Precision-engineered adjustable stroke cylinder featuring micrometer-style stroke adjustment mechanism (±2mm repeatability). The unique twin-lock design maintains stroke setting stability under vibration. Integrated magnetic piston enables position feedback when used with sensors (not included).

Industrial Applications:

• Variable height work platforms in assembly lines
• Material handling with programmable stop positions
• Packaging machines requiring stroke adjustments between product changes
• Plastic injection molding ejector systems
• Test equipment with position calibration requirements

Installation recommendation: For optimal performance, install with 0.5-1mm alignment tolerance and use SMC-style floating joints. Lubricate with ISO VG32 turbine oil if operating below -5℃. Maximum side load capacity: 15N at mid-stroke.

Adjustment Procedure:

1. Loosen both lock nuts using 8mm wrench
2. Rotate adjustment dial (1 full rotation = 2mm stroke change)
3. Re-tighten lock nuts to 1.2-1.5N·m torque
4. Perform 3-5 test cycles to verify stability
