About the Airtac SC100 Standard Cylinder SC100X440
The SC100X440 is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, combining a 100 mm bore with a 440 mm stroke. At 0.5 MPa it generates 3927 N pushing and 3681 N pulling, while at the maximum operating pressure of 0.9 MPa the push force reaches 7068 N — a class suited to medium-duty pressing, clamping, and lifting tasks.
This model uses a 25 mm diameter piston rod with an M20x1.5 male thread and PT1/2 port connections. The body length A is 188 mm, giving an approximate extended length of 628 mm. An adjustable pneumatic cushion (29 mm length) decelerates the piston at each end of stroke, reducing impact and noise. The standard TPU seals provide an operating temperature range of -20 to +70 °C.

Where the Airtac SC100 Standard Cylinder SC100X440 Is Used
Conveyor Divert & Stop
The 3927 N push force at 0.5 MPa is ideal for actuating heavy-duty conveyor gates, part stops, and diverters on packaging and logistics lines.
Press & Clamp Fixtures
Delivers up to 7068 N at 0.9 MPa for pneumatic clamping, light press-fit assembly, and holding workpieces during welding or machining operations.
Material Lift & Tilt
With a 440 mm stroke and 3681 N pull force, this cylinder can tilt heavy bins, raise scissor-lift tables, or actuate chutes in material handling systems.
Is the Airtac SC100 Standard Cylinder SC100X440 the Right Cylinder?
For applications needing slightly less force in a more compact envelope, the 80 mm bore SC80 series delivers 2513 N push at 0.5 MPa. If the load demands higher force, stepping up to the 125 mm bore SC125 series provides 6136 N at the same pressure. Always match replacement cylinders on five points: bore (100 mm), stroke (440 mm), port thread (PT1/2), mounting accessory (none — basic body), and magnet option (none).
At 440 mm stroke the 25 mm rod is long enough that side loads or off-centre mounting can cause rod bearing wear and bending. When the load is not guided externally, add an external linear guide or consider a guided-cylinder configuration to protect the rod and seals from premature failure.
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 SC100X440 FAQ
At 0.5 MPa the push force is 3927 N and pull force is 3681 N. At 0.7 MPa push reaches 5497 N, and at the maximum operating pressure of 0.9 MPa it delivers 7068 N push. The theoretical maximum at 1.0 MPa is 801 kgf.
No. The AirTAC SC series is a tie-rod cylinder with a shorter overall body length than an ISO 15552 profile cylinder, so it is not dimensionally interchangeable. Only replace with another AirTAC SC tie-rod cylinder of matching bore (100 mm), stroke (440 mm), port thread (PT1/2), mounting, and magnet option.
