About the Airtac SC50 Standard Cylinder SC50X100TC
The SC50X100TC is a double-acting pneumatic cylinder with a 50 mm bore and 100 mm stroke, factory-equipped with a centre trunnion (TC) mount for pivoting applications. At 0.5 MPa it produces 982 N of push force and 825 N on the retract, making it a capable mid-range actuator for swinging or rotating loads.
This model uses a 20 mm diameter piston rod with an M16x1.5 male thread and PT1/4 ports. The adjustable air cushion (21 mm length) decelerates the piston smoothly at end of stroke, while the TC mount, supplied with the TCM1 bracket, allows the cylinder body to pivot as the load arcs. Standard TPU seals suit ambient temperatures from -20 to +70 °C.

Where the Airtac SC50 Standard Cylinder SC50X100TC Is Used
Clamping & Fixturing
The 982 N push force at 0.5 MPa is ideal for pneumatic toggle clamps and welding fixtures where the cylinder body needs to pivot on a trunnion mount to follow the clamp arm arc.
Part Diverter Gates
With the TC centre trunnion, this cylinder can swing a diverter gate on a conveyor line. The 100 mm stroke provides enough angular travel for reliable product sorting in packaging systems.
Machine Guard Actuation
Operate a pivoting safety guard or interlock door. The trunnion mount lets the cylinder body rotate as the guard opens and closes, while the cushioned end-of-stroke prevents slamming.
Is the Airtac SC50 Standard Cylinder SC50X100TC the Right Cylinder?
Choose the SC50 bore when your application needs roughly 1000 N of push force at typical plant pressure; stepping down to a 40 mm bore drops force to 628 N, while stepping up to 63 mm raises it to 1559 N at the same 0.5 MPa. The 100 mm stroke is a standard length well within the 1200 mm maximum for this bore.
For replacement, match five key points: 50 mm bore, 100 mm stroke, PT1/4 ports, centre trunnion (TC) mounting with the F-SC50TC bracket, and no built-in magnet. The SC is a tie-rod cylinder 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 SC50 Standard Cylinder SC50X100TC FAQ
At the standard operating pressure of 0.5 MPa, the push force is 982 N and the pull force is 825 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 1767 N. The theoretical maximum at 1.0 MPa is 200 kgf.
No. The AirTAC SC series is a tie-rod cylinder with a shorter overall body length than an ISO 15552 profile cylinder. The mounting dimensions and tie-rod centres differ. For a direct replacement, match another AirTAC SC tie-rod cylinder with the same bore, stroke, port thread, and TC centre trunnion mount.
