About the Airtac SC50 Standard Cylinder SC50X450SLB
The SC50X450SLB 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, 20 mm piston rod, and a 450 mm stroke, it is well-suited for medium-duty linear tasks requiring a moderate extension length.
This configuration includes a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors, and LB-type axial foot mounts (F-SC50LB) for secure surface installation. The tie-rod construction keeps the body length to 150 mm, giving a total extended length of 600 mm. It uses PT1/4 ports and standard TPU seals for a -20 to +70 °C operating range.

Where the Airtac SC50 Standard Cylinder SC50X450SLB Is Used
Material Stops & Gates
The 450 mm stroke and 1767 N max force reliably actuate heavy-duty stops and diverters on conveyor lines, with magnetic sensors confirming open/closed positions.
Clamping & Fixturing
Delivers consistent clamping force for medium-sized workpieces in CNC machining or welding fixtures, where the LB foot mount provides a stable, fixed platform.
Packaging Pushers
Ideal for pushing cartons or trays off a line in packaging machinery, using the 450 mm reach and sensor feedback to ensure complete product transfer.
Is the Airtac SC50 Standard Cylinder SC50X450SLB the Right Cylinder?
For applications needing more force, stepping up to the 63 mm bore provides 1559 N at 0.5 MPa. If a shorter, more compact cylinder is acceptable, the 40 mm bore offers 628 N. At a 450 mm stroke, ensure the rod is protected from side loads; an external guide or a guided cylinder is recommended to prevent rod bending and premature bearing wear.
When replacing an existing cylinder, match five points: 50 mm bore, 450 mm stroke, PT1/4 port thread, LB foot mounting (F-SC50LB), and the built-in magnet (-S) 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 SC50X450SLB FAQ
At 0.7 MPa (7 bar) operating pressure, the push force is 1374 N. The pull force at the same pressure is 825 N, accounting for the 20 mm piston rod area.
No. The SC50X450SLB is a double-acting cylinder and does not lock or hold position when air is exhausted. The piston will drift or drop. For load holding without live pressure, you must add a pilot-operated check valve or an external mechanical rod brake.
