About the Airtac SC80 Standard Cylinder SC80X925S
The SC80X925S is a double-acting pneumatic cylinder delivering 2513 N push force at 0.5 MPa (4523 N at 0.9 MPa) from an 80 mm bore. With a 925 mm stroke and a 25 mm diameter piston rod, this tie-rod actuator suits long linear movements in material handling and automation. Its built-in magnet allows CMSG/DMSG/EMSG sensors to clamp directly onto the barrel for non-contact position sensing.
This model features adjustable pneumatic cushioning at both ends (28 mm cushion length) to decelerate the piston smoothly, reducing end-of-stroke impact. The body length A is 182 mm, giving an extended length of approximately 1107 mm. Ports are PT3/8, and the standard TPU seals provide an operating range of -20 to +70 °C.

Where the Airtac SC80 Standard Cylinder SC80X925S Is Used
Long-Stroke Part Transfer
Moves components 925 mm between conveyor lines or workstations. The built-in magnet enables end-of-stroke and mid-stroke position confirmation via barrel-mounted sensors.
Pallet Dispensing & Staging
Pushes pallets or totes across roller beds in logistics hubs. The 2513 N force at 0.5 MPa handles heavy stacked loads with smooth, adjustable cushioning.
Automated Gluing & Assembly
Extends a dispensing head or pressing tool over a long 925 mm reach. Sensor feedback from the integrated magnet ensures precise cycle initiation for consistent bond lines.
Is the Airtac SC80 Standard Cylinder SC80X925S the Right Cylinder?
For applications needing less force, the 63 mm bore SC63 series offers 1559 N at 0.5 MPa. If higher force is required, step up to the 100 mm bore SC100 series providing 3927 N at the same pressure. This 925 mm stroke is within the 1500 mm maximum standard stroke for the 80 mm bore.
At this stroke length, the 25 mm rod is susceptible to bending under side loads. Always guide the load externally with linear rails or rods, or consider a guided cylinder assembly. For direct replacement, match bore (80 mm), stroke (925 mm), PT3/8 port thread, the built-in magnet (-S suffix), and the basic mounting 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 SC80X925S FAQ
At 0.5 MPa the cylinder pushes with 2513 N. At the common 0.7 MPa line pressure it delivers 3518 N, and at the maximum operating pressure of 0.9 MPa it reaches 4523 N. Pull force on the retract stroke is 2268 N at 0.5 MPa due to the rod area.
Yes. The -S suffix indicates a built-in magnet around the piston, so AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors clip directly onto the tie-rod barrel to detect piston position without additional brackets.
