About the Airtac SC100 Standard Cylinder SC100X850SFB
The SC100X850SFB is a double-acting pneumatic cylinder delivering 3927 N push force at 0.5 MPa (7068 N at 0.9 MPa). Its 100 mm bore and 850 mm stroke suit medium-to-heavy linear actuation tasks where a long working reach is required without stepping up to a larger frame size.
This model includes a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors, and an FB rear rectangular flange (F-SC100FB) for rigid cap-end mounting. The 25 mm diameter piston rod and 29 mm adjustable air cushion manage end-of-stroke deceleration, while the PT1/2 port supplies ample flow for the 100 mm bore.

Where the Airtac SC100 Standard Cylinder SC100X850SFB Is Used
Long-Reach Part Transfer
The 850 mm stroke moves parts between distant conveyor lanes or workstations. The FB rear flange keeps the cylinder body stable during full extension.
Press-Frame Actuation
With 7068 N of thrust at 0.9 MPa, this cylinder handles pressing, clamping, or forming operations in dedicated fixture frames.
Palletising Pushers
Pushes boxes or layers onto pallets. The magnet allows end-of-stroke confirmation sensors, critical for automated stacking sequences.
Is the Airtac SC100 Standard Cylinder SC100X850SFB the Right Cylinder?
Choose the SC100 bore when your application needs roughly 4000 N of push at standard plant pressure; the next step down is the SC80 (2513 N at 0.5 MPa), and the step up is the SC125 (6136 N at 0.5 MPa). At 850 mm stroke, the unsupported rod length is significant—side loads or off-centre tooling can bend the 25 mm rod or wear the bearing. Use an external guide rail or a guided-cylinder solution if the load is not perfectly axial.
For direct replacement, match five points: 100 mm bore, 850 mm stroke, PT1/2 port thread, FB rear flange mounting, and the -S magnet for sensor compatibility. The SC series is a tie-rod cylinder; it 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 SC100 Standard Cylinder SC100X850SFB FAQ
At 0.5 MPa, push force is 3927 N and pull force is 3681 N. At the maximum operating pressure of 0.9 MPa, push force reaches 7068 N. The theoretical maximum at 1.0 MPa is 801 kgf.
No. The SC series is a double-acting cylinder and does not lock or hold position when pressure is lost or the valve centres. The piston will drift. For load holding, add an external rod brake, mechanical lock, or pilot-operated check valve.
