About the Airtac SC80 Standard Cylinder SC80X800STC
The SC80X800STC delivers 2513 N of push force at 0.5 MPa, scaling up to 4523 N at the maximum operating pressure of 0.9 MPa. This 80 mm bore double-acting cylinder features an 800 mm stroke, a 25 mm diameter piston rod, and a 28 mm adjustable air cushion at each end to decelerate the load smoothly.
This model is configured with a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors and a centre trunnion (TC) mount, supplied with the TCM1 bracket (F-SC80TC), allowing the cylinder to pivot. The body length A is 182 mm, making the total extended length approximately 982 mm. It uses standard PT ports (PT3/8) and TPU seals for operation in -20 to +70 C.

Where the Airtac SC80 Standard Cylinder SC80X800STC Is Used
Long-Stroke Material Transfer
The 800 mm stroke and 2513 N push force at 0.5 MPa efficiently transfer heavy workpieces between distant conveyor stations. The centre trunnion mount allows the cylinder to swing, accommodating the motion arc.
Automated Welding Fixtures
With a built-in magnet for end-of-stroke sensing, this cylinder confirms clamp position in automated welding cells. The adjustable cushion protects the fixture from impact at high cycle rates.
Pallet Dispenser Pivoting Gate
The TC trunnion mount enables a pivoting action to control the release of pallets in a dispenser. The 4523 N force at 0.9 MPa provides ample power to hold and release heavy stacks.
Is the Airtac SC80 Standard Cylinder SC80X800STC the Right Cylinder?
For higher force requirements, stepping up to a 100 mm bore provides 3927 N of push at 0.5 MPa. If space is constrained and less force is needed, a 63 mm bore offers 1559 N. This 800 mm stroke requires careful management of side loads; an external guide or a guided cylinder is strongly recommended to prevent bending stress on the 25 mm rod and rod bearing, ensuring long service life.
To replace an existing unit, match five key points: the 80 mm bore, 800 mm stroke, PT3/8 port thread, the centre trunnion (TC) mounting accessory, and the built-in magnet (-S) for sensor compatibility. This tie-rod cylinder is shorter than an ISO 15552 profile and is not dimensionally interchangeable with that standard.
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 SC80X800STC FAQ
At the standard 0.5 MPa operating pressure, the cylinder provides 2513 N of push force and 2268 N of pull force. At the maximum operating pressure of 0.9 MPa, the push force increases to 4523 N.
No. The AirTAC SC series is a tie-rod cylinder that is shorter in overall length than a comparable ISO 15552 profile cylinder. It is not dimensionally interchangeable. It must be replaced with another AirTAC SC80 tie-rod cylinder matching the 800 mm stroke, TC mount, and magnet option.
