About the Airtac SC50 Standard Cylinder SC50X145TC
The AirTAC SC50X145TC is a double-acting tie-rod cylinder delivering 982 N of push force at 0.5 MPa (1374 N at 0.7 MPa), ideal for medium-duty linear actuation. This 50 mm bore model features a 20 mm piston rod with M16x1.5 male threads and a 21 mm adjustable air cushion at each end, providing smooth deceleration across a 145 mm stroke.
Supplied with the TC centre trunnion mount and TCM1 bracket (F-SC50TC), this cylinder is ready for pivoting applications where the load swings through an arc. The body length A is 150 mm, giving a compact total extended length of approximately 295 mm. PT1/4 ports and TPU seals with a standard -20 to +70 °C range complete the build.

Where the Airtac SC50 Standard Cylinder SC50X145TC Is Used
Part Diverter Gates
The 145 mm stroke and centre trunnion mount allow the cylinder to pivot as it extends, smoothly pushing product from one conveyor lane to another in packaging and sortation systems.
Clamp & Fixture Actuation
With 1374 N of force at 0.7 MPa, this cylinder provides strong, repeatable clamping for welding fixtures, assembly jigs, and CNC workholding where the body needs to swing into position.
Damper & Linkage Control
The adjustable cushion and pivoting TC mount make this cylinder suitable for operating heavy dampers, louvers, or mechanical linkages that move through an arc, absorbing end-of-stroke shock.
Is the Airtac SC50 Standard Cylinder SC50X145TC the Right Cylinder?
Choose the SC50 bore when your application needs between 982 N (push at 0.5 MPa) and 1767 N (push at 0.7 MPa). If you require more force, step up to the SC63 bore, which offers 1559 N at 0.5 MPa; for lighter, faster moves, the SC40 bore provides 628 N at 0.5 MPa. The 145 mm stroke is well within the 1200 mm maximum standard stroke for this bore.
For a direct replacement, match five points: 50 mm bore, 145 mm stroke, PT1/4 port thread, TC centre trunnion mounting (includes TCM1 bracket), and the absence of a magnet. The centre trunnion allows the cylinder body to pivot, so ensure the mounting pins and bracket are correctly sized for the swinging load.
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 SC50X145TC FAQ
At the standard 0.5 MPa operating pressure, the push force is 982 N and the pull force is 825 N. At 0.7 MPa, push force increases to 1374 N. The theoretical maximum force at 1.0 MPa is 200 kgf (1960 N), but the recommended operating range is 0.15–1.0 MPa.
No. The SC series is a tie-rod cylinder with a shorter body length than a comparable ISO 15552 cylinder, so mounting dimensions and overall length will differ. It is a direct replacement only for another AirTAC SC50 tie-rod cylinder with matching stroke, PT ports, and TC centre trunnion mount.
