for glass handling robots
- Web tension control in printing/packaging lines
- Position-adjustable stops in automotive assembly jigs
- Synchronized gate operation in material handling systems
Installation note:
Mount using M6x1.0 screws (max 15Nm torque). Maintain 0.5mm alignment tolerance between rod ends and load.
For adjustable stroke applications, lock cushion collars with 2.5Nm torque after position setting.
Critical parameters:
Max side load capacity decreases by 15% per 10℃ above 50℃.
Not recommended for vacuum applications without rod seal modification.
