About the Airtac SC50 Standard Cylinder SC50X250SH
The AirTAC SC50X250SH is a double-acting tie-rod cylinder delivering 982 N of push force at 0.5 MPa and 1767 N at the maximum operating pressure of 0.9 MPa. Its 250 mm stroke is well within the 1200 mm maximum standard stroke for the 50 mm bore, making it a reliable mid-stroke actuator for clamping, pressing, and material handling.
This model includes a built-in magnet (-S suffix) for direct mounting of CMSG, DMSG, or EMSG sensors, and features high-temperature Viton (FKM) seals (-H suffix) rated for continuous operation from 0 to +150 °C. The 20 mm diameter piston rod and PT1/4 port thread ensure robust, high-cycle performance in hot or demanding environments.

Where the Airtac SC50 Standard Cylinder SC50X250SH Is Used
High-Temperature Clamping
Viton seals allow this cylinder to operate reliably in ovens, autoclaves, and foundry equipment where ambient temperatures reach 150°C, providing consistent 982 N clamping force at 0.5 MPa.
Automated Pressing
The 250 mm stroke and 1767 N max force suit medium-duty pressing stations. The built-in magnet enables end-of-stroke sensing for precise cycle control in automated assembly cells.
Hot Part Ejection
Ideal for ejecting hot-formed parts from molds or conveyor lines. The sensor-ready design confirms full retraction before the next cycle, preventing jams in high-temperature material handling.
Is the Airtac SC50 Standard Cylinder SC50X250SH the Right Cylinder?
For applications needing more force, stepping up to the 63 mm bore provides 1559 N at 0.5 MPa. If a shorter, more compact cylinder is sufficient, the 40 mm bore delivers 628 N. This 250 mm stroke model uses a 20 mm rod; for strokes over 300 mm or any side-loaded application, always use an external guide or linear rail to protect the rod bearing from bending stress. To replace an existing cylinder, match the 50 mm bore, 250 mm stroke, PT port thread, built-in magnet, and basic mounting configuration.
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 SC50 Standard Cylinder SC50X250SH FAQ
At 0.5 MPa (73 psi) air pressure, the cylinder pushes with 982 N and pulls with 825 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 1767 N. The theoretical maximum at 1.0 MPa is 200 kgf.
Yes, provided the existing unit matches the 50 mm bore, 250 mm stroke, PT1/4 ports, and has a built-in magnet for sensors. The Viton seals are essential for continuous operation up to 150°C; do not use a standard TPU-sealed cylinder as a drop-in replacement for high-heat applications.
