About the Airtac SC50 Standard Cylinder SC50X1100SLB
The AirTAC SC50X1100SLB is a double-acting single-rod pneumatic cylinder delivering 982 N of push force at 0.5 MPa (1767 N at 0.9 MPa). With an 1100 mm stroke and a 20 mm diameter piston rod, this model suits long linear movements in material handling and automation where consistent thrust is required.
This configuration includes a built-in magnet (-S suffix) for mounting CMSG/DMSG/EMSG sensors directly on the tie-rod barrel, enabling precise end-of-stroke or mid-stroke position sensing. The LB suffix specifies axial foot mounts (part F-SC50LB) for secure surface installation. The body length A is 150 mm, giving a total extended length of approximately 1250 mm.

Where the Airtac SC50 Standard Cylinder SC50X1100SLB Is Used
Long-Stroke Part Transfer
Moves components or pallets over an 1100 mm distance on linear transfer lines, with sensor feedback confirming each end position.
Automated Gluing or Dispensing
Provides the long, steady linear motion needed for applying adhesives or sealants across large workpieces in furniture or automotive assembly.
Vertical Lift Gate Actuation
Operates a tall lift gate or hopper door with 982 N of force, using the foot mount for stable attachment to the machine frame.
Is the Airtac SC50 Standard Cylinder SC50X1100SLB the Right Cylinder?
For applications requiring more force, consider stepping up to the 63 mm bore SC63 series, which provides 1559 N at 0.5 MPa. If a shorter, more compact solution is acceptable, the 40 mm bore SC40 series offers 628 N at 0.5 MPa. At this 1100 mm stroke, side loads and rod deflection are critical concerns. Always use an external linear guide or rod support to prevent bending of the 20 mm rod, as the SC series is not designed to absorb significant radial forces. To ensure a correct replacement, match five key specifications: 50 mm bore, 1100 mm stroke, PT port thread, LB foot mounting, and the -S magnet option for sensor compatibility.
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 SC50X1100SLB FAQ
At the standard 0.5 MPa operating pressure, 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 reaches 1767 N.
Match five key points: the 50 mm bore, the 1100 mm stroke, the PT (Rc) port thread, the LB foot mounting style, and the built-in magnet for sensors. Also verify the 20 mm rod diameter and M16x1.5 rod thread. This is a tie-rod cylinder and will not directly interchange with an ISO 15552 profile cylinder.
