About the Airtac SC80 Standard Cylinder SC80X65
The SC80X65 is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, combining an 80 mm bore with a 65 mm stroke. At 0.5 MPa it generates 2513 N of push force, making it a capable actuator for medium-duty clamping and pressing tasks where a compact extended length is beneficial.
This model features a 25 mm piston rod with M20x1.5 threads and PT3/8 ports. The body length A is 182 mm, giving a total extended length of approximately 247 mm. An adjustable air cushion softens end-of-stroke impact over the 28 mm cushion length, and the standard TPU seals suit operating temperatures from -20 to +70 °C.

Where the Airtac SC80 Standard Cylinder SC80X65 Is Used
Part Stops & Gates
The 2513 N push force at 0.5 MPa easily halts totes or pallets on a conveyor line, and the 65 mm stroke provides a crisp, fast-acting stop motion.
Light Press-Fit Assembly
Ideal for pressing bushings or bearings into housings where a short, controlled 65 mm stroke and 2.5 kN force ensure consistent insertion without over-travel.
Clamping Fixtures
Delivers secure workpiece clamping in machining or welding jigs. The adjustable cushion prevents vibration at the end of the 65 mm stroke, protecting the fixture.
Is the Airtac SC80 Standard Cylinder SC80X65 the Right Cylinder?
Choose the SC80 bore when the SC63's 1559 N at 0.5 MPa is borderline but a full SC100 (3927 N) is oversized. This 65 mm stroke is a standard length within the 80 mm bore's 1500 mm maximum.
For replacement, match five points: 80 mm bore, 65 mm stroke, PT3/8 port thread, basic mounting (no bracket), and confirm the magnet option (this model has no built-in magnet). The SC 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 SC80 Standard Cylinder SC80X65 FAQ
At the standard 0.5 MPa operating pressure, push force is 2513 N and pull force is 2268 N. At the maximum operating pressure of 0.9 MPa, push force reaches 4523 N. The theoretical maximum at 1.0 MPa is 513 kgf.
This specific model code SC80X65 does not include the -S magnet option, so the piston does not have a built-in magnetic ring. To use CMSG or DMSG sensors, order the SC80X65-S variant which includes the magnet. The standard SC80X65 requires external limit switches if position sensing is needed.
