About the Airtac SC100 Standard Cylinder SC100X20TC
The SC100X20TC is a double-acting pneumatic cylinder delivering 3927 N of push force at 0.5 MPa (7068 N at 0.9 MPa). Its 20 mm stroke is ideal for short-throw clamping, ejecting, or positioning tasks where a compact extended length is critical.
This model features a 25 mm diameter piston rod with M20x1.5 threads and PT3/8 ports. It is factory-configured with a centre trunnion (TC) mount, allowing the cylinder body to pivot during operation. The mounting kit includes the TCM1 trunnion bracket (order reference F-SC100TC).

Where the Airtac SC100 Standard Cylinder SC100X20TC Is Used
High-Force Clamping
Short 20 mm stroke with 7068 N thrust at 0.9 MPa securely holds heavy workpieces during machining or welding.
Compact Ejector
Pivots on the TC trunnion to eject parts from a die or fixture in a tight space, retracting fully to clear the next cycle.
Diverter Gate Actuator
Swings a small diverter gate on a conveyor line; the trunnion mount absorbs the arc motion without side-loading the rod.
Is the Airtac SC100 Standard Cylinder SC100X20TC the Right Cylinder?
Choose the SC100 bore when your application needs roughly 4000 N of force at standard plant pressure; for lighter actuation around 2500 N, step down to the SC80 bore (2513 N at 0.5 MPa). The 20 mm stroke keeps the overall length very short, but ensure your end stops can handle the full thrust.
To replace an existing cylinder, match five points: 100 mm bore, 20 mm stroke, PT3/8 port thread, centre trunnion (TC) mount, and the absence of a magnet. This is a tie-rod cylinder, not an ISO 15552 profile, so dimensional interchangeability is limited to other AirTAC SC100 tie-rod units.
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 SC100X20TC FAQ
At 0.7 MPa supply pressure, the SC100 bore generates 5497 N of push force. The pull force at the same pressure is 3681 N, accounting for the 25 mm rod area.
The SC100X20TC ships with the TC centre trunnion bracket. If you need foot or flange mounting, order the basic SC100X20 and add the required accessory separately (e.g., LB foot mount F-SC100LB or FA front flange F-SC100FA).
