A high-rigidity compact cylinder featuring integrated buffer tuning and anti-rotation mechanism. The dual-chamber design minimizes internal leakage (<0.3 mL/min at 0.5MPa). The hardened piston rod surface (HRC 45-50) resists side loads up to 120N. Compatible with AirTAC's full range of magnetic switches (D-A93/D-Z73 series).
- Cartesian robot Z-axis actuation
- CNC machine tool clamping mechanisms
- Pharmaceutical blister packaging machines
- Electronics assembly press-fit operations
- Food processing conveyor gate controls
Installation guidelines:
Maintain 0.05mm maximum misalignment during mounting. For vertical installations exceeding 45° angle,
use counterbalance valves. Lubricate every 3,000km stroke distance using ISO VG32 hydraulic oil.
