About the Airtac SC50 Standard Cylinder SC50X1300STC
The SC50X1300STC is a double-acting pneumatic cylinder delivering 982 N of push force at 0.5 MPa, scaling to 1767 N at the maximum operating pressure of 0.9 MPa. With a 20 mm diameter piston rod and a 1300 mm stroke, this model is configured for long-reach actuation where a pivoting mount is essential.
This non-standard stroke cylinder features a built-in magnet for direct mounting of CMSG/DMSG/EMSG sensors and a centre trunnion (TC) mount, supplied with the TCM1 bracket. The adjustable air cushion (21 mm) decelerates the piston smoothly, while the PT1/4 port thread ensures reliable air supply.

Where the Airtac SC50 Standard Cylinder SC50X1300STC Is Used
Long-Stroke Material Handling
The 1300 mm stroke and 1767 N push force at 0.9 MPa efficiently transfer heavy totes or panels across wide conveyor gaps, with the centre trunnion allowing the cylinder to pivot as it actuates.
Automated Welding Fixtures
Magnetic piston sensors provide precise end-of-stroke confirmation for clamping large weldments, while the TC mount lets the cylinder swing into position in tight automated cells.
Vertical Lift Assistance
Ideal for raising and lowering platforms or hoods on industrial machinery, the adjustable cushioning ensures a soft stop under heavy, shifting loads at the top of the stroke.
Is the Airtac SC50 Standard Cylinder SC50X1300STC the Right Cylinder?
For applications needing more force, stepping up to the 63 mm bore provides 1559 N at 0.5 MPa. If a shorter, standard-stroke model is sufficient, the SC50X1200 is the maximum standard length for this bore. The 1300 mm stroke is non-standard and made-to-order.
At this stroke length, the 20 mm rod is susceptible to bending under side loads. An external linear guide or a guided cylinder is strongly recommended to protect the rod bearing and seals. For replacement, match the 50 mm bore, 1300 mm stroke, PT1/4 port thread, TC centre trunnion mount (F-SC50TC), and the integrated magnet (-S).
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 SC50X1300STC FAQ
At 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 increases to 1767 N. The theoretical maximum force at 1.0 MPa is 200 kgf.
To ensure a direct fit, verify five key points: a 50 mm bore, a 1300 mm stroke, a PT1/4 port thread, a centre trunnion (TC) mount with the TCM1 bracket, and a built-in magnet (-S) for sensor compatibility. This is a non-standard stroke, so confirm the overall extended length of approximately 280 mm (body) + 1300 mm (stroke).
