About the Airtac SC80 Standard Cylinder SC80X85S
The AirTAC SC80X85S is an 80 mm bore double-acting tie-rod cylinder delivering 2513 N push force at 0.5 MPa and up to 4523 N at 0.9 MPa. Its 85 mm stroke suits medium-travel clamping and positioning tasks, while the built-in magnet allows direct mounting of CMSG/DMSG/EMSG sensors for reliable end-of-stroke detection.
This model uses a 25 mm diameter piston rod with M20x1.5 male threads and PT3/8 ports. The body length A is 182 mm, giving a total extended length of approximately 267 mm. An adjustable air cushion (28 mm length) decelerates the piston quietly, and the standard TPU seals operate from -20 to +70 °C.

Where the Airtac SC80 Standard Cylinder SC80X85S Is Used
Conveyor Stop / Gate
The 80 mm bore provides ample force to raise and lower product stops or divert gates on packaging and assembly conveyors, with sensor feedback confirming position.
Clamping & Fixturing
Delivers consistent 2513 N clamping force at standard shop air. The built-in magnet enables compact sensor mounting for part-present confirmation in automated CNC or welding fixtures.
Palletising Pusher
Used as a short-stroke pusher to align cases or pallets. The tie-rod construction handles repetitive impact better than profile cylinders in demanding logistics environments.
Is the Airtac SC80 Standard Cylinder SC80X85S the Right Cylinder?
For applications needing more force, step up to the 100 mm bore SC100 series which provides 3927 N at 0.5 MPa. If 80 mm is sufficient but a shorter stroke is required, the SC80X75 or SC80X50 are standard alternatives. Always match the port thread (PT), mounting style, and magnet option when replacing an existing cylinder.
At 85 mm stroke, the 25 mm rod is well supported for axial loads. If side loads are present, add an external linear guide to protect the rod bearing from bending and uneven seal wear.
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 SC80X85S FAQ
At 0.7 MPa (7 bar) the SC80X85S generates 3518 N of push force. The pull force at the same pressure is 2268 N, accounting for the 25 mm rod area.
Yes. The -S suffix indicates a built-in magnet inside the piston. You can directly mount AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors on the barrel tie-rods to detect piston position.
