About the Airtac SC80 Standard Cylinder SC80X950STC
The SC80X950STC is a double-acting pneumatic cylinder delivering 2513 N push force at 0.5 MPa and up to 4523 N at 0.9 MPa. Its 80 mm bore and 950 mm stroke suit long linear movements where consistent thrust is required.
This model includes a built-in magnet (-S) for CMSG/DMSG/EMSG sensors and a centre trunnion mount (TC) with TCM1 bracket (F-SC80TC) for pivoting loads. The 25 mm rod and 28 mm adjustable air cushion help manage end-of-stroke deceleration on this extended reach.

Where the Airtac SC80 Standard Cylinder SC80X950STC Is Used
Long-Stroke Part Transfer
Moves components 950 mm between conveyor lines or assembly stations, with sensor confirmation via the built-in magnet.
Pivoting Clamp or Gate
The TC centre trunnion mount allows the cylinder to swing, ideal for actuating a pivoting gate or clamp on heavy-duty fixtures.
Pallet or Box Pusher
Provides the extended reach and 2513 N push force needed to transfer loaded pallets or large boxes onto roller beds.
Is the Airtac SC80 Standard Cylinder SC80X950STC the Right Cylinder?
For higher force, step up to the 100 mm bore (3927 N at 0.5 MPa); for a more compact build, the 63 mm bore offers 1559 N. At 950 mm stroke, the unsupported rod length is significant—side loads can cause rod bending or bearing wear. Use an external linear guide or a guided cylinder if the load is not purely axial.
When replacing, match bore (80 mm), stroke (950 mm), PT port thread, centre trunnion mount (TC with TCM1), and the built-in magnet (-S). This SC tie-rod cylinder is shorter than an ISO 15552 profile and is not dimensionally interchangeable with that standard.
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 SC80X950STC FAQ
At 0.5 MPa it produces 2513 N push and 2268 N pull. At 0.7 MPa push force is 3518 N, and at the maximum operating pressure of 0.9 MPa it reaches 4523 N.
No. The 25 mm rod is not designed for unsupported side loads at this stroke length. You must use an external guide rail or switch to a guided cylinder to prevent rod bending and premature seal failure.
