About the Airtac SC100 Standard Cylinder SC100X345S
The SC100X345S is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, combining a 100 mm bore with a 345 mm stroke. At 0.5 MPa operating pressure it generates a push force of 3927 N and a pull force of 3681 N, scaling up to 7068 N of push thrust at the maximum 0.9 MPa working pressure. The built-in magnet (denoted by the -S suffix) allows direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors on the barrel for contactless end-of-stroke detection.
This model uses a 25 mm diameter piston rod with an M20x1.5 male thread and PT1/2 port connections. The total extended body length is approximately 533 mm, calculated from the 188 mm base body length plus the 345 mm stroke. The adjustable air cushion at each end, with a 29 mm cushion length, decelerates the piston smoothly to reduce impact noise and mechanical stress. As a genuine AirTAC component, it is manufactured with a TPU/NBR seal package rated for -20 to +70 °C and filtered air at 40 µm.

Where the Airtac SC100 Standard Cylinder SC100X345S Is Used
Pallet Stop & Lift Gates
The 3927 N push force at 0.5 MPa easily raises or stops heavy pallets on conveyor lines. The built-in magnet provides reliable end-of-stroke feedback to the PLC for high-speed sortation systems.
Clamping & Assembly Presses
Delivers up to 7068 N of clamping force at 0.9 MPa for holding large workpieces during welding or machining. Magnetic sensors confirm jaw position before the cycle starts, enhancing safety.
Heavy-Duty Material Pushers
Ideal for pushing heavy bins or metal sheets off a production line. The 25 mm rod and tie-rod construction handle repetitive impact loads, while the adjustable cushion smooths the motion of high-inertia loads.
Is the Airtac SC100 Standard Cylinder SC100X345S the Right Cylinder?
Choose the SC100X345S for applications requiring a strong push force in the 3900–7100 N range with integrated position sensing. If your load demands more force, stepping up to the SC125 bore provides 6136 N at 0.5 MPa; for a lighter, more compact solution, the SC80 bore delivers 2513 N at the same pressure. The built-in magnet saves space and installation time compared to externally mounted limit switches.
For this 345 mm stroke, ensure the rod is not subjected to significant side loading. Long, unsupported piston rods can bend under lateral forces, causing premature bearing wear and seal failure. If side load is unavoidable, use an external linear guide or a guided cylinder variant to absorb the bending moment. When replacing an existing cylinder, match all five critical points: 100 mm bore, 345 mm stroke, PT port thread, the built-in magnet (-S), and your required mounting accessory.
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 SC100X345S FAQ
At the standard 0.5 MPa operating pressure, the push force is 3927 N and the pull force is 3681 N. At the maximum 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 -S suffix indicates a built-in magnet in the piston. This allows you to clamp compatible AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the cylinder barrel's tie-rod slots to detect piston position without external brackets.
