About the Airtac SC80 Standard Cylinder SC80X835
The AirTAC SC80X835 is a double-acting tie-rod cylinder delivering 2513 N of push force at 0.5 MPa, scaling up to 4523 N at the maximum operating pressure of 0.9 MPa. With an 80 mm bore and an 835 mm stroke, this model uses a 25 mm diameter piston rod and PT3/8 ports, making it a robust choice for medium-to-long linear stroke applications.
This cylinder features a body length A of 182 mm and an adjustable pneumatic cushion of 28 mm at each end to decelerate the piston smoothly. The standard operating temperature range is -20 to +70 °C with the default TPU seals, and the unit is designed for filtered air at 40 µm, operating reliably between 0.15 and 1.0 MPa.

Where the Airtac SC80 Standard Cylinder SC80X835 Is Used
Material Handling Gates
Operates diverter gates or stops on conveyor lines, using the 835 mm stroke to redirect packages or pallets between lanes with a push force of 2513 N at standard plant pressure.
Press-Feed Mechanisms
Advances strip or sheet stock into stamping presses. The long 835 mm stroke clears the die area completely, while the adjustable cushion protects tooling from impact damage at cycle end.
Pallet Layer Positioning
Positions a pallet stack vertically in an automated warehouse cell. The 25 mm rod and tie-rod construction handle repetitive lifting cycles, with the 28 mm cushion absorbing energy smoothly.
Is the Airtac SC80 Standard Cylinder SC80X835 the Right Cylinder?
For applications requiring slightly less force, stepping down to a 63 mm bore reduces push force to 1559 N at 0.5 MPa, while moving up to a 100 mm bore increases it to 3927 N. The SC80X835 has a stroke of 835 mm, which is well within the 1500 mm maximum standard stroke for this bore size. For strokes of this length, ensure the load is guided externally to prevent side-load bending on the 25 mm rod, or consider a guided cylinder if side forces are present.
When replacing an existing cylinder, match five key points: the 80 mm bore, 835 mm stroke, PT3/8 port thread, the basic (no bracket) mounting configuration, and the absence of a built-in magnet. This model is a direct replacement for another AirTAC SC80X835 or an equivalent tie-rod cylinder with these exact 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 SC80X835 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, the push force increases to 4523 N. The theoretical maximum force at 1.0 MPa is 513 kgf.
No, the SC80X835 is a double-acting cylinder and will not hold its position if air pressure is lost or the directional valve is centered. The adjustable air cushion only decelerates the piston at the stroke ends; it is not a locking or holding brake. For position holding, you must add an external rod lock or a pilot-operated check valve.
