About the Airtac SC80 Standard Cylinder SC80X250SFB
The SC80X250SFB is an 80 mm bore, 250 mm stroke double-acting pneumatic cylinder from the AirTAC SC tie-rod series, factory-equipped with a built-in magnet and a rear rectangular flange (FB). It delivers a push force of 2513 N at 0.5 MPa and can reach 4523 N at the maximum operating pressure of 0.9 MPa, making it a strong mid-bore actuator for industrial linear motion.
The cylinder uses a 25 mm diameter piston rod with M20x1.5 male threads and PT3/8 ports. Its body length A is 182 mm, giving a total extended length of approximately 432 mm. The adjustable air cushion (28 mm length) decelerates the piston smoothly at stroke ends, protecting end caps and reducing impact noise in high-cycle applications.

Where the Airtac SC80 Standard Cylinder SC80X250SFB Is Used
Material Handling Pushers
The 2513 N push force at 0.5 MPa easily diverts cartons or tote bins on powered roller conveyors. The rear flange mount (FB) bolts directly to the conveyor frame end plate, providing rigid alignment for repetitive pushing.
Clamping & Fixturing
With 4523 N of clamping force available at 0.9 MPa and magnetic piston sensing, this cylinder confirms clamp engagement in automated welding or machining fixtures. The adjustable cushion prevents impact shock on delicate workpieces.
Grain Gate Actuation
The SC80X250SFB operates slide gates on silos or hoppers. The built-in magnet allows remote gate position feedback, while the tie-rod construction withstands dusty environments with proper air filtration.
Is the Airtac SC80 Standard Cylinder SC80X250SFB the Right Cylinder?
Select the SC80 when the 50 mm bore's 982 N push force (at 0.5 MPa) is insufficient, but a full 100 mm bore (3927 N) is oversized for the load. This 250 mm stroke is within the standard range for the 80 mm bore (max 1500 mm). For strokes above 300 mm with this 25 mm rod, evaluate side-load conditions; an external guide or guided cylinder is recommended to prevent rod bending and premature bearing wear.
To replace an existing cylinder, match five points exactly: 80 mm bore, 250 mm stroke, PT port thread, rear FB flange mounting (F-SC80FB), and the built-in magnet (-S suffix) for CMSG/DMSG/EMSG sensor compatibility. The SC is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders.
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 SC80X250SFB 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 reaches 4523 N. The theoretical maximum force at 1.0 MPa is 513 kgf.
Yes. The -S suffix in SC80X250SFB indicates a built-in magnet on the piston. This allows you to clamp AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the barrel tie-rods to detect piston position without external brackets.
