About the Airtac SC100 Standard Cylinder SC100X350
The SC100X350 is a robust double-acting pneumatic cylinder delivering 3927 N of push force at 0.5 MPa (7068 N at 0.9 MPa). Its 100 mm bore and 350 mm stroke make it a strong choice for medium-to-heavy linear actuation tasks where a compact tie-rod design is preferred.
This model features a 25 mm diameter piston rod with M20x1.5 threads, PT1/2 ports, and a 29 mm adjustable air cushion at each end. The body length A is 188 mm, giving a total extended length of approximately 538 mm. It is a genuine AirTAC SC-series cylinder, factory-tested to 1.5 MPa proof pressure.

Where the Airtac SC100 Standard Cylinder SC100X350 Is Used
Conveyor Diverters
Pushes heavy packages or pallets off a main conveyor line with 3927 N of force at 0.5 MPa, handling the 350 mm reach needed for wide belt systems.
Press-Fit Assembly
Provides up to 7068 N at 0.9 MPa for pressing bushings or bearings into housings, with adjustable cushioning to soften the end-of-stroke impact.
Material Clamping
Delivers strong, consistent clamping force for CNC fixtures or welding jigs, holding large workpieces securely during machining.
Is the Airtac SC100 Standard Cylinder SC100X350 the Right Cylinder?
Select the SC100 when your application needs roughly 3900 N of force at standard shop air. If you require more force, step up to the SC125 (6136 N at 0.5 MPa); for a lighter, more compact solution, the SC80 provides 2513 N. Always match the bore, 350 mm stroke, PT1/2 port thread, and basic mounting when replacing an existing unit.
At 350 mm of stroke, the 25 mm rod is well-supported for axial loads, but any significant side loading will create a bending moment on the rod bearing. For non-axial loads, use an external guide rail or switch to a guided cylinder to prevent premature rod seal and bearing wear.
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 SC100X350 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, push force reaches 7068 N. The theoretical maximum at 1.0 MPa is 801 kgf.
No. The SC series is a tie-rod cylinder that is physically shorter than an ISO 15552 cylinder, so it is not dimensionally interchangeable. It directly replaces another AirTAC SC100 cylinder with the same 350 mm stroke, PT1/2 ports, and basic mounting.
