About the Airtac SC100 Standard Cylinder SC100X425
The SC100X425 is a double-acting tie-rod cylinder with a 100 mm bore and a 425 mm stroke, generating a push force of 3927 N at 0.5 MPa (up to 7068 N at 0.9 MPa). Its 25 mm diameter piston rod and 29 mm adjustable air cushion provide reliable deceleration for mid-stroke positioning tasks.
This genuine AirTAC SC cylinder uses a PT1/2 port and operates on filtered air from 0.15 to 1.0 MPa. With a body length A of 188 mm, the total extended length is approximately 613 mm, making it a compact choice for pressing, clamping, and material handling where a 100 mm bore is needed.

Where the Airtac SC100 Standard Cylinder SC100X425 Is Used
Heavy Clamping Fixtures
The 3927 N push force at 0.5 MPa securely holds large workpieces during machining or welding, with adjustable cushioning to reduce impact at the end of the 425 mm stroke.
Pallet Stop & Transfer
Stops and transfers heavy pallets on conveyor lines. The 25 mm rod and tie-rod construction handle repetitive impact, while the 425 mm stroke provides ample reach across wide conveyors.
Waste Compaction
Delivers up to 7068 N at 0.9 MPa for compacting cardboard, textiles, or recyclables. The 100 mm bore provides the high force density needed in compact baling equipment.
Is the Airtac SC100 Standard Cylinder SC100X425 the Right Cylinder?
Select the SC100X425 when your application needs around 4000 N of force at standard plant pressure. If you require less force, the SC80 bore delivers 2513 N push at 0.5 MPa in a lighter package; for heavier work, the SC125 bore provides 6136 N. At a 425 mm stroke, ensure the rod is not subjected to side loads—long unsupported rods can bend under lateral force. Use an external guide or a guided cylinder if side loading is present.
For direct replacement, match five points: 100 mm bore, 425 mm stroke, PT1/2 port thread, basic mounting (no bracket), and no magnet. This model uses standard TPU seals and PT threads. If your original cylinder has a magnet or a different mount, specify the corresponding suffix code.
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 SC100X425 FAQ
At 0.7 MPa (7 bar) the SC100 bore generates 5497 N of push force and 3681 N of pull force. The maximum operating force at 0.9 MPa is 7068 N push.
No. The SC series is a tie-rod cylinder and is shorter than an ISO 15552 profile cylinder, so it is not dimensionally interchangeable. Only replace another AirTAC SC (or equivalent tie-rod) cylinder with matching bore, stroke, port thread, mounting, and magnet option.
