About the Airtac SC50 Standard Cylinder SC50X1180S
The AirTAC SC50X1180S is a double-acting single-rod pneumatic cylinder with a 50 mm bore and a long 1180 mm stroke, producing 982 N of push force at 0.5 MPa (1767 N at 0.9 MPa). Its 20 mm diameter rod and 21 mm adjustable air cushion help manage end-of-stroke deceleration even on extended travel cycles.
This model includes the -S suffix, meaning a built-in magnet is fitted directly to the piston. This allows standard CMSG, DMSG, or EMSG reed and solid-state sensors to clamp onto the tie-rod barrel for non-contact position sensing without extra brackets. The body length A is 150 mm, giving a total extended length of approximately 1330 mm.

Where the Airtac SC50 Standard Cylinder SC50X1180S Is Used
Long-Reach Part Transfer
The 1180 mm stroke moves components across wide conveyor gaps or between distant workstations, with the built-in magnet enabling end-of-stroke sensor confirmation.
Automated Gluing & Dispensing
Delivers consistent 982 N push force at 0.5 MPa to depress a dispense head along a long linear bead, with cushioning to prevent fluid hammer at stroke ends.
Vertical Gate Actuation
Raises and lowers a tall hopper gate or chute door over a 1180 mm travel, using the magnet for open/closed position feedback to the control system.
Is the Airtac SC50 Standard Cylinder SC50X1180S the Right Cylinder?
For applications needing more force, stepping up to the 63 mm bore (SC63 series) provides 1559 N push at 0.5 MPa. If a shorter, more rigid setup is acceptable, the 40 mm bore SC40 series offers 628 N at 0.5 MPa. At this 1180 mm stroke, the unsupported rod is vulnerable to bending under side loads; always use an external linear guide or rod-alignment coupler to protect the rod bearing and seals.
To match this cylinder for a replacement, verify five points: 50 mm bore, 1180 mm stroke, PT1/4 port thread, the built-in magnet (-S), and the basic (no bracket) mounting configuration. The SC is a tie-rod cylinder and is dimensionally shorter than ISO 15552 profiles, so only another AirTAC SC50 of the same stroke is a direct drop-in.
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 SC50X1180S FAQ
At 0.5 MPa operating pressure, the cylinder provides 982 N pushing force and 825 N pulling force. At the maximum operating pressure of 0.9 MPa, the push force reaches 1767 N.
Yes. The magnet works with AirTAC CMSG (reed) and DMSG/EMSG (solid-state) sensors, which clamp directly onto the cylinder's tie rods. This provides non-contact position sensing at any point along the 1180 mm stroke.
