About the Airtac SC100 Standard Cylinder SC100X185
The SC100X185 is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, pairing a 100 mm bore with a 185 mm stroke. At 0.5 MPa it generates a push force of 3927 N and a pull force of 3681 N, rising to 7068 N push at the maximum operating pressure of 0.9 MPa. The 25 mm diameter piston rod and PT1/2 ports suit medium-to-heavy linear actuation tasks.
This model uses the standard TPU/NBR seal package for a working temperature range of -20 to +70 °C. The body length A is 188 mm, giving a total extended length of approximately 373 mm. The integrated adjustable air cushion, with a 29 mm cushion length, decelerates the piston smoothly at both ends of the stroke to reduce impact and noise.

Where the Airtac SC100 Standard Cylinder SC100X185 Is Used
Pallet Stop & Lift Gates
The 3927 N push force at 0.5 MPa reliably raises or stops heavy pallets on gravity roller conveyors. The adjustable cushion protects the end caps during frequent cycling.
Clamping & Press Fixtures
Delivers up to 7068 N at 0.9 MPa for holding large workpieces during welding or machining. The 185 mm stroke provides ample clearance for part loading and unloading.
Baler & Compactor Ejection
Suitable for ejecting compacted material bales in recycling equipment. The robust 25 mm rod and tie-rod construction handle the repetitive, high-thrust ejection cycle.
Is the Airtac SC100 Standard Cylinder SC100X185 the Right Cylinder?
Choose the SC100X185 when your application needs around 3900 N of push force from a compact tie-rod cylinder. If you require more force, stepping up to the SC125 bore provides 6136 N at 0.5 MPa; for less force, the SC80 bore delivers 2513 N. For strokes of 185 mm, the standard rod bearing provides good support, but always avoid direct side loading on the rod.
To ensure a correct replacement, match five key points: a 100 mm bore, 185 mm stroke, PT1/2 port thread, the specific mounting accessory (this is a basic body without brackets), and the magnet option (this model has no built-in magnet). The SC is a tie-rod cylinder and is dimensionally shorter than an ISO 15552 profile cylinder, so it is not a drop-in ISO interchange.
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 SC100X185 FAQ
At 0.7 MPa operating pressure, the SC100X185 produces a theoretical push force of 5497 N and a pull force of 3681 N on the retract stroke. The maximum push force at 0.9 MPa is 7068 N.
No. The AirTAC SC series is a tie-rod cylinder with a shorter overall body length than a comparable ISO 15552 profile cylinder. It only directly replaces another AirTAC SC tie-rod cylinder with the same 100 mm bore, 185 mm stroke, PT ports, and basic mounting configuration.
