About the Airtac SC80 Standard Cylinder SC80X770
The AirTAC SC80X770 is a double-acting pneumatic cylinder delivering a push force of 2513 N at 0.5 MPa, scaling up to 4523 N at the maximum operating pressure of 0.9 MPa. With an 80 mm bore and a 770 mm stroke, this model features a 25 mm diameter piston rod and PT3/8 ports, making it a robust actuator for mid-range industrial linear motion.
This tie-rod cylinder has a body length A of 182 mm, resulting in a total extended length of approximately 952 mm. It includes an adjustable pneumatic cushion (28 mm length) at both ends to decelerate the piston smoothly, reducing end-of-stroke impact. The standard TPU seals provide an operating temperature range of -20 to +70 °C.

Where the Airtac SC80 Standard Cylinder SC80X770 Is Used
Material Transfer
Pushes or diverts boxes and components on a conveyor line, where a 770 mm stroke reaches across wide belt sections.
Press-Fit Assembly
Provides up to 4523 N of force at 0.9 MPa for inserting bearings, pins, or bushings into housings in a semi-automated fixture.
Bin Tipping
Actuates a tipping mechanism for bulk bins, using the long 770 mm stroke to achieve the necessary dump angle.
Is the Airtac SC80 Standard Cylinder SC80X770 the Right Cylinder?
Select the SC80 bore when your application needs a push force between 2513 N and 4523 N. If your load requires less force, stepping down to the SC63 bore provides 1559 N at 0.5 MPa. For higher force demands, the SC100 bore offers 3927 N at the same pressure. With a 770 mm stroke, the rod is significantly extended; ensure side loads are minimal or use an external guide rail to prevent rod bending and premature bearing wear.
For a correct replacement, match five key specifications: an 80 mm bore, a 770 mm stroke, PT3/8 port thread, the specific mounting accessory (this is a basic model without brackets), and the absence of a built-in magnet. This ensures dimensional and functional interchangeability with an existing AirTAC SC80X770 unit.
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 SC80X770 FAQ
The theoretical push force is 2513 N at 0.5 MPa and 4523 N at the maximum operating pressure of 0.9 MPa. The pull force on the retract stroke is slightly lower due to the rod area, measuring 2268 N at 0.5 MPa.
No, the SC80X770 is a double-acting cylinder and will not hold its position if air pressure is lost or the valve is centered. The piston can drift. For load holding without live pressure, you must add an external rod lock or a pilot-operated check valve.
