A high-precision ISO-standard pneumatic cylinder featuring corrosion-resistant construction and dual cushioning. The hard-anodized barrel ensures extended service life in humid or mildly corrosive environments. Optimized seal geometry reduces breakaway pressure to 0.03 MPa, enabling precise low-pressure operation.
- Packaging machine ejector mechanisms
- CNC machine tool clamping devices
- Automotive assembly line positioning systems
- Food processing conveyor gate actuators
- High-cycle automation (up to 1.5 million cycles MTBF)
Installation tips:
Align cylinder axis within ±0.2° of load path. For vertical mounting,
use rod-down orientation to prevent condensate accumulation.
Lubricate rod weekly in high-cycle (500+ cph) applications.
- Magnetic sensors: D-A93 series (non-contact reed switch)
- Mounting brackets: STF series for trunnion mounting
- Rod ends: FEM-10M for female threaded connections
