About the Airtac SC80 Standard Cylinder SC80X860SN
The SC80X860SN is an 80 mm bore double-acting pneumatic cylinder with an extended 860 mm stroke, providing a push force of 2513 N at 0.5 MPa and up to 4523 N at the maximum operating pressure of 0.9 MPa. This model features a 25 mm diameter piston rod with M20x1.5 male threads and PT3/8 port connections, making it a robust choice for medium-duty linear actuation tasks requiring a long reach.
Equipped with a built-in magnet (suffix -S), the cylinder barrel accepts CMSG, DMSG, or EMSG reed and solid-state sensors for non-contact position feedback. The NBR seal variant (suffix -N) is standard for general industrial air, and the adjustable pneumatic cushion at each end decelerates the 28 mm cushion stroke to reduce end-of-travel impact without any mechanical locking function.

Where the Airtac SC80 Standard Cylinder SC80X860SN Is Used
Long-Reach Part Transfer
The 860 mm stroke moves components between widely spaced conveyor lanes or workstations. The built-in magnet confirms end-of-stroke position to prevent cycle-start errors.
Pallet Dispenser Pusher
Pushes empty pallets from a stack into a conveyor line. The 2513 N force at 0.5 MPa handles heavy wooden pallets, and the external guide requirement ensures straight travel under offset loads.
Automated Gluing or Welding Slide
Carries a glue head or spot-welding gun along a long linear path. Sensor feedback from the -S magnet confirms retraction before the next cycle, preventing tool collisions.
Is the Airtac SC80 Standard Cylinder SC80X860SN the Right Cylinder?
For an 80 mm bore at 0.5 MPa, the push force is 2513 N. If your load requires more force, stepping up to the 100 mm bore provides 3927 N at the same pressure; if you need less force and a lighter assembly, the 63 mm bore delivers 1559 N. At 860 mm, this stroke is well within the 1500 mm maximum standard stroke for the SC80 series, so it is a standard production length.
This long-stroke cylinder generates significant bending moment on the rod bearing if side loads are present. For strokes over 300 mm, always guide the load externally with linear rails or rods, or consider a guided cylinder variant to protect the rod and bearing from premature wear. When replacing an existing unit, match five points: 80 mm bore, 860 mm stroke, PT3/8 port thread, the built-in magnet (-S), and the basic mounting style.
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 SC80X860SN FAQ
At 0.5 MPa, it pushes with 2513 N and pulls with 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 SC80X860SN is a double-acting cylinder and will drift or drop if air pressure is exhausted or the directional valve is centered. The adjustable air cushion only decelerates the piston at stroke end; it does not lock or hold the load. Use a pilot-operated check valve or external rod lock for load-holding applications.
