High-precision adjustable stroke cylinder featuring dual-position mechanical stoppers for mid-stroke positioning. The hexagonal adjustment nuts enable micrometer-style stroke calibration (minimum 0.5mm increments). Integrated wear-resistant guide bands ensure smooth operation in high-side-load applications.

Typical Applications:

• Variable height positioning in automated assembly lines
• Press tooling with depth control requirements
• Material handling systems requiring adjustable clamping force
• Packaging machinery with product size variation
• Automated welding jigs with Z-axis adjustment

Installation notes:
1. Align adjustment nuts with locking pliers before air connection
2. Apply anti-seize compound to stopper threads for harsh environments
3. Maximum side load capacity: 120N at mid-stroke
4. Recommended lubrication: ISO VG32 turbine oil (drip feed every 500,000 cycles)

⚠️ Critical parameters:
- Minimum operating pressure for stopper adjustment: 0.3MPa
- Allow 15mm clearance around adjustment nuts for tool access
- Max lateral misalignment: ±1.5° from ideal axis
