About the Airtac SC80 Standard Cylinder SC80X770S
The SC80X770S is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, combining an 80 mm bore with a 770 mm stroke. It generates a push force of 2513 N at 0.5 MPa and up to 4523 N at 0.9 MPa, driven by a 25 mm diameter piston rod with an M20x1.5 male thread.
This model includes a built-in magnet (-S suffix), allowing direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors on the barrel for contactless position sensing. The cylinder body length is 182 mm, resulting in a total extended length of approximately 952 mm. It features adjustable pneumatic cushioning over a 28 mm stroke to decelerate the piston smoothly at end positions.

Where the Airtac SC80 Standard Cylinder SC80X770S Is Used
Material Handling Gates
The 770 mm stroke and 2513 N push force at 0.5 MPa suit diverting gates on wide conveyor lines, where the built-in magnet provides end-of-travel feedback to the PLC.
Long-Reach Part Transfer
Moves components between distant stations on assembly fixtures. The 25 mm rod and adjustable cushion handle the inertia of the extended load at speeds up to 800 mm/s.
Pallet Stop Deployment
Deploys heavy-duty pallet stops in logistics systems. The -S magnet confirms retracted and extended positions, ensuring the stop is clear before a pallet is released.
Is the Airtac SC80 Standard Cylinder SC80X770S the Right Cylinder?
For applications requiring less force, the 63 mm bore SC series offers 1559 N push at 0.5 MPa. If more force is needed, the 100 mm bore provides 3927 N at the same pressure. The 770 mm stroke is well within the 1500 mm maximum standard stroke for the 80 mm bore.
When replacing an existing cylinder, match five points: bore (80 mm), stroke (770 mm), port thread (PT1/4), mounting accessory (basic, no bracket), and the built-in magnet (-S). For a stroke of this length, avoid side loading the unsupported 25 mm rod; use an external linear guide or a guided cylinder if lateral forces are present to prevent rod bending and premature bearing wear.
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 SC80X770S FAQ
At the standard operating pressure of 0.5 MPa, the push force is 2513 N and the pull force is 2268 N. At the maximum operating pressure of0.9 MPa, the push force reaches 4523 N. The theoretical maximum force at1.0 MPa is 513 kgf.
Yes. The -S suffix denotes a built-in magnetic piston. You can clamp AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the barrel's sensor groove without any additional brackets.
