Ultra-slim profile cylinder (25mm height) with integrated stroke adjustment mechanism, designed for precision positioning in space-constrained automation systems. Features dual-position memory function through its screw-type mechanical stopper, allowing micron-level repeatability (±0.1mm). The hardened piston rod (Cr-Mo steel) resists side loads up to 15N·m.
- PCB handling robots in electronics assembly
- Precision glass panel pressing mechanisms
- Pharmaceutical blister packaging machines
- Wafer cassette elevators in semiconductor FABs
- 3D printer automatic bed leveling systems
1. Use M4x8mm screws (max torque 1.2N·m) for flange mounting
2. Maintain 0.5mm clearance between stopper and moving parts
3. Lubricate with ISO VG32 turbine oil if non-lubricated air is used
4. Buffer adjustment: Turn clockwise to soften end impact (1 rotation ≈ 15% damping change)
- Requires 5μm filtered air to prevent cushion valve clogging
- Max lateral misalignment: 0.3mm during mounting
- Not suitable for vertical downward thrust applications without external guides
