About the Airtac SC50 Standard Cylinder SC50X200H
The SC50X200H is a double-acting pneumatic cylinder with a 50 mm bore and 200 mm stroke, built on AirTAC's compact tie-rod SC platform. Its Viton (FKM) seals shift the operating temperature range to 0–150 °C, making it suitable for hot environments where standard TPU seals would degrade. At 0.5 MPa it delivers 982 N pushing force and 825 N pulling force, rising to 1767 N push at the 0.9 MPa maximum operating pressure.
This model uses a 20 mm diameter piston rod with M16x1.5 male threads and PT1/4 ports. The adjustable air cushion at each end (21 mm cushion length) decelerates the piston smoothly, reducing end-of-stroke impact. The body length A is 150 mm, giving a total extended length of approximately 350 mm. As a tie-rod cylinder it is shorter than an equivalent ISO 15552 profile cylinder and is not dimensionally interchangeable with that standard.

Where the Airtac SC50 Standard Cylinder SC50X200H Is Used
High-Temperature Automation
Viton seals allow the SC50X200H to operate continuously in ambient temperatures up to 150 °C, making it ideal for actuators near ovens, autoclaves, foundry equipment, or steam lines where standard cylinders would fail.
Clamping & Pressing
With 1767 N of force available at 0.9 MPa, this cylinder suits medium-duty clamping, pressing, and holding fixtures in hot manufacturing cells. The 20 mm rod resists bending under axial loads.
Hot-Material Diverter Gates
The 200 mm stroke and 0–150 °C rating make this cylinder a reliable choice for actuating diverter gates or flippers on conveyors handling hot materials in food processing or industrial drying lines.
Is the Airtac SC50 Standard Cylinder SC50X200H the Right Cylinder?
Choose the SC50X200H when a 50 mm bore provides sufficient force and the application involves elevated ambient temperatures up to 150 °C. If more force is needed, stepping up to the 63 mm bore (SC63 series) raises the push force to 1559 N at 0.5 MPa. For lower force requirements, the 40 mm bore (SC40) delivers 628 N at the same pressure.
This is a basic-configuration cylinder with no built-in magnet and no mounting accessories—order mounting brackets separately if needed (e.g. LB foot mount F-SC50LB, or FA/FB flange). For a direct replacement, match five points: 50 mm bore, 200 mm stroke, PT1/4 port thread, basic mount (no accessory), and no magnet. The 200 mm stroke is well within the 1200 mm maximum standard stroke for bore 50, so this is a standard-stroke model.
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 SC50X200H FAQ
At 0.5 MPa the cylinder produces 982 N extending (push) and 825 N retracting (pull). At 0.7 MPa these rise to 1374 N push and 1155 N pull. The maximum operating pressure of 1.0 MPa yields approximately 1964 N push. All figures assume a clean, filtered air supply at 40 µm.
No. The AirTAC SC series is a tie-rod cylinder with a shorter overall body length than an ISO 15552 profile cylinder, so mounting dimensions and end-cap patterns differ. It is a direct replacement only for another AirTAC SC tie-rod cylinder matching the same 50 mm bore, 200 mm stroke, PT1/4 ports, basic mount, and no magnet.
