About the Airtac SC100 Standard Cylinder SC100X385
The AirTAC SC100X385 is a double-acting tie-rod cylinder delivering a substantial 3927 N of push force at 0.5 MPa, scaling up to 7068 N at the 0.9 MPa maximum operating pressure. Its 25 mm diameter piston rod and 29 mm adjustable air cushion are engineered for reliable deceleration of heavy payloads, making this 385 mm stroke unit a workhorse for demanding linear motion tasks.
With a compact body length of 188 mm, the SC100X385 fits into tighter machine envelopes than an equivalent ISO 15552 cylinder. The PT1/2 port threads provide ample flow for rapid cycling, while the standard TPU seals ensure consistent performance in ambient temperatures from -20 to +70 °C.

Where the Airtac SC100 Standard Cylinder SC100X385 Is Used
Pallet Transfer
Pushes heavy pallets or totes across roller conveyors in distribution centers, leveraging the 3927 N force at standard line pressure.
Press-Fit Assembly
Provides the 7068 N thrust at 0.9 MPa needed for pressing bearings or bushings into housings on automated assembly lines.
Grain Gate Actuation
Operates heavy slide gates on silos or hoppers, where the 25 mm rod withstands the abrasive, dusty environment.
Is the Airtac SC100 Standard Cylinder SC100X385 the Right Cylinder?
For applications requiring slightly less force, stepping down to an 80 mm bore SC80 series provides 2513 N at 0.5 MPa. If the 385 mm stroke generates significant side loading, an external guide rail or a guided cylinder configuration is strongly recommended to protect the rod bearing from bending stress. This model is a direct replacement for any AirTAC SC100X385 tie-rod cylinder matching the PT port, basic mount, and no-magnet 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 SC100X385 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 reaches 7068 N. The theoretical maximum force at 1.0 MPa is 801 kgf.
No, the SC100X385 is a double-acting cylinder and will not hold its position if pressure is exhausted or the directional valve is centered. For load-holding, you must add a pilot-operated check valve or an external mechanical rod brake.
