About the Airtac SC50 Standard Cylinder SC50X110H
The SC50X110H is a 50 mm bore double-acting tie-rod cylinder with a 110 mm stroke, factory-equipped with Viton (FKM) seals for reliable operation in ambient temperatures from 0 to +150 °C. It delivers 982 N of push force at 0.5 MPa and up to 1767 N at the maximum operating pressure of 0.9 MPa, driven by a 20 mm diameter piston rod with M16x1.5 male threads.
With a body length A of 150 mm and a 21 mm adjustable air cushion at each end, this cylinder decelerates the piston smoothly to reduce end-of-stroke impact. The PT1/4 port and standard PT thread connections simplify pneumatic plumbing, while the tie-rod construction keeps the overall envelope shorter than an equivalent ISO 15552 profile cylinder.

Where the Airtac SC50 Standard Cylinder SC50X110H Is Used
Hot-Zone Actuation
The Viton seals permit direct installation in autoclave doors, drying ovens, or sterilisation equipment where ambient temperatures reach 150 °C, maintaining consistent 982 N push force.
Heated Press & Forming
Applies 1767 N of closing force at 0.9 MPa for hot-stamping, laminating, or thermoforming tools, with the 21 mm air cushion protecting tooling from impact damage.
Chemical Process Valves
Operates linear valves or dampers in aggressive chemical atmospheres where standard polyurethane seals would degrade, leveraging FKM's superior chemical resistance.
Is the Airtac SC50 Standard Cylinder SC50X110H the Right Cylinder?
Choose the SC50 bore when your application needs roughly 1000 N of force at standard plant pressure; for lighter loads around 630 N the SC40 bore may save space, while for heavier work near 1560 N the SC63 is the next step up. This 110 mm stroke is within the standard range for the 50 mm bore (max standard 1200 mm).
When replacing an existing cylinder, match five points: 50 mm bore, 110 mm stroke, PT port thread, the required mounting accessory (this is a basic body style, so order brackets separately if needed), and the magnet option (this model has no built-in magnet). For strokes over 300 mm on this bore, consider an external guide to protect the 20 mm rod from side-load bending.
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 SC50X110H FAQ
At 0.7 MPa supply pressure the SC50 bore generates 1374 N of push force on the outstroke. The pull force on the retract stroke at the same pressure is 825 N, accounting for the 20 mm rod area.
No. The 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 profiles differ. It is a direct dimensional match only for another AirTAC SC50 tie-rod cylinder with the same stroke, port type, and mounting configuration.
