About the Airtac SC80 Standard Cylinder SC80X185S
The SC80X185S is a double-acting tie-rod cylinder with an 80 mm bore and 185 mm stroke, equipped with a built-in magnet that lets you clamp CMSG, DMSG, or EMSG reed and solid-state sensors directly onto the barrel for reliable end-of-stroke detection. At 0.5 MPa it pushes with 2513 N and pulls with 2268 N, while at the maximum operating pressure of 0.9 MPa the thrust reaches 4523 N—enough for medium-heavy clamping, pressing, and transfer tasks.
Its 25 mm diameter piston rod and 28 mm adjustable air cushion at each end deliver smooth deceleration without any external shock absorbers. The body length A is 182 mm, giving a compact extended length of approximately 367 mm for this 185 mm stroke. PT1/4 ports and an M20x1.5 rod thread keep the connection points standard and easy to plumb.

Where the Airtac SC80 Standard Cylinder SC80X185S Is Used
Part Transfer & Indexing
The 2513 N push force at 0.5 MPa moves pallets or fixtures between conveyor stations. The built-in magnet lets you confirm extend and retract positions with CMSG sensors wired to the PLC.
Clamping & Holding Fixtures
Apply up to 4523 N at 0.9 MPa to hold workpieces during machining or welding. The adjustable cushion protects the fixture from impact shock on every cycle.
Bin Diverter & Gate Actuation
Stroke a diverter gate 185 mm in a sorting line. The 28 mm cushion absorbs the gate’s inertia at end-of-travel, keeping noise and vibration low in a busy distribution centre.
Is the Airtac SC80 Standard Cylinder SC80X185S the Right Cylinder?
Choose the SC80 bore when a 63 mm cylinder (1559 N push at 0.5 MPa) is borderline and you need the next force step without jumping to 100 mm. If your load is lighter, stepping down to SC63 saves air and space; for heavier loads the SC100 delivers 3927 N at the same pressure. For this 185 mm stroke, side-load bending is normally not a concern on the 25 mm rod, but if the load is not guided or the mounting introduces a moment, add an external linear guide or switch to a guided cylinder. To replace an existing unit, match all five points: 80 mm bore, 185 mm stroke, PT thread, the -S magnet option for sensor mounting, 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 SC80X185S FAQ
At 0.5 MPa the cylinder pushes with 2513 N and pulls with 2268 N. At 0.7 MPa the push force is 3518 N, and at the maximum operating pressure of 0.9 MPa it reaches 4523 N. The theoretical maximum at 1.0 MPa is 513 kgf.
Yes. The -S suffix in SC80X185S means a magnet is built into the piston, so AirTAC CMSG (reed), DMSG, or EMSG (solid-state) sensors clip directly onto the barrel’s sensor groove. You get non-contact position feedback without any extra brackets or modifications.
