About the Airtac SC80 Standard Cylinder SC80X403S
The AirTAC SC80X403S is a double-acting tie-rod cylinder with an 80 mm bore and a 403 mm stroke, factory-equipped with a built-in magnet. The magnet allows CMSG/DMSG/EMSG reed or solid-state sensors to clamp directly onto the barrel for rod-position feedback without extra brackets. At 0.5 MPa air pressure it generates 2513 N pushing force and 2268 N pulling force, rising to 4523 N push at the 0.9 MPa maximum operating pressure.
This model uses a 25 mm diameter piston rod with an M20x1.5 male thread and PT3/8 ports. The adjustable air cushion at each end (28 mm cushion length) decelerates the piston smoothly, protecting end caps during high-cycle duty. The body length A is 182 mm, giving a total extended length of approximately 585 mm. Standard TPU seals suit ambient temperatures from -20 to +70 °C.

Where the Airtac SC80 Standard Cylinder SC80X403S Is Used
Material Handling Gates
The 403 mm stroke and 2513 N push force at 0.5 MPa operate diverter gates and transfer stations on packaging conveyors. The built-in magnet provides end-of-stroke confirmation via barrel-mounted sensors.
Press-Feed Mechanisms
Delivers a controlled 4523 N at 0.9 MPa to advance strip stock into stamping presses. The adjustable cushion absorbs the inertia of the feed carriage at both ends of the 403 mm travel.
Palletising Pushers
Pushes filled cases onto pallets with consistent force. The 25 mm rod and tie-rod construction handle repetitive impact loading, while the magnet enables sensor-based cycle counting.
Is the Airtac SC80 Standard Cylinder SC80X403S the Right Cylinder?
Choose the SC80X403S when your application needs roughly 2500 N of push force at standard shop air. If you need more force, stepping up to the SC100 bore delivers 3927 N at 0.5 MPa; if you need less, the SC63 bore provides 1559 N at the same pressure. The 403 mm stroke is within the 1500 mm maximum standard stroke for bore 80, so this is a standard-stroke model.
For strokes of 300 mm or longer, be cautious with side loads. An unsupported 25 mm rod extending 403 mm can bend under even moderate lateral force. Use an external linear guide or a guided cylinder if the load is not perfectly axial. When replacing an existing cylinder, match five points: 80 mm bore, 403 mm stroke, PT3/8 port thread, the built-in magnet (-S suffix), and the basic (no bracket) mounting style.
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 SC80X403S FAQ
At 0.5 MPa the cylinder pushes with 2513 N and pulls with 2268 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 4523 N. The theoretical maximum at 1.0 MPa is 513 kgf (5030 N).
Yes. The -S suffix in SC80X403S means a magnet is built into the piston. You can clamp AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the barrel tie-rod slots to detect rod position without any additional mounting hardware.
