About the Airtac SC50 Standard Cylinder SC50X35H
The SC50X35H is a compact-stroke double-acting pneumatic cylinder from the AirTAC SC tie-rod series, factory-equipped with high-temperature Viton (FKM) seals. With a 50 mm bore and 20 mm piston rod, it generates 982 N of push force at 0.5 MPa, making it a capable actuator for short-throw clamping, ejecting, or pressing tasks in hot environments up to 150°C.
This model has a 35 mm standard stroke and a body length A of 150 mm, giving a total extended length of approximately 185 mm. The adjustable air cushion (21 mm length) decelerates the piston smoothly at end-of-stroke, while the M16x1.5 rod thread and PT1/4 port provide standard connectivity for tooling and pneumatic lines.

Where the Airtac SC50 Standard Cylinder SC50X35H Is Used
Hot-Process Clamping
Viton seals allow the SC50X35H to clamp workpieces inside ovens, autoclaves, or heated presses where ambient temperatures reach 150°C, providing 982 N of holding force at 0.5 MPa.
Short-Stroke Ejection
The 35 mm stroke is ideal for ejecting small parts from hot moulds or dies. The 20 mm rod and adjustable cushion ensure clean, repeatable part separation without impact damage.
Sterilisation Actuation
Suitable for actuating valves or gates in clean-in-place (CIP) or steam-sterilisation equipment, where the FKM seals resist aggressive cleaning chemicals and high-temperature steam cycles.
Is the Airtac SC50 Standard Cylinder SC50X35H the Right Cylinder?
Choose the SC50X35H when your application needs a short, high-force stroke in elevated temperatures where standard TPU seals would degrade. If 982 N at 0.5 MPa is insufficient, stepping up to the 63 mm bore (SC63 series) raises push force to 1559 N at the same pressure; if the force is adequate but you need a longer stroke, the SC50 bore supports standard strokes up to 1200 mm.
For replacement, match these five points: 50 mm bore, 35 mm stroke, PT1/4 port thread, basic (no accessory) mounting, and the -H Viton seal suffix. The SC 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 SC50X35H FAQ
At 0.7 MPa operating pressure, the SC50X35H double-acting cylinder produces 1374 N of push force on extension and 825 N of pull force on retraction. The maximum operating force at 0.9 MPa is 1767 N push.
No. The AirTAC SC series is a tie-rod cylinder with a shorter body length than an ISO 15552 profile cylinder, so mounting dimensions and tie-rod spacing differ. It directly replaces another AirTAC SC50 cylinder with matching bore, stroke, PT port, and Viton seals.
