About the Airtac SC50 Standard Cylinder SC50X275SLB
The SC50X275SLB is a double-acting pneumatic cylinder delivering 982 N of push force at 0.5 MPa and up to 1767 N at the maximum operating pressure of 0.9 MPa. With a 50 mm bore and a 275 mm stroke, this model is well-suited for medium-force material handling and clamping tasks. The 20 mm diameter piston rod and 21 mm adjustable air cushion at each end ensure smooth deceleration and reliable cycle life.
This specific configuration includes a built-in magnet (-S suffix) for mounting CMSG, DMSG, or EMSG reed and solid-state sensors directly on the tie-rod barrel. The LB foot mounting (F-SC50LB) provides a stable axial surface mount, and the TPU seals with PT ports maintain a standard operating range of -20 to +70 °C. The body length A is 150 mm, making the total extended length approximately 425 mm.

Where the Airtac SC50 Standard Cylinder SC50X275SLB Is Used
Conveyor Diverter
Actuates a medium-duty diverter gate on a packaging line, using the 275 mm stroke to reliably push products onto a secondary conveyor.
Clamping & Fixturing
Provides consistent 982 N clamping force at 0.5 MPa for a CNC welding fixture, with sensor confirmation of the clamped position via the built-in magnet.
Lift Assist Mechanism
Powers a lift table for small pallets, where the LB foot mount offers a rigid, stationary base and the 275 mm stroke provides the necessary vertical travel.
Is the Airtac SC50 Standard Cylinder SC50X275SLB the Right Cylinder?
For applications needing more force, consider stepping up to the 63 mm bore SC63 series, which provides 1559 N of push at 0.5 MPa. If a lighter, more compact solution is acceptable, the 40 mm bore SC40 series offers 628 N at the same pressure. This 275 mm stroke is within the 1200 mm maximum standard stroke for the 50 mm bore.
To ensure a correct replacement, match five key points: the 50 mm bore, 275 mm stroke, PT port thread, the LB foot mounting accessory, and the -S magnet option for sensor compatibility. For strokes over 300 mm on this rod size, be aware of potential rod deflection under side loads; an external guide or a guided cylinder is recommended to protect the rod bearing and seals.
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 SC50X275SLB FAQ
At 0.7 MPa operating pressure, the theoretical push force on the piston is 1374 N. The pull force on the rod side is 825 N at the same pressure, due to the area reduction from the 20 mm rod.
Yes. The -S suffix in the model code SC50X275SLB indicates a built-in magnet on the piston. This allows you to clamp AirTAC CMSG, DMSG, or EMSG sensors directly onto the cylinder's tie-rod barrel to detect piston position without any additional brackets.
