About the Airtac SC100 Standard Cylinder SC100X850STC
The SC100X850STC is a double-acting pneumatic cylinder delivering a substantial 3927 N push force at 0.5 MPa, rising to 7068 N at the maximum operating pressure of 0.9 MPa. With an 850 mm stroke and a 25 mm diameter piston rod, this model is built for applications requiring a long, powerful linear movement. The built-in magnet allows direct mounting of CMSG/DMSG/EMSG sensors for precise position feedback.
This configuration includes a centre trunnion (TC) mount, supplied with the TCM1 bracket (F-SC100TC), allowing the cylinder to pivot during operation—ideal for swinging or articulating loads. The body length A is 188 mm, making the total extended length approximately 1038 mm. It uses a PT1/2 port and an M20x1.5 rod thread, with an adjustable air cushion of 29 mm to decelerate the piston smoothly at the end of its travel.

Where the Airtac SC100 Standard Cylinder SC100X850STC Is Used
Material Handling & Sorting
Pivoting diverters and long-stroke pushers on conveyor lines use the 850 mm reach and trunnion mount to sweep products into different lanes.
Welding & Clamping Fixtures
The high clamp force at 0.9 MPa and sensor-ready magnet make it suitable for heavy-duty welding jigs where position confirmation is critical for safety.
Agricultural Machinery
Controls chutes, gates, or hopper doors on large equipment, with the centre trunnion allowing the cylinder body to pivot as the mechanism arcs.
Is the Airtac SC100 Standard Cylinder SC100X850STC the Right Cylinder?
For applications needing slightly less force, consider stepping down to the 80 mm bore (2513 N at 0.5 MPa). If your load requires a higher force margin, the 125 mm bore provides 6136 N at the same pressure. Always ensure the mounting style matches your machine's pivot axis—this TC centre trunnion is perfect for loads that need to arc. For a direct replacement, match the 100 mm bore, 850 mm stroke, centre trunnion mount, PT port thread, and the built-in magnet (-S) feature.
With an 850 mm stroke, the piston rod has significant unsupported length when extended. To prevent rod bending or bearing damage from side loads, it is critical to guide the load externally with a linear rail or rod guide. Never rely on the cylinder's rod bearing alone to support a heavy or off-centre load at full extension.
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 SC100X850STC FAQ
At the standard 0.5 MPa operating pressure, 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 at 1.0 MPa is 801 kgf.
No. As a standard double-acting cylinder, the SC100X850STC will drift or drop if air pressure is exhausted or the directional valve is centered. The adjustable air cushion only decelerates the piston at the stroke end to reduce impact; it is not a locking or holding brake. For load holding without live pressure, you must add an external rod lock or a pilot-operated check valve.
