About the Airtac SC50 Standard Cylinder SC50X575S
The AirTAC SC50X575S is a double-acting single-rod pneumatic cylinder with a 50 mm bore and a non-standard 575 mm stroke, delivering 982 N of push force at 0.5 MPa. This model includes a built-in magnet (-S suffix), allowing CMSG/DMSG/EMSG reed or solid-state sensors to clamp directly onto the tie-rod barrel for reliable end-of-stroke detection without external brackets.
Built on a compact tie-rod body (A=150 mm), the SC50X575S uses a 20 mm diameter piston rod with an M16x1.5 male thread and PT1/4 ports. The adjustable air cushion (21 mm length) decelerates the piston near stroke end to reduce impact. With a total extended length of approximately 725 mm, this cylinder suits applications needing a long linear stroke in a cost-effective, non-ISO 15552 form factor.

Where the Airtac SC50 Standard Cylinder SC50X575S Is Used
Long-Reach Part Transfer
The 575 mm stroke moves components between distant conveyor lanes or workstations. The built-in magnet provides sensor feedback to confirm full extension and retraction in automated transfer lines.
Automated Sorting Gates
Actuates tall diverter gates or flippers on packaging and sorting lines. The adjustable cushion softens the stop at each end, protecting the gate mechanism from repeated impact at speed.
Pallet Dispenser Push
Pushes a stack of pallets or trays forward in a dispenser magazine. The 982 N force at 0.5 MPa is sufficient to slide a tall stack, and the magnet confirms the pusher has fully retracted before the next cycle.
Is the Airtac SC50 Standard Cylinder SC50X575S the Right Cylinder?
Choose the SC50X575S when your application needs roughly 980 N of push force at standard shop air. If you require more force, step up to the 63 mm bore (SC63 series, 1559 N at 0.5 MPa); for a lighter, more compact solution, the 40 mm bore (SC40 series, 628 N at 0.5 MPa) may suffice. This 575 mm stroke exceeds the standard maximum of 1200 mm for the 50 mm bore, so it is a made-to-order non-standard length.
For strokes of this length, side loading on the 20 mm rod is a critical design factor. Always guide the load externally with a linear rail or rod guide, or consider switching to a guided cylinder if the load is not perfectly axial. When replacing an existing cylinder, match five points: 50 mm bore, 575 mm stroke, PT1/4 port thread, the built-in magnet (-S), and the basic (no bracket) mounting style.
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 SC50X575S FAQ
At 0.5 MPa, the push force is 982 N and the pull force (rod side) is 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.
No. The SC50X575S is a double-acting cylinder and will not hold position if air pressure is lost or the valve is centered—the piston can drift or drop. For load holding, you must add an external rod lock, a pilot-operated check valve, or a mechanical brake.
