About the Airtac SC100 Standard Cylinder SC100X425TC
The SC100X425TC is a double-acting pneumatic cylinder delivering 3927 N of push force at 0.5 MPa (7068 N at 0.9 MPa), making it a strong mid-range actuator for industrial automation. Its 100 mm bore houses a 25 mm diameter piston rod with a 29 mm adjustable air cushion at each end, and the centre trunnion mount allows the cylinder to pivot during operation.
With a 425 mm stroke and a body length A of 188 mm, the total extended length reaches approximately 613 mm. The TC suffix supplies the F-SC100TC centre trunnion together with the TCM1 bracket, ready for pivoting installation. This genuine AirTAC SC series unit uses PT port threads and standard TPU seals for reliable service from -20 to +70 °C.

Where the Airtac SC100 Standard Cylinder SC100X425TC Is Used
Conveyor Diverter Gates
The 3927 N push force at 0.5 MPa and pivoting trunnion mount make this cylinder ideal for actuating heavy diverter gates on wide conveyor lines, where the cylinder body needs to swing through an arc.
Clamping & Fixturing
Delivers consistent, high clamping force for large weld fixtures or machining centres. The adjustable cushion decelerates the 25 mm rod smoothly, protecting tooling from impact at the end of the 425 mm stroke.
Press & Forming Assist
Use the SC100X425TC as a material handling pusher or stripping cylinder in light press operations. Its 7068 N thrust at 0.9 MPa handles tough ejection tasks, while the trunnion mount absorbs misalignment.
Is the Airtac SC100 Standard Cylinder SC100X425TC the Right Cylinder?
Choose the SC100 bore when your application needs roughly 3927 N at 0.5 MPa; if you can accept 2513 N, stepping down to an SC80 saves space and air consumption, while moving up to an SC125 provides 6136 N for heavier loads. For this 425 mm stroke, confirm that side loads are minimal or use an external guide rail—long unsupported strokes on a single rod can introduce bending moments that accelerate bearing wear.
When replacing an existing cylinder, match five points: 100 mm bore, 425 mm stroke, PT port thread, centre trunnion (TC) mounting with the TCM1 bracket, and no magnet. The SC series is a tie-rod design and is not dimensionally interchangeable with ISO 15552 profile 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 SC100X425TC FAQ
At the standard operating pressure of 0.5 MPa, this cylinder produces 3927 N extending (push) and 3681 N retracting (pull). At the maximum operating pressure of 0.9 MPa, the push force reaches 7068 N. The theoretical maximum at 1.0 MPa is 801 kgf.
No. The AirTAC SC series is a tie-rod cylinder with a shorter body length than an equivalent ISO 15552 profile cylinder, so mounting dimensions and overall length differ. It is a direct replacement only for another AirTAC SC100 tie-rod cylinder with matching bore, stroke, PT ports, and centre trunnion mount.
