About the Airtac SC100 Standard Cylinder SC100X450N
The SC100X450N is a double-acting pneumatic cylinder with a 100 mm bore and 450 mm stroke, fitted with NBR (nitrile) seals for consistent performance in standard industrial environments. At 0.5 MPa operating pressure it generates 3927 N of push force and 3681 N on the pull stroke, while at the maximum operating pressure of 0.9 MPa the push thrust reaches 7068 N.
This tie-rod cylinder uses a 25 mm diameter piston rod with an M20x1.5 rod thread and PT1/2 port connections. The adjustable air cushion at each end provides a 29 mm deceleration zone, helping to reduce end-of-stroke impact. With a body length A of 188 mm, the total extended length is approximately 638 mm, making it a compact choice for medium-to-heavy linear actuation tasks.

Where the Airtac SC100 Standard Cylinder SC100X450N Is Used
Pallet & Case Handling
The 3927 N push force at 0.5 MPa easily lifts and transfers loaded pallets or heavy cases on packaging lines, where the 450 mm stroke provides ample reach for cross-pushing conveyors.
Heavy-Duty Clamping
Delivers up to 7068 N of clamping force at 0.9 MPa for CNC fixture tables and welding jigs, holding large fabrications securely during machining or assembly.
Press & Forming Tools
Suited to small hydraulic-press alternatives for punching, riveting, or forming operations, where the 100 mm bore provides the high force density needed in a compact tie-rod body.
Is the Airtac SC100 Standard Cylinder SC100X450N the Right Cylinder?
For applications needing slightly less force in the same form factor, the 80 mm bore SC80 series delivers 2513 N push at 0.5 MPa. If the 3927 N push force of this SC100X450N is marginal, stepping up to the 125 mm bore provides 6136 N at the same pressure. At 450 mm stroke, the 25 mm rod is well-supported inside the barrel, but any significant side load should be managed with an external linear guide or rod-alignment coupler to protect the rod bearing and piston seals.
When replacing an existing cylinder, match five key points: 100 mm bore, 450 mm stroke, PT1/2 port thread (this model retains the standard PT thread), the basic mounting configuration (no integral bracket), and the absence of a built-in magnet. The NBR seal material is suited to standard temperature ranges and lubricated or non-lubricated compressed air.
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 SC100X450N FAQ
At 0.5 MPa (approximately 5 bar) the cylinder produces 3927 N pushing force and 3681 N pulling force. At the maximum rated operating pressure of 0.9 MPa, the push force increases to 7068 N. The theoretical maximum force at 1.0 MPa is 801 kgf.
Yes. The NBR (nitrile) seals in the SC100X450N are compatible with both lubricated and non-lubricated compressed air filtered to 40 µm. If you switch from lubricated to dry air, no seal change is required, though residual oil may temporarily affect initial dry-running friction.
