About the Airtac SC50 Standard Cylinder SC50X450SH
The SC50X450SH is a double-acting pneumatic cylinder delivering 982 N of push force at 0.5 MPa and 1767 N at the maximum operating pressure of 0.9 MPa. Its 20 mm diameter piston rod and 21 mm adjustable air cushion provide reliable deceleration for mid-stroke positioning tasks.
Equipped with a built-in magnet and high-temperature Viton (FKM) seals, this model operates reliably from 0 to +150 °C, making it suitable for autoclaves, foundries, and hot-air handling. The 450 mm stroke falls well within the 1200 mm maximum standard stroke for the 50 mm bore, ensuring ready availability.

Where the Airtac SC50 Standard Cylinder SC50X450SH Is Used
High-Temperature Actuation
With Viton seals rated to 150 °C, this cylinder is ideal for hot stamping presses, autoclave door actuation, and kiln damper controls where standard seals would degrade.
Automated Clamping
Delivers 1374 N of force at 0.7 MPa for consistent clamping in CNC machining fixtures. The built-in magnet allows easy integration of CMSG sensors for clamp confirmation.
Sorting Gate Drive
The 450 mm stroke provides ample travel for diverting packages on high-speed conveyor lines. The adjustable cushioning absorbs impact energy smoothly at the end of each cycle.
Is the Airtac SC50 Standard Cylinder SC50X450SH the Right Cylinder?
Select the SC50X450SH for applications needing a force of roughly 1000 N at standard plant air pressure. If your load requires more, stepping up to the 63 mm bore provides 1559 N of push force at the same 0.5 MPa. For strokes beyond 300 mm, ensure the rod is guided externally if side loads are present, as the 20 mm rod can be subject to bending moments. When replacing, match the 50 mm bore, 450 mm stroke, PT port thread, built-in magnet, and the high-temperature seal specification.
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 SC50X450SH FAQ
At the standard operating pressure of 0.5 MPa, the cylinder produces 982 N extending and 825 N retracting. At the maximum operating pressure of 0.9 MPa, the extending force increases to 1767 N.
No. The AirTAC SC series is a tie-rod cylinder with a shorter body length than an ISO 15552 profile cylinder. It is dimensionally interchangeable only with another AirTAC SC tie-rod cylinder of the same bore, stroke, and mounting configuration.
