About the Airtac SC100 Standard Cylinder SC100X680
The AirTAC SC100X680 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 a 680 mm stroke, this model is built for heavy linear actuation tasks requiring a long travel distance. The 25 mm diameter piston rod and PT1/2 ports ensure robust fluid flow and mechanical strength.
This cylinder features an adjustable pneumatic cushion (29 mm length) to decelerate the piston smoothly at stroke ends, reducing impact and noise. The body length A is 188 mm, making the total extended length approximately 868 mm. It operates on filtered air from 0.15 to 1.0 MPa within a standard temperature range of -20 to +70 °C using TPU seals.

Where the Airtac SC100 Standard Cylinder SC100X680 Is Used
Pallet Transfer Systems
Moves heavy pallets across transfer stations with the 3927 N push force at 0.5 MPa, ensuring reliable indexing over the 680 mm stroke.
Heavy Press Feed
Feeds large sheet metal blanks into stamping presses, utilizing the 7068 N maximum thrust at 0.9 MPa for consistent material positioning.
Bin Tipping Mechanisms
Actuates large industrial bin tippers, providing the long 680 mm travel and high force needed to dump heavy bulk materials.
Is the Airtac SC100 Standard Cylinder SC100X680 the Right Cylinder?
Select the SC100X680 when your application demands a push force around 3927 N at 0.5 MPa. If you need a higher force class, stepping up to the SC125 bore provides 6136 N at the same pressure. For lower force requirements, the SC80 bore offers 2513 N. Always match replacement cylinders by bore, stroke, port thread (PT), mounting accessory, and magnet option.
For this 680 mm stroke, carefully evaluate side-loading conditions. Long, unsupported piston rods are susceptible to bending under radial forces. To prevent rod bearing damage and ensure linear motion integrity, use an external guide rail system or a guided cylinder configuration whenever side loads are present.
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 SC100X680 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.
No. The SC100X680 is a double-acting cylinder and will not hold its position if air pressure is exhausted or lost. The piston will drift or drop. For load holding without live pressure, you must add an external mechanical lock, a rod brake, or a pilot-operated check valve.
