About the Airtac SC100 Standard Cylinder SC100X435
The AirTAC SC100X435 is a double-acting single-rod pneumatic cylinder delivering 3927 N of push force at 0.5 MPa (7068 N at 0.9 MPa). With a 100 mm bore and 435 mm stroke, it uses a 25 mm diameter piston rod and PT1/2 ports for reliable high-flow actuation in clamping, pressing, and material-handling systems.
This tie-rod cylinder features an adjustable pneumatic cushion (29 mm length) to decelerate the piston smoothly at stroke ends. The body length A is 188 mm, giving an extended length of approximately 623 mm. It operates on filtered air from 0.15 to 1.0 MPa across a temperature range of -20 to +70 °C with standard TPU seals.

Where the Airtac SC100 Standard Cylinder SC100X435 Is Used
Heavy-Duty Clamping
Generates up to 7068 N of clamping force at 0.9 MPa, ideal for holding large workpieces in CNC machining centres and welding fixtures.
Pallet Stop & Transfer
The 435 mm stroke and 3927 N push at 0.5 MPa provide ample power and reach for stopping or transferring heavy pallets on roller conveyors.
Industrial Compaction
Suited to waste compaction or baling equipment where a long, powerful stroke is needed to compress materials into a dense form.
Is the Airtac SC100 Standard Cylinder SC100X435 the Right Cylinder?
For applications needing more force, stepping up to the SC125 bore provides 6136 N at 0.5 MPa. If a shorter, more compact cylinder is acceptable, the SC80 delivers 2513 N at the same pressure. At a 435 mm stroke, the 25 mm rod is robust, but sustained side loads should be managed with an external guide or linear rail to prevent rod bearing wear and bending.
When replacing this cylinder, match five key points: 100 mm bore, 435 mm stroke, PT1/2 port thread, basic (no bracket) mounting, and the absence of a built-in magnet. The SC100X435 is a genuine AirTAC tie-rod cylinder, not an ISO 15552 profile design, so dimensional interchangeability is limited to other AirTAC SC100 series cylinders.
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 SC100X435 FAQ
At 0.5 MPa, push force is 3927 N and pull force is 3681 N. At the maximum operating pressure of 0.9 MPa, push force reaches 7068 N. The theoretical maximum force at 1.0 MPa is 801 kgf.
No. The SC series is a tie-rod cylinder and is physically shorter than an ISO 15552 cylinder of the same bore and stroke. It is a direct replacement only for another AirTAC SC100 series cylinder with matching bore, stroke, PT1/2 ports, and basic mounting.
