High-precision industrial cylinder featuring dual adjustable pneumatic cushions for shock absorption. The anodized aluminum construction provides corrosion resistance, while the chromium-plated piston rod ensures durability in harsh environments. Includes built-in magnet for position sensing compatibility. Requires ISO VG32 or equivalent hydraulic oil lubrication.
- Precision press-fit operations in automotive assembly
- Variable stroke material handling systems
- Packaging machine stopper mechanisms
- Plastic injection molding ejectors
- CNC machine tool clamping devices
Installation note:
Adjust cushion screws while observing actual motion - turn clockwise to increase damping.
Maintain 0.5-1mm clearance between rod end and load during alignment. Lubricate through
air port using 1-2 drops of oil every 50,000 cycles.
Critical parameters:
Max side load 25N, axial misalignment tolerance ±2°. Avoid rapid pressure changes
exceeding 0.3 MPa/sec to prevent seal damage. For vertical mounting, use guided
carriage kits (ASQ12-50 recommended).
