About the Airtac SC100 Standard Cylinder SC100X680S
The SC100X680S is a double-acting pneumatic cylinder delivering a substantial push force of 3927 N at 0.5 MPa, rising to 7068 N at the maximum operating pressure of 0.9 MPa. With a 100 mm bore and a 680 mm stroke, it features a 25 mm diameter piston rod and a 29 mm adjustable air cushion at each end to decelerate the moving mass smoothly.
This model includes a built-in magnet (-S suffix), allowing direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors on the barrel for non-contact position sensing. The standard PT1/2 ports and TPU seals with a -20 to +70 °C operating range make it a robust choice for general industrial automation tasks requiring a long, controlled linear stroke.

Where the Airtac SC100 Standard Cylinder SC100X680S Is Used
Material Transfer Gates
The 680 mm stroke and 3927 N force at 0.5 MPa are ideal for diverting heavy packages or pallets on wide conveyor lines, with the built-in magnet providing end-of-stroke confirmation to the PLC.
Heavy Part Clamping
Applies up to 7068 N of clamping force at 0.9 MPa for securing large weldments or castings in machining fixtures, where sensor feedback from the -S magnet ensures the clamp is fully engaged before the cycle starts.
Pallet Lift & Transfer
Provides a long, smooth lifting motion for heavy pallet lifts in automated storage systems. The adjustable cushioning protects the assembly from shock at the end of the 680 mm travel, even under full-speed operation.
Is the Airtac SC100 Standard Cylinder SC100X680S the Right Cylinder?
For applications needing more force, the SC125 series steps up to a 6136 N push at 0.5 MPa. If a shorter, more compact build is acceptable, the SC80 provides 2513 N at the same pressure. At a 680 mm stroke, the 25 mm rod is well-supported within the cylinder, but if the load is guided externally, ensure perfect alignment to prevent side-load bending on the rod.
To guarantee a direct replacement, match five key points: the 100 mm bore, the 680 mm stroke, the PT1/2 port thread, the built-in magnet for sensor compatibility, and the basic (footless) mounting configuration. This is a tie-rod cylinder, not an ISO 15552 profile, so dimensional interchangeability is limited to another AirTAC SC100 of the same stroke.
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 SC100X680S 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. These values are based on the 100 mm bore and 25 mm rod diameter.
No. The SC100X680S is a double-acting cylinder that requires continuous air pressure to maintain its position. If pressure is lost or the directional valve is centered, the piston rod will drift or drop under load. For load-holding, you must add an external rod brake, a mechanical lock, or a pilot-operated check valve.
