About the Airtac SC100 Standard Cylinder SC100X630
The SC100X630 is a double-acting single-rod cylinder that generates 3927 N of push force at 0.5 MPa and up to 7068 N at the maximum operating pressure of 0.9 MPa. With a 100 mm bore and a 630 mm stroke, it is built for applications that require substantial linear force over a mid-to-long travel distance.
This tie-rod cylinder features a 25 mm diameter piston rod with M20x1.5 threads and PT1/2 pneumatic ports. The body length A is 188 mm, and the adjustable air cushion is 29 mm at each end, providing reliable end-of-stroke deceleration. The standard operating temperature range is -20 to +70 °C with the default TPU seals.

Where the Airtac SC100 Standard Cylinder SC100X630 Is Used
Pallet Stop & Lift Gates
Provides the high force needed to raise heavy pallet stops or lift gates on gravity and powered conveyor lines, controlling pallet flow in distribution centers.
Waste Compaction & Baling
Delivers up to 7068 N of push force at 0.9 MPa, making it suitable for driving the compaction plate in small-to-medium waste balers and recycling equipment.
Heavy-Duty Clamping Fixtures
Used in large welding jigs and machining fixtures to securely clamp heavy steel fabrications, where the 630 mm stroke provides ample clearance for part loading.
Is the Airtac SC100 Standard Cylinder SC100X630 the Right Cylinder?
Select the SC100X630 when your application needs approximately 4000 N of force at standard plant air pressure. If the load requires less force, stepping down to an 80 mm bore (2513 N at 0.5 MPa) can reduce air consumption and physical size. For higher force demands, a 125 mm bore (6136 N at 0.5 MPa) is the next logical step.
At a 630 mm stroke, the piston rod is fully supported at both ends only when fully retracted. For applications with any side load, an external guide or a guided cylinder configuration is strongly recommended to prevent rod bending and premature bearing wear. For a direct replacement, match the 100 mm bore, 630 mm stroke, PT1/2 port thread, and basic mounting configuration exactly.
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 SC100X630 FAQ
At 0.5 MPa, the push force is 3927 N and the pull force is 3681 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 7068 N. The theoretical maximum force at 1.0 MPa is 801 kgf.
No, the SC100X630 is a double-acting cylinder and will not hold its position if air pressure is lost or the directional valve is centered. The adjustable air cushion only decelerates the piston at the end of stroke. To hold a load safely without live pressure, you must add an external rod brake, a mechanical lock, or a pilot-operated check valve.
