About the Airtac SC50 Standard Cylinder SC50X100H
The AirTAC SC50X100H is a double-acting tie-rod cylinder equipped with high-temperature Viton (FKM) seals, extending its operating range to 0–150 °C for demanding thermal environments. With a 50 mm bore and 100 mm stroke, it generates a theoretical push force of 982 N at 0.5 MPa and up to 1767 N at 0.9 MPa, making it a capable mid-range actuator for hot-process automation.
This model features a 20 mm diameter piston rod with M16x1.5 male threads and PT1/4 ports. The adjustable air cushion at each end is 21 mm long, providing smooth deceleration. The body length A is 150 mm, giving a total extended length of approximately 250 mm for this stroke.

Where the Airtac SC50 Standard Cylinder SC50X100H Is Used
High-Temperature Automation
Viton seals enable reliable actuation in ovens, autoclaves, and foundry equipment where ambient temperatures reach up to 150 °C, far beyond the limit of standard seals.
Hot Press & Molding
Delivers 1767 N of clamping force at 0.9 MPa for heated platen presses, thermoforming tools, and rubber molding machines requiring consistent force under heat.
Material Handling Near Dryers
Operates gates, diverters, and pushers on conveyor lines passing through drying or curing ovens, where standard cylinders would experience premature seal failure.
Is the Airtac SC50 Standard Cylinder SC50X100H the Right Cylinder?
Choose the SC50X100H when your application requires a force of roughly 982 N at standard 0.5 MPa shop air, and the ambient temperature exceeds 70 °C. If you need more force, stepping up to the 63 mm bore provides 1559 N at the same pressure; for a lighter, more compact solution, the 40 mm bore delivers 628 N. The Viton seal (H suffix) is critical for high-temperature or chemically aggressive environments where standard TPU seals would degrade.
For a drop-in replacement, match five key points: 50 mm bore, 100 mm stroke, PT port thread, basic mounting (no integrated bracket), and the high-temperature seal material. This 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 SC50X100H FAQ
The theoretical push force at 0.7 MPa (7 bar) is 1374 N. The pull force on the retract stroke is lower due to the rod area, producing 825 N at 0.5 MPa. For precise dynamic sizing, factor in your application's friction and load angle.
No. The AirTAC SC series is a tie-rod cylinder with a shorter overall body length than an ISO 15552 profile cylinder. It will only drop-in replace another AirTAC SC tie-rod cylinder with identical bore, stroke, and port thread. Always verify the body length A (150 mm) against your existing unit.
