About the Airtac SC50 Standard Cylinder SC50X1050S
The AirTAC SC50X1050S is a double-acting single-rod tie-rod cylinder with a 50 mm bore and a 1050 mm stroke, delivering a push force of 982 N at 0.5 MPa and up to 1767 N at the maximum operating pressure of 0.9 MPa. Its 20 mm diameter piston rod and 21 mm adjustable air cushion provide reliable deceleration for mid-range linear tasks, while the built-in magnet allows direct mounting of CMSG/DMSG/EMSG sensors for contactless position feedback.
With a body length A of 150 mm, this cylinder extends to a total length of approximately 1200 mm. The SC50X1050S is a genuine AirTAC pneumatic component, factory-equipped with PT1/4 ports and an M16x1.5 rod thread, making it a straightforward choice for automation builders who need sensor-ready stroke confirmation on a long-travel axis.

Where the Airtac SC50 Standard Cylinder SC50X1050S Is Used
Long-Stroke Part Transfer
Moves components between distant conveyor lanes or assembly stations with sensor-verified end-of-stroke detection, ensuring the transfer arm has fully retracted before the next cycle.
Automated Gluing & Dispensing
Drives a dispensing head across a 1050 mm work envelope. The built-in magnet triggers a CMSG sensor to confirm position, synchronising the bead start/stop with cylinder motion.
Vertical Lift Gate Actuation
Operates a tall lift gate or hopper door in material handling lines. The adjustable air cushion softens the stop at both ends, reducing wear on the gate linkage over millions of cycles.
Is the Airtac SC50 Standard Cylinder SC50X1050S the Right Cylinder?
Choose the SC50X1050S when your application needs approximately 982 N of push force at standard plant pressure. If you require higher force, stepping up to the 63 mm bore provides 1559 N at 0.5 MPa; for a lighter, more compact solution, the 40 mm bore offers 628 N. At 1050 mm of stroke, the piston rod is fully supported within the cylinder but is susceptible to bending under side loads—always use an external linear guide or rod-alignment coupler to protect the rod bearing and seals.
For replacement, match five key points: 50 mm bore, 1050 mm stroke, PT1/4 port thread, the built-in magnet (-S suffix), and your existing mounting accessory. This model ships without a mount (basic configuration), so transfer your current FA, FB, CA, CB, LB, or TC bracket directly to the new cylinder body.
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 SC50X1050S FAQ
At 0.5 MPa (5 bar) the cylinder pushes with 982 N and pulls with 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.
Long, unsupported strokes are vulnerable to side loads and buckling. Mount the load on an external linear guide rail and connect the rod via a floating joint or alignment coupler. Never use the rod itself as the sole guide, and ensure the load is centred on the rod axis.
