About the Airtac SC50 Standard Cylinder SC50X170TC
The SC50X170TC is a double-acting pneumatic cylinder delivering 982 N of push force at 0.5 MPa and up to 1767 N at 0.9 MPa, making it a capable mid-range actuator for industrial tasks. Its 170 mm stroke sits comfortably within the 1200 mm maximum standard stroke for the 50 mm bore, and the 20 mm diameter piston rod provides solid column strength for linear pushing and clamping operations.
This model comes factory-equipped with a TC centre trunnion mount (including the TCM1 bracket, part code F-SC50TC), allowing the cylinder body to pivot during operation—ideal for swinging or articulating loads. The adjustable air cushion (21 mm length) decelerates the piston smoothly at both ends, reducing end-of-stroke impact and extending service life in high-cycle applications.

Where the Airtac SC50 Standard Cylinder SC50X170TC Is Used
Part Diverter Gates
The pivoting TC mount lets the cylinder swing a diverter gate on a conveyor line, routing packages or components between lanes with the 170 mm stroke providing ample travel.
Clamping Fixtures
Delivers 982 N of clamping force at 0.5 MPa to hold workpieces during machining or welding, with the adjustable cushion preventing vibration and part shift at clamp closure.
Bin Tippers
Pivots a small bin or hopper through its arc using the trunnion mount, dumping parts or bulk material at the end of the 170 mm stroke with controlled cushion deceleration.
Is the Airtac SC50 Standard Cylinder SC50X170TC the Right Cylinder?
Choose the SC50X170TC when your application needs around 982 N of force at standard shop air; if you require significantly more thrust, stepping up to the 63 mm bore provides 1559 N at the same 0.5 MPa pressure. The centre trunnion mount suits pivoting installations, but ensure the load is guided externally if side forces are present, as the tie-rod construction is designed for axial loads. For a direct replacement, match five attributes: 50 mm bore, 170 mm stroke, PT port thread, TC centre trunnion mounting, and confirm whether a magnet (-S) is needed for sensor mounting.
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 SC50X170TC FAQ
At 0.5 MPa the cylinder produces 982 N extending and 825 N retracting. 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 SC series is a tie-rod cylinder and is physically shorter than an ISO 15552 profile cylinder, so mounting dimensions and overall length will not match. It is a direct replacement only for another AirTAC SC50 tie-rod cylinder with matching bore, stroke, PT ports, and TC trunnion mount.
