About the Airtac SC80 Standard Cylinder SC80X950
The AirTAC SC80X950 is a double-acting tie-rod cylinder delivering a push force of 2513 N at 0.5 MPa and up to 4523 N at 0.9 MPa operating pressure. With an 80 mm bore and a 950 mm stroke, its 25 mm piston rod provides robust linear thrust for medium-to-long travel applications.
This model features a body length A of 182 mm and an adjustable air cushion of 28 mm at each end to decelerate the piston smoothly. The standard PT3/8 port and M20x1.5 rod thread ensure straightforward pneumatic connections, while the TPU seals offer reliable operation from -20 to +70 C.

Where the Airtac SC80 Standard Cylinder SC80X950 Is Used
Long-Reach Part Transfer
The 950 mm stroke pushes or pulls components between distant conveyor stations, with the 2513 N force at 0.5 MPa easily handling palletised goods.
Clamping & Fixturing
Applies consistent clamping pressure across a wide work area. The adjustable cushion protects the fixture and workpiece from impact at the end of the 950 mm travel.
Bin Diverter Actuation
Directs product flow in gravity chutes or sorting systems. The 25 mm rod and tie-rod construction provide the stiffness needed for repeated, full-stroke cycling.
Is the Airtac SC80 Standard Cylinder SC80X950 the Right Cylinder?
For applications needing more force, stepping up to the 100 mm bore provides 3927 N at 0.5 MPa; for a lighter, more compact solution, the 63 mm bore delivers 1559 N. At a 950 mm stroke, the unsupported rod length is significant—any side load or misalignment can cause rod bending and premature bearing wear. Use an external guide rail or a guided cylinder if the load is not perfectly axial.
To replace an existing unit, match five points exactly: 80 mm bore, 950 mm stroke, PT3/8 port thread, basic (no bracket) mounting, and no magnet. This SC80X950 is a genuine AirTAC tie-rod cylinder and is dimensionally interchangeable only with another AirTAC SC80 of the same stroke and port configuration.
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 SC80X950 FAQ
At 0.7 MPa operating pressure, the theoretical push force is 3518 N and the pull force is 2268 N. These values assume a static piston; for dynamic loads, factor in a safety margin for friction and inertia.
Only if the load is perfectly axial with no side forces. A 950 mm stroke on an 80 mm bore creates a long lever arm—any side load will bend the 25 mm rod and damage the bearing. For non-axial loads, install an external linear guide or use a guided cylinder variant.
