Precision-engineered adjustable stroke cylinder featuring dual locking nuts for stroke fixation stability. The hardened piston rod (HRC 35-40) resists wear in high-cycle applications. Integrated auto-lubrication design allows maintenance-free operation for 5,000km travel distance under standard conditions.
- Precision position control in semiconductor handling robots
- Variable clamping force adjustment in CNC fixturing
- Packaging line product ejection systems
- Textile machinery thread tension control
- Automated door stroke limitation in cleanrooms
Installation guidance:
For optimal performance, maintain 0.1-0.3mm clearance between stopper nuts.
Apply Loctite 243 on adjustment threads after final positioning. Lubricate with
ISO VG32 hydraulic oil for initial operation. Avoid lateral load exceeding 15N·m.
