Precision-adjustable pneumatic cylinder featuring micrometer-style stroke adjustment mechanism with ±10mm fine-tuning capability. The dual-cushion design minimizes end-impact noise while maintaining positioning accuracy (±0.5mm repeatability). Hard chromed piston rod resists side-load wear in misalignment scenarios.
- Variable height work platforms in assembly lines
- Clamping force adjustment in CNC fixture systems
- Material handling with variable stacking heights
- Packaging machine pusher mechanisms
- Glass cutting equipment with position compensation
Installation note:
Maintain 0.5mm minimum clearance between cylinder body and machine frame.
Use locknuts (included) to secure adjustment screws after calibration.
Lubricate through air port using ISO VG32 turbine oil monthly.
