About the Airtac SC80 Standard Cylinder SC80X1990S
The AirTAC SC80X1990S is a double-acting tie-rod cylinder delivering 2513 N of push force at 0.5 MPa (4523 N at 0.9 MPa). With a 1990 mm stroke, this non-standard model extends far beyond the standard 1500 mm maximum, making it a made-to-order solution for long linear movements. The 25 mm diameter rod and 28 mm adjustable air cushion at each end help manage end-of-stroke impact.
This unit 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 precise, non-contact position sensing. The body length A is 182 mm, giving a total extended length of approximately 2172 mm. Ports are PT3/8 with an M20x1.5 rod thread.

Where the Airtac SC80 Standard Cylinder SC80X1990S Is Used
Long-Stroke Material Pusher
The 1990 mm stroke is ideal for pushing heavy pallets or large components across wide conveyor transfers in logistics and distribution centers.
Automated Panel Indexing
Used in woodworking or metal fabrication to index large panels through a multi-station process, with sensor feedback from the built-in magnet ensuring precise positioning.
Agricultural Equipment Actuation
Provides the long, linear motion needed for opening and closing large hopper doors or adjusting wide implements on farming machinery.
Is the Airtac SC80 Standard Cylinder SC80X1990S the Right Cylinder?
For a 1990 mm stroke, the 80 mm bore provides a robust 25 mm rod that resists bending better than smaller bores, but at this extreme length, side loading must be strictly avoided. Always guide the load externally or pair the cylinder with a linear rail system to prevent rod bearing damage. If more force is needed, stepping up to the 100 mm bore offers 3927 N at 0.5 MPa; for a lighter, more compact setup, the 63 mm bore provides 1559 N.
To ensure a direct replacement, match five key points: bore (80 mm), stroke (1990 mm), PT3/8 port thread, the built-in magnet (-S), and the basic mounting style. This is a tie-rod cylinder, not an ISO 15552 profile, so dimensional interchangeability is limited to other AirTAC SC80 tie-rod units with the same specifications.
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 SC80X1990S FAQ
At 0.5 MPa, it generates 2513 N pushing and 2268 N pulling. The maximum pushing force at 0.9 MPa operating pressure is 4523 N.
For strokes this long, the rod must never bear side loads. Use an external linear guide or a guided cylinder configuration to carry the load, allowing the SC cylinder to provide only the axial push-pull force. This prevents premature seal wear and rod bending.
