Precision-adjustable cylinder featuring a unique mechanical locking mechanism for mid-stroke positioning. The graduated scale (±75mm range) enables micron-level adjustments via the threaded end cap. Corrosion-resistant construction with integrated shock absorbers prevents seal degradation in high-cycle applications (up to 1.5 million cycles at 0.5MPa). Requires 5-40μm filtered air with ISO VG32 lubricant.
- Variable clamping force fixtures in CNC machining
- Adjustable press mechanisms for plastic molding
- Position-staggered material handling systems
- Precision alignment in semiconductor wafer stages
- Tension control for winding/unwinding machines
Installation protocol:
Locking nut requires 18-22N·m torque during stroke adjustment.
Maintain 0.5mm minimum parallel alignment tolerance between rod and load.
For vertical mounting, install rod-down orientation to prevent seal wear.
