About the Airtac SC80 Standard Cylinder SC80X135
The SC80X135 is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, 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. With an 80 mm bore and a 135 mm stroke, this model uses a 25 mm diameter piston rod with an M20x1.5 male thread, providing robust linear actuation for medium-to-heavy industrial tasks.
This cylinder's body length is 182 mm, resulting in a total extended length of approximately 317 mm. It features an adjustable pneumatic cushion (28 mm length) at both ends to decelerate the piston smoothly, reducing end-of-stroke impact. The standard PT3/8 port and TPU seals with a -20 to +70 °C operating range make it a versatile workhorse for general factory automation.

Where the Airtac SC80 Standard Cylinder SC80X135 Is Used
Package Sorting Gates
The 2513 N push force at 0.5 MPa easily diverts medium-weight packages on conveyor lines, with the 135 mm stroke providing a clean, decisive push action.
Clamping & Fixturing
Ideal for workholding in machining centers, the 25 mm rod and adjustable cushion ensure stable, vibration-dampened clamping without marking delicate parts.
Press-Fit Assembly
Delivers a controlled 4523 N of force at 0.9 MPa for pressing bearings or bushings, with the tie-rod construction providing rigidity under high thrust.
Is the Airtac SC80 Standard Cylinder SC80X135 the Right Cylinder?
Select the SC80X135 when your application requires a force step up from the 63 mm bore, which provides 1559 N at 0.5 MPa. If you need more power, the 100 mm bore delivers 3927 N at the same pressure. For this 135 mm stroke, side loading is typically not a primary concern, but always ensure the load is guided externally if any lateral force is present to protect the rod bearing.
To ensure a correct replacement, match five key points: the 80 mm bore, the 135 mm stroke, the PT3/8 port thread, the basic (no bracket) mounting configuration, and the absence of a built-in magnet. This model is a standard 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 SC80 Standard Cylinder SC80X135 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 SC80X135 is a double-acting cylinder and will not hold its position if air pressure is exhausted or lost. The adjustable air cushions only decelerate the piston at the end of its stroke. For load holding, you must add an external rod brake, a mechanical lock, or a pilot-operated check valve.
