About the Airtac SC100 Standard Cylinder SC100X870S
The AirTAC SC100X870S is a double-acting tie-rod cylinder delivering a substantial push force of 3927 N at 0.5 MPa (7068 N at the 0.9 MPa maximum operating pressure). With an 870 mm stroke and a 25 mm diameter piston rod, it is built for linear tasks requiring a long, powerful reach.
This model features a built-in magnet (-S suffix), allowing CMSG, DMSG, or EMSG reed and solid-state sensors to be mounted directly on the barrel for precise, non-contact position sensing. The body length A is 188 mm, and the total extended length is approximately 1058 mm. Ports are PT1/2 with an M20x1.5 rod thread, and the adjustable pneumatic cushion (29 mm) ensures smooth deceleration at end-of-stroke.

Where the Airtac SC100 Standard Cylinder SC100X870S Is Used
Long-Reach Part Transfer
The 870 mm stroke and 3927 N force at 0.5 MPa move heavy components between distant conveyor stations. The built-in magnet provides sensor feedback for end-of-stroke confirmation in automated lines.
Automated Press Feed
Delivers a controlled 7068 N push at 0.9 MPa to advance large sheets or blanks into a stamping press. The adjustable cushion decelerates the high-inertia load quietly and reliably.
Pallet Layer Positioning
Positions a pallet layer forming head with a long vertical stroke. The tie-rod construction handles the repetitive cycling, and the magnetic piston enables programmable height verification.
Is the Airtac SC100 Standard Cylinder SC100X870S the Right Cylinder?
The SC100 bore provides 3927 N of push force at 0.5 MPa. If your application requires a more compact actuator, stepping down to the SC80 bore offers 2513 N at the same pressure. For significantly higher force, the SC125 bore delivers 6136 N. Always match the bore, 870 mm stroke, PT port thread, and the -S magnet option when replacing an existing cylinder.
For this 870 mm stroke, carefully evaluate side-loading conditions. A long, unsupported 25 mm rod is susceptible to bending under lateral forces. To ensure long seal life and prevent rod bearing damage, use an external linear guide or a guided cylinder to absorb any side loads, keeping the SC100 cylinder dedicated to pure axial thrust.
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 SC100X870S FAQ
The theoretical push force at 0.5 MPa is 3927 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 7068 N. The pull force on the retract stroke is 3681 N at 0.5 MPa due to the area of the 25 mm rod.
It is a direct dimensional match for any AirTAC SC100 tie-rod cylinder with an 870 mm stroke, PT1/2 ports, and a built-in magnet (-S suffix). It is not dimensionally interchangeable with ISO 15552 profile cylinders, as the SC series has a shorter overall body length.
