About the Airtac SC50 Standard Cylinder SC50X1280S
The AirTAC SC50X1280S is a double-acting tie-rod cylinder with a 50 mm bore and an extended 1280 mm stroke, built with a factory-installed magnet for direct mounting of CMSG/DMSG/EMSG sensors. This model generates 982 N of push force at 0.5 MPa and reaches 1767 N at the maximum operating pressure of 0.9 MPa, driven by a 20 mm diameter piston rod with M16x1.5 male threads.
With a body length A of 150 mm, the total extended length is approximately 1430 mm. The adjustable air cushion (21 mm length) decelerates the piston smoothly at both ends. This is a non-standard stroke exceeding the 1200 mm maximum for 50 mm bore, confirming a made-to-order configuration for applications needing extra-long linear travel.

Where the Airtac SC50 Standard Cylinder SC50X1280S Is Used
Long-Stroke Material Pusher
The 1280 mm reach with sensor feedback reliably pushes large panels or boxes across wide conveyor transfer stations, with the magnet confirming end-of-stroke position.
Automated Glue Applicator
Delivers a consistent 1767 N force at 0.9 MPa to depress a glue dispensing head over an extended 1280 mm linear path, ideal for long bead applications in packaging lines.
Vertical Pallet Stop
Raises or lowers a heavy pallet stop gate with 982 N at 0.5 MPa. The built-in magnet enables interlock signals to confirm the gate is fully retracted before traffic proceeds.
Is the Airtac SC50 Standard Cylinder SC50X1280S the Right Cylinder?
Select the SC50 when the 40 mm bore’s 628 N push at 0.5 MPa is marginal and the 63 mm bore’s 1559 N is oversized for the load. For this 1280 mm stroke, the long unsupported rod is vulnerable to bending under side load; always guide the load externally or pair the cylinder with a linear rail to protect the rod bearing and seal. To match this exact configuration for replacement, verify five points: 50 mm bore, 1280 mm stroke, PT port thread, the built-in magnet (-S suffix), and basic mounting (no bracket).
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 SC50X1280S FAQ
At 0.7 MPa operating pressure, the 50 mm bore SC cylinder produces a push force of 1374 N. The pull force on the retract stroke is 825 N at 0.5 MPa, reduced by the 20 mm rod area.
No. The AirTAC SC series is a tie-rod cylinder that is physically shorter than an ISO 15552 profile cylinder, so mounting dimensions and body length A (150 mm) are not interchangeable. It is a direct replacement only for another AirTAC SC50 tie-rod cylinder matching the bore, stroke, PT port, and -S magnet option.
