About the Airtac SC50 Standard Cylinder SC50X1000SLB
The SC50X1000SLB is a double-acting pneumatic cylinder delivering 982 N of push force at 0.5 MPa (1374 N at 0.7 MPa), making it a capable mid-bore actuator for linear transfer and pressing tasks. With a 1000 mm stroke and a 20 mm diameter piston rod, it provides extended reach while the 21 mm adjustable air cushion at each end decelerates the piston smoothly to reduce end-of-stroke impact.
This configuration includes a built-in magnet (suffix S) for mounting CMSG/DMSG/EMSG sensors directly on the tie-rod barrel, enabling reliable end-of-stroke or mid-position sensing. The LB suffix specifies axial foot mounts (F-SC50LB) for secure surface mounting, and the standard TPU seals and PT ports keep it suitable for general industrial air service from -20 to +70 °C.

Where the Airtac SC50 Standard Cylinder SC50X1000SLB Is Used
Long-Reach Part Transfer
The 1000 mm stroke moves components between distant conveyor lanes or workstations. The built-in magnet allows sensor confirmation of full extension and retraction at each end of the long travel.
Automated Gluing or Dispensing
Delivers consistent 982 N force at 0.5 MPa to press a dispensing head along a linear path. The LB foot mounts provide a stable, rigid base for the extended stroke length.
Pallet or Box Indexing
Pushes heavy boxes or pallets across roller beds. The adjustable cushion protects the cylinder and load from shock at the end of the 1000 mm stroke, extending service life in high-cycle logistics operations.
Is the Airtac SC50 Standard Cylinder SC50X1000SLB the Right Cylinder?
Select the SC50 bore when your application needs between 825 N (pull) and 982 N (push) at standard 0.5 MPa shop air. If the load is lighter, stepping down to a 40 mm bore (628 N push) saves air consumption; for heavier loads, the 63 mm bore provides 1559 N push. At 1000 mm stroke, the rod is fully supported by the piston and front bushing, but any significant side load will cause rod deflection—consider an external linear guide or a guided cylinder if the load is not purely axial.
To replace an existing cylinder, match five points exactly: 50 mm bore, 1000 mm stroke, PT port thread, LB foot mounting (F-SC50LB), and the -S magnet for sensor compatibility. The SC is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders.
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 SC50X1000SLB FAQ
At 0.5 MPa, the push force is 982 N and the pull force is 825 N. At the maximum operating pressure of 0.9 MPa, push force reaches 1767 N. The theoretical maximum at 1.0 MPa is 200 kgf.
No. The SC50 is a double-acting cylinder and will not hold position when air pressure is exhausted or the directional valve is centered. The piston will drift or the load will drop. For load holding, you must add a pilot-operated check valve, a rod lock, or an external mechanical brake.
