About the Airtac SC32 Standard Cylinder SC32X550SH
The AirTAC SC32X550SH is a double-acting tie-rod cylinder with a 32 mm bore and a non-standard 550 mm stroke, built for hot environments with Viton (FKM) seals that shift the operating range to 0–150 °C. Its 12 mm piston rod delivers 724 N of push force at the maximum 0.9 MPa operating pressure, and the adjustable air cushion (21 mm length) decelerates the piston quietly at end-of-travel.
A built-in magnet (-S suffix) lets you clamp CMSG, DMSG, or EMSG reed/solid-state sensors directly onto the tie-rod barrel for rod-position feedback. The compact body (A=140 mm) plus stroke gives an extended length of approximately 690 mm, making it a space-efficient choice for high-temperature automation tasks that need sensor confirmation.

Where the Airtac SC32 Standard Cylinder SC32X550SH Is Used
High-Temperature Actuation
Viton seals handle 0–150 °C, making this cylinder suitable for autoclave door mechanisms, drying ovens, or foundry knock-out stations where standard seals would degrade.
Sensor-Confirmed Clamping
The built-in magnet allows CMSG/DMSG sensors to verify rod position in automated welding fixtures or hot-melt glue dispensing, ensuring the clamp is fully engaged before the cycle starts.
Light Part Sorting
With 724 N push force at 0.9 MPa, it diverts small hot parts on a conveyor. The 550 mm stroke reaches across a wide belt, and the air cushion protects the actuator at high cycling speeds.
Is the Airtac SC32 Standard Cylinder SC32X550SH the Right Cylinder?
Choose the SC32 when 402 N push at 0.5 MPa is sufficient; if you need more force, step up to the SC40 (628 N at 0.5 MPa) or SC50 (982 N at 0.5 MPa). This 550 mm stroke exceeds the bore’s 1000 mm maximum standard limit, so it is a made-to-order item—confirm lead time. For strokes over 300 mm, side loads can bend the 12 mm rod; use an external linear guide or switch to a guided cylinder if the load is not perfectly axial. When replacing, match bore (32), stroke (550), PT1/8 port thread, the built-in magnet (-S), and the Viton seal (H) to keep the same sensor and thermal capability.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SC32 Standard Cylinder SC32X550SH FAQ
At 0.5 MPa it delivers 402 N pushing and 345 N pulling. At the maximum operating pressure of 0.9 MPa, the push force rises to 724 N. The theoretical maximum at 1.0 MPa is 82 kgf.
No. The SC32X550SH is a double-acting cylinder and does not lock or hold position when pressure is exhausted or the directional valve is centered—the piston will drift. For load holding, you must add an external rod brake, a mechanical lock, or a pilot-operated check valve.
