About the Airtac SC80 Standard Cylinder SC80X250H
The SC80X250H is an 80 mm bore, 250 mm stroke double-acting pneumatic cylinder engineered for high-temperature environments. Fitted with Viton (FKM) seals, it operates reliably from 0 to +150 °C, making it suitable for autoclaves, foundries, and hot pressing applications where standard seals would degrade. The unit delivers a push force of 2513 N at 0.5 MPa and up to 4523 N at the maximum operating pressure of 0.9 MPa.
This tie-rod cylinder uses a 25 mm diameter piston rod with an M20x1.5 male thread and PT3/8 air ports. The 28 mm air cushion is adjustable, allowing you to dial in smooth deceleration for payloads up to the cylinder's 513 kgf theoretical limit. The body length A is 182 mm, giving a total extended length of approximately 432 mm for this 250 mm stroke model.

Where the Airtac SC80 Standard Cylinder SC80X250H Is Used
High-Temperature Actuation
Viton seals enable continuous operation in ambient temperatures up to 150°C, ideal for autoclave doors, drying ovens, and hot stamping presses.
Material Handling in Foundries
The 2513 N push force at 0.5 MPa handles heavy molds and castings. The adjustable cushion protects the cylinder and tooling from impact damage during high-speed cycles.
Clamping & Pressing
Delivers up to 4523 N of clamping force at 0.9 MPa. The rigid tie-rod construction and 25 mm rod resist deflection, maintaining alignment in press-fit and bonding fixtures.
Is the Airtac SC80 Standard Cylinder SC80X250H the Right Cylinder?
For applications requiring more force, consider stepping up to the 100 mm bore SC100 series, which provides 3927 N of push force at 0.5 MPa. If space is constrained and less force is acceptable, the 63 mm bore SC63 series offers 1559 N at the same pressure. This 250 mm stroke is within the standard range for the 80 mm bore, which supports standard strokes up to 1500 mm.
To ensure a correct replacement, match five key points: bore (80 mm), stroke (250 mm), port thread (PT3/8), mounting accessory (basic, no bracket), and seal material (Viton). This model does not include a built-in magnet; if you need sensor mounting, specify the -S suffix. For strokes of 300 mm or longer, evaluate side loads carefully—an unsupported rod can bend under lateral force, so consider an external guide or a guided 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 SC80 Standard Cylinder SC80X250H FAQ
At the standard operating pressure of 0.5 MPa, the push force is 2513 N and the pull force is 2268 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 4523 N. The theoretical maximum force at 1.0 MPa is 513 kgf.
No. The AirTAC SC series is a tie-rod cylinder with a shorter body length than an ISO 15552 profile cylinder, so it is not dimensionally interchangeable. It is a direct replacement only for another AirTAC SC80 tie-rod cylinder with matching stroke, port thread, and mounting configuration.
