About the Airtac SC100 Standard Cylinder SC100X900S
The SC100X900S is a double-acting pneumatic cylinder delivering a substantial 3927 N 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, this model features a 25 mm diameter piston rod and a body length A of 188 mm, making it a robust choice for long linear movements in industrial automation.
This variant includes a built-in magnet (-S suffix), allowing easy integration of CMSG, DMSG, or EMSG reed and solid-state sensors directly onto the tie-rod barrel for precise end-of-stroke or mid-stroke position sensing. The adjustable pneumatic cushion (29 mm length) decelerates the piston smoothly at both ends, protecting the end caps during high-speed operation.

Where the Airtac SC100 Standard Cylinder SC100X900S Is Used
Long-Stroke Material Handling
Ideal for pusher or diverter stations on conveyor lines, where the 900 mm stroke moves products across wide belts. The built-in magnet enables precise position confirmation at each end of the long travel.
Automated Press Feeding
Delivers the high force needed to push heavy blanks or sheets into a stamping press. The adjustable cushion absorbs the kinetic energy of the heavy load at the end of the rapid 900 mm stroke.
Pallet Layer Forming
Used in palletizing systems to push a full layer of boxes or bags onto a pallet stack. The 3927 N force at standard line pressure handles the cumulative weight of a complete product layer.
Is the Airtac SC100 Standard Cylinder SC100X900S the Right Cylinder?
For applications requiring slightly less force, consider stepping down to the 80 mm bore SC80 series, which provides 2513 N at 0.5 MPa. For heavier loads, the 125 mm bore SC125 series offers 6136 N at the same pressure. At a 900 mm stroke, the 25 mm rod is long and unsupported; any significant side loading will create a bending moment on the rod bearing. To ensure long service life, guide the load externally with a linear rail or rod guide, or use a guided cylinder variant, especially in vertical or offset-load applications.
When replacing an existing unit, match these five points to ensure compatibility: 100 mm bore, 900 mm stroke, PT port thread, the basic mounting configuration (no integrated bracket), and the built-in magnet for sensor mounting.
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 SC100X900S FAQ
At 0.7 MPa (7 bar) operating pressure, this 100 mm bore cylinder generates a push force of 5497 N and a pull force of 3681 N. The maximum theoretical force at 1.0 MPa is 801 kgf.
No. The SC100X900S is a double-acting cylinder and will not hold its position if air pressure is exhausted or lost. The piston can drift or drop under load. For load-holding safety, you must add an external mechanical rod lock, a pilot-operated check valve, or use a rod brake.
