About the Airtac SC100 Standard Cylinder SC100X620
The AirTAC SC100X620 is a double-acting tie-rod cylinder delivering a substantial 3927 N push force at 0.5 MPa (7068 N at 0.9 MPa). With a 100 mm bore and 620 mm stroke, it is built for medium-to-heavy linear actuation tasks where a robust, repairable cylinder is preferred over a disposable profile unit.
This model uses a 25 mm diameter piston rod with M20x1.5 threads and PT1/2 ports. The total extended body length is approximately 808 mm (188 mm body length A plus 620 mm stroke). The adjustable air cushion (29 mm length) decelerates the piston smoothly at each end of travel, protecting end caps from impact damage.

Where the Airtac SC100 Standard Cylinder SC100X620 Is Used
Press & Clamping Fixtures
The 3927 N push force at 0.5 MPa makes this cylinder ideal for pneumatic toggle clamps, assembly presses, and holding fixtures where consistent clamping pressure is critical.
Material Handling Gates
Use the 620 mm stroke to operate diverter gates or stoppers on wide conveyor lines, providing reliable actuation for sorting and routing packages or bulk materials.
Heavy-Duty Lifting & Tipping
With 3681 N pull force, it can tip heavy bins or lift moderate loads in scissor-lift tables, provided external guides manage the off-axis weight during the full 620 mm travel.
Is the Airtac SC100 Standard Cylinder SC100X620 the Right Cylinder?
For applications needing more force, step up to the SC125 bore which provides 6136 N at 0.5 MPa. If a shorter, more compact cylinder is acceptable, the SC80 bore delivers 2513 N at the same pressure. At a 620 mm stroke, the 25 mm rod is well within the standard stroke limit of 1500 mm, but any significant side load requires an external guide rail or rod support to prevent bearing wear and rod bending.
When replacing an existing cylinder, match five key points: 100 mm bore, 620 mm stroke, PT1/2 port thread, basic mounting (no integral bracket), and the absence of a built-in magnet. This SC100X620 is a direct replacement for another AirTAC SC100X620 tie-rod cylinder with the same configuration.
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 SC100X620 FAQ
At the standard operating pressure of 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 SC100X620 is a standard double-acting cylinder and will not hold its position if air pressure is lost or the directional valve is centered. The piston will drift or drop under load. To safely hold a load or position without live pressure, you must add an external rod lock, a mechanical brake, or a pilot-operated check valve.
