About the Airtac SC50 Standard Cylinder SC50X260SH
The AirTAC SC50X260SH is a double-acting pneumatic cylinder delivering 982 N of push force at 0.5 MPa and up to 1767 N at the maximum operating pressure of 0.9 MPa. With a 50 mm bore and a 260 mm stroke, this model is well-suited for medium-duty clamping, pressing, and sorting tasks that require a robust push force in a compact footprint.
This specific variant features a built-in magnet (denoted by the 'S' suffix) for direct mounting of CMSG, DMSG, or EMSG sensors, enabling precise end-of-stroke detection. The 'H' suffix indicates a Viton (FKM) seal package, which shifts the operating temperature range from the standard -20 to +70 °C up to 0 to +150 °C, making it a reliable choice for hot or aggressive industrial environments.

Where the Airtac SC50 Standard Cylinder SC50X260SH Is Used
High-Temperature Actuation
The Viton seals allow this cylinder to operate reliably in ambient temperatures up to 150 °C, making it ideal for actuating dampers, diverters, or clamps near ovens, autoclaves, and foundry equipment.
Sensor-Controlled Pressing
With the built-in magnet, CMSG/DMSG sensors can be clamped to the tie-rods to confirm full extension and retraction, enabling closed-loop control for assembly presses and riveting stations.
Sorting Gate Actuator
The 1767 N of force at 0.9 MPa provides ample power to divert heavy packages on a conveyor line, while the 260 mm stroke offers the reach needed for wide sortation lanes.
Is the Airtac SC50 Standard Cylinder SC50X260SH the Right Cylinder?
For applications requiring slightly less force, the 40 mm bore SC40 series provides 879 N of push force at 0.7 MPa. If higher force is needed, stepping up to the 63 mm bore SC63 series offers 2182 N at the same pressure. With a 260 mm stroke, ensure the load is guided to prevent side-loading on the 20 mm diameter piston rod, which can cause premature bearing wear and seal failure.
To ensure a correct replacement, match five key specifications: the 50 mm bore, the 260 mm stroke, the PT port thread, the Viton (FKM) seal material, and the built-in magnet for sensor compatibility. This is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders.
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 SC50X260SH FAQ
At the standard operating pressure of 0.7 MPa, the push force is 1374 N and the pull force is 1155 N (calculated from the 825 N pull force at 0.5 MPa). The maximum push force at 1.0 MPa is 200 kgf.
No. The SC50X260SH is a double-acting cylinder and will not hold its position if air pressure is exhausted or lost. The piston will drift or the load will drop. For load-holding applications, you must use an external rod lock, a pilot-operated check valve, or a mechanical brake.
