About the Airtac SC80 Standard Cylinder SC80X65S
The SC80X65S is an 80 mm bore double-acting pneumatic cylinder delivering 2513 N of push force at 0.5 MPa (4523 N at the 0.9 MPa maximum operating pressure). Its 65 mm stroke is well within the 1500 mm maximum standard stroke for this bore, making it a stock-friendly choice for compact linear actuation.
This model includes the built-in -S magnet, allowing CMSG, DMSG, or EMSG reed and solid-state sensors to clamp directly onto the tie-rod barrel for non-contact position sensing. The cylinder uses a 25 mm diameter piston rod with an M20x1.5 male thread, PT3/8 ports, and an adjustable air cushion length of 28 mm to decelerate the load smoothly at end-of-stroke.

Where the Airtac SC80 Standard Cylinder SC80X65S Is Used
Sortation Gate Actuation
The 65 mm stroke and sensor-ready magnet make this cylinder ideal for high-speed diverter gates on package sorters, where position confirmation is needed at both ends of travel.
Automated Clamping Fixture
Delivers over 2500 N of clamping force at standard line pressure. The built-in magnet enables sensor feedback to confirm the clamp is fully engaged before a machining cycle starts.
Press-Fit Assembly Station
The 80 mm bore provides the thrust needed for light press-fit operations. The -S magnet allows the control system to monitor ram position and cycle count accurately.
Is the Airtac SC80 Standard Cylinder SC80X65S the Right Cylinder?
For applications needing less force, stepping down to the 63 mm bore SC63 series provides 1559 N at 0.5 MPa, while moving up to the 100 mm bore SC100 series nearly doubles the push to 3927 N. The -S magnet variant is essential if you require electronic end-of-stroke confirmation; without it, only external limit switches can be used.
When replacing an existing cylinder, match five points: 80 mm bore, 65 mm stroke, PT3/8 port thread, the built-in magnet (-S suffix), and the basic mounting style. The SC series 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 SC80X65S FAQ
At 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, push force reaches 4523 N. The theoretical maximum at 1.0 MPa is 513 kgf.
Yes. The -S suffix designates a built-in magnet on the piston, which is required for AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors to detect position when clamped to the cylinder barrel.
