About the Airtac SC80 Standard Cylinder SC80X505
The AirTAC SC80X505 is an 80 mm bore double-acting tie-rod cylinder delivering a push force of 2513 N at 0.5 MPa and up to 4523 N at the maximum operating pressure of 0.9 MPa. Its 25 mm diameter piston rod and 28 mm adjustable air cushion make it a robust choice for medium-to-heavy linear actuation tasks requiring a half-meter stroke.
With a body length A of 182 mm, the total extended length is approximately 687 mm. This model uses PT3/8 pneumatic ports and an M20x1.5 rod thread, providing a solid connection for tooling. The standard TPU seals offer reliable operation in ambient temperatures from -20 to +70 °C.

Where the Airtac SC80 Standard Cylinder SC80X505 Is Used
Material Transfer
Pushes or diverts boxes and components on a conveyor line, using the 505 mm stroke to move items fully across a wide belt or between two parallel conveyors.
Press-Fit Assembly
Provides the controlled 2513 N force at 0.5 MPa for pressing bearings, bushings, or pins into housings in a semi-automated assembly station.
Sawmill & Wood Processing
Actuates a log stop or board flipper gate, where the 80 mm bore delivers the necessary push force and the tie-rod design withstands dusty industrial environments.
Is the Airtac SC80 Standard Cylinder SC80X505 the Right Cylinder?
For applications needing more force, stepping up to the 100 mm bore SC100 series provides 3927 N of push force at the same 0.5 MPa pressure. If a shorter, more compact cylinder is acceptable, the 63 mm bore SC63 delivers 1559 N. To ensure a successful replacement, match five key points: 80 mm bore, 505 mm stroke, PT3/8 port thread, basic (no bracket) mounting, and the absence of a built-in magnet.
At a 505 mm stroke, the extended 25 mm rod is susceptible to bending under side loads. Avoid direct lateral forces on the rod end; use an external linear guide or a guided cylinder assembly to absorb the side load and protect the rod bearing and piston seals from premature wear.
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 SC80X505 FAQ
At 0.7 MPa operating pressure, the theoretical push force is 3518 N and the pull force on the retract stroke is 2268 N. These values assume a static, non-shock load condition.
This specific model code SC80X505 does not include the '-S' magnet option, so the piston does not have a magnetic ring. To use CMSG or DMSG sensors for position feedback, you would need to order the SC80X505-S variant, which has a built-in magnet.
