About the Airtac SC80 Standard Cylinder SC80X538S
The SC80X538S is an 80 mm bore double-acting tie-rod cylinder with a 538 mm stroke, factory-equipped with a built-in magnet (-S suffix) so CMSG/DMSG/EMSG reed or solid-state sensors clamp directly onto the barrel for non-contact position sensing. At 0.5 MPa air pressure it generates 2513 N pushing and 2268 N pulling, rising to a substantial 4523 N push at the 0.9 MPa maximum operating pressure.
This model uses a 25 mm diameter piston rod with M20x1.5 male threads and PT3/8 ports. The adjustable pneumatic cushion at each end (28 mm cushion length) decelerates the piston smoothly, and the total extended body length is approximately 720 mm (182 mm body length A + 538 mm stroke). The standard TPU seals give an operating temperature range of -20 to +70 °C.

Where the Airtac SC80 Standard Cylinder SC80X538S Is Used
Long-Reach Part Transfer
The 538 mm stroke combined with 2513 N of push force at 0.5 MPa moves heavy components across wide conveyor gaps or between distant pallet stations, with the magnetic piston signalling end-of-stroke to the PLC.
Automated Clamping & Fixturing
Delivers consistent 2268 N pull force for draw-bar clamping on CNC fixtures. The built-in magnet allows dual sensor mounting to confirm both clamped and unclamped positions.
Diverter Gate Actuation
Operates large diverter gates on gravity or powered roller conveyors. The 28 mm adjustable cushion absorbs the kinetic energy of the gate at end of travel, reducing noise and mechanical shock.
Is the Airtac SC80 Standard Cylinder SC80X538S the Right Cylinder?
Choose the SC80 when your application needs roughly 2500 N of push force at standard plant air; if you require closer to 4000 N at 0.5 MPa, step up to the SC100 bore (3927 N push). For strokes at or beyond 300 mm like this 538 mm unit, be aware that an unsupported 25 mm rod is vulnerable to bending under side load — fit an external linear guide or switch to a guided cylinder if the load is not perfectly axial. To replace an existing SC80X538S, match five points: 80 mm bore, 538 mm stroke, PT3/8 port thread, the built-in magnet (-S), and the basic (no bracket) mounting configuration.
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 SC80X538S FAQ
At 0.7 MPa (7 bar) the SC80 bore generates 3518 N of push force and 3175 N of pull force. The maximum operating pressure is 1.0 MPa, producing 4523 N push. These figures are theoretical; factor in a 30-50% safety margin for dynamic applications.
Yes. The -S suffix in SC80X538S means a magnet is built into the piston. You can clamp AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the barrel's tie-rod slots to detect piston position without any additional brackets.
