About the Airtac SC80 Standard Cylinder SC80X865S
The AirTAC SC80X865S is a double-acting single-rod pneumatic cylinder delivering 2513 N of push force at 0.5 MPa (4523 N at 0.9 MPa). Its 25 mm diameter rod and 865 mm stroke suit medium-force linear tasks requiring extended reach, with an adjustable air cushion softening the piston deceleration over the final 28 mm of travel.
This model includes a built-in magnet (-S suffix), allowing CMSG, DMSG, or EMSG reed and solid-state sensors to clamp directly onto the tie-rod barrel for contactless position sensing. The body length A is 182 mm, giving a total extended length of approximately 1047 mm. Operating pressure is 0.15–1.0 MPa with standard TPU seals rated for -20 to +70 °C.

Where the Airtac SC80 Standard Cylinder SC80X865S Is Used
Long-Reach Part Transfer
The 865 mm stroke moves components between distant conveyor lanes or workstations. The built-in magnet enables end-of-stroke confirmation with CMSG/DMSG sensors for automated line pacing.
Automated Gluing or Dispensing
Delivers consistent 2513 N push at 0.5 MPa to depress a dispensing head across a wide panel. Sensor feedback from the -S magnet confirms full retraction before the next cycle.
Pallet Layer Alignment
Pushes a row of cases into alignment on a palletising station. The adjustable cushion absorbs impact energy smoothly, while the tie-rod design handles repetitive industrial cycling.
Is the Airtac SC80 Standard Cylinder SC80X865S the Right Cylinder?
For applications needing more force, stepping up to the 100 mm bore SC100 series provides 3927 N push at 0.5 MPa. If a shorter, more compact build is acceptable, the 63 mm bore delivers 1559 N at the same pressure. At 865 mm of stroke, the unsupported rod length is substantial; any side load or off-axis mounting can cause rod bending and premature bearing wear, so an external linear guide or a guided cylinder is strongly recommended.
When replacing an existing cylinder, match five points: 80 mm bore, 865 mm stroke, PT (1/4 inch) port thread, the built-in magnet for sensor compatibility, and the basic (no bracket) mounting configuration. This SC 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 SC80X865S 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. These values assume clean, filtered air at 40 µm and standard operating conditions.
Yes. The -S suffix indicates a built-in magnet inside the piston, making it compatible with AirTAC CMSG (reed) and DMSG/EMSG (solid-state) sensors. The sensors clamp onto the tie-rod barrel without needing additional brackets.
