About the Airtac SC100 Standard Cylinder SC100X900
The SC100X900 is a double-acting tie-rod cylinder delivering 3927 N push force at 0.5 MPa (7068 N at 0.9 MPa). Its 25 mm diameter piston rod and 188 mm body length A provide a robust foundation for a 900 mm working stroke, giving a total extended length of approximately 1088 mm.
At 900 mm, this stroke is well within the 1500 mm maximum standard stroke for the 100 mm bore, so it ships as a standard catalog item. The adjustable pneumatic cushion at each end (29 mm cushion length) decelerates the piston smoothly, and the PT1/2 port supplies ample flow for the 3927 N push force class.

Where the Airtac SC100 Standard Cylinder SC100X900 Is Used
Pallet Handling & Lift
With 3927 N of push at 0.5 MPa, the SC100X900 raises and transfers palletized loads in distribution centers where a 900 mm vertical stroke is needed.
Heavy Part Transfer
Shifts large castings or fabrications between machining stations, using the full 900 mm reach to bridge conveyor gaps without intermediate stops.
Agricultural Gate Actuation
Opens and closes heavy silo gates or chute diverters, providing the sustained push force and long travel required in bulk material handling.
Is the Airtac SC100 Standard Cylinder SC100X900 the Right Cylinder?
For a step up in force, the SC125 bore provides 6136 N push at 0.5 MPa. If space is tighter and 2513 N suffices, the SC80 bore is a lighter alternative. At a 900 mm stroke, side-load management is critical—never allow the rod to take direct lateral force. Use an external guide rail or rod-alignment coupler to prevent bending stress on the 25 mm rod and premature bearing wear. When replacing, match bore (100 mm), stroke (900 mm), PT port thread, basic mount, and the absence of a magnet.
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 SC100X900 FAQ
At 0.7 MPa operating pressure, the SC100X900 generates 5497 N of push force and 3681 N of pull force on the retract stroke.
No. At 900 mm stroke with a 25 mm rod, side loads must be managed externally. Always install a guide rail or rod-alignment coupler to prevent rod bending and seal damage.
