About the Airtac SC100 Standard Cylinder SC100X550TC
The SC100X550TC is a double-acting tie-rod cylinder delivering 3927 N of push force at 0.5 MPa (7068 N at the 0.9 MPa maximum operating pressure). With a 100 mm bore and 550 mm stroke, it uses a 25 mm diameter piston rod and PT1/2 ports, making it a robust choice for medium-to-heavy linear actuation tasks.
This model includes the TC centre trunnion mount, supplied with the TCM1 bracket (F-SC100TC), which allows the cylinder to pivot during operation and is ideal for swinging or articulating loads. The adjustable air cushion (29 mm) decelerates the piston smoothly at end-of-stroke, protecting the end caps and reducing noise.

Where the Airtac SC100 Standard Cylinder SC100X550TC Is Used
Conveyor Diverters
The 550 mm stroke and pivoting trunnion mount suit medium-reach diverter gates on packaging or sortation conveyors, handling product flow redirection reliably.
Clamping & Fixturing
Delivers 7068 N of clamping force at 0.9 MPa for heavy weld fixtures or machining jigs, with the trunnion allowing the cylinder body to self-align.
Agricultural Equipment
Operates chute controls or hopper doors on farming machinery, where the centre trunnion accommodates the arcing motion of the linkage.
Is the Airtac SC100 Standard Cylinder SC100X550TC the Right Cylinder?
Choose the SC100 when the 50 mm bore's 982 N push at 0.5 MPa is insufficient, but you do not yet need the 125 mm bore's 6136 N. For this 550 mm stroke, ensure the rod is not subjected to side loading; if the load is not guided, add an external linear guide or switch to a guided cylinder to prevent rod bending and premature seal wear. To replace an existing unit, match the 100 mm bore, 550 mm stroke, PT1/2 ports, TC centre trunnion mount, and confirm the magnet requirement.
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 SC100X550TC FAQ
At 0.5 MPa 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.
No, the SC100X550TC is a double-acting cylinder and will not hold position if pressure is lost or the valve is centred. The piston will drift. For load holding without live pressure, you must add a pilot-operated check valve or an external mechanical rod lock.
