About the Airtac SC100 Standard Cylinder SC100X900STC
The SC100X900STC is a double-acting pneumatic cylinder delivering a substantial 3927 N of push force at 0.5 MPa, scaling up to 7068 N at the maximum operating pressure of 0.9 MPa. With a 100 mm bore and a 900 mm stroke, it uses a rigid 25 mm diameter piston rod and features an adjustable air cushion (29 mm length) to decelerate the piston smoothly at end-of-travel, reducing impact and noise.
This configuration includes a built-in magnet (-S suffix) for direct mounting of CMSG/DMSG/EMSG sensors, and a centre trunnion mount (TC suffix, part F-SC100TC) supplied with the TCM1 bracket, allowing the cylinder to pivot for swinging loads. The body length A is 188 mm, giving a total extended length of 1088 mm. It is a genuine AirTAC tie-rod cylinder, shorter than an ISO 15552 profile and not interchangeable with it.

Where the Airtac SC100 Standard Cylinder SC100X900STC Is Used
Long-Stroke Part Transfer
The 900 mm stroke and 3927 N push force efficiently transfer heavy components between distant conveyor stations or pallets in automated lines.
Pivoting Clamp Actuation
With the TC centre trunnion mount, this cylinder is ideal for heavy-duty pivoting clamps or welding fixtures that must swing into position and apply high force.
Bulk Material Gate Control
Uses the long stroke and high force to open and close large hopper gates or diverter chutes handling bulk aggregates or grain, with sensor confirmation via the built-in magnet.
Is the Airtac SC100 Standard Cylinder SC100X900STC the Right Cylinder?
Choose the SC100 for applications needing up to 3927 N at standard plant pressure. If your load requires less force, stepping down to an SC80 bore reduces push force to 2513 N at 0.5 MPa, saving space and air consumption. For higher demands, the SC125 bore provides 6136 N at the same pressure. At a 900 mm stroke, the extended rod is long; ensure the load is guided externally to prevent side-load bending on the 25 mm rod, which can damage the bearing and seals. For direct replacement, match bore (100 mm), stroke (900 mm), PT port thread, centre trunnion mount (TC), and the built-in magnet (-S).

- ✓ 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 SC100X900STC 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. The theoretical maximum force at 1.0 MPa is 801 kgf.
No. The SC100 is a standard double-acting cylinder and will drift or drop if pressure is exhausted or the directional valve is centered. To hold a load safely without live pressure, you must add an external rod brake, a mechanical lock, or a pilot-operated check valve.
