About the Airtac SC50 Standard Cylinder SC50X40H
The AirTAC SC50X40H is a double-acting tie-rod cylinder with a 50 mm bore and 40 mm stroke, factory-equipped with Viton (FKM) seals for reliable operation in high-temperature environments up to 150 °C. It delivers 982 N of push force at 0.5 MPa and 1767 N at the maximum operating pressure of 0.9 MPa, driven by a 20 mm diameter piston rod.
With a compact body length A of 150 mm and an adjustable air cushion of 21 mm, this cylinder decelerates end-of-stroke loads effectively without adding external shock absorbers. The PT1/4 port and M16x1.5 rod thread make it a direct fit for standard pneumatic circuits, while the tie-rod construction allows easy maintenance and seal replacement.

Where the Airtac SC50 Standard Cylinder SC50X40H Is Used
High-Temperature Actuation
The Viton seals allow this SC50X40H to operate continuously in ambient temperatures up to 150 °C, making it suitable for autoclave door mechanisms, foundry equipment, and drying ovens where standard seals would degrade.
Short-Stroke Clamping
With a 40 mm stroke and 982 N of force at 0.5 MPa, this cylinder excels in compact clamping and pressing fixtures on assembly lines, providing a rigid hold without excessive cycle time.
Sterilization & Clean Processes
Viton's chemical resistance suits this cylinder for washdown-adjacent or chemically aggressive environments in pharmaceutical and food processing plants, where NBR or TPU seals would swell or crack.
Is the Airtac SC50 Standard Cylinder SC50X40H the Right Cylinder?
Choose the SC50 bore when your application needs roughly 1000 N of force at standard plant pressure; if you require more force, step up to the SC63 which provides 1559 N at 0.5 MPa, or down to the SC40 at 628 N for lighter, faster cycles. The 40 mm stroke is well within the 1200 mm maximum standard stroke for this bore, keeping lead times short.
For a direct replacement, match five points: 50 mm bore, 40 mm stroke, PT1/4 port thread, basic mount (no factory bracket), and the Viton seal designation (H). This cylinder is not dimensionally interchangeable with ISO 15552 profiles—it is a tie-rod design and must replace another AirTAC SC or equivalent tie-rod cylinder.
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 SC50X40H FAQ
At 0.7 MPa (7 bar), the SC50 bore generates 1374 N of push force and 825 N of pull force. The maximum operating force at 0.9 MPa is 1767 N push, and the theoretical maximum at 1.0 MPa is 200 kgf.
No. The AirTAC SC series is a tie-rod cylinder, not an ISO 15552 profile cylinder. Its body length (A=150 mm) is shorter than an equivalent ISO 15552 unit, so mounting dimensions and end-cap profiles differ. Only replace another AirTAC SC or a mechanically identical tie-rod cylinder with matching bore, stroke, port, and mount.
