About the Airtac SC50 Standard Cylinder SC50X220SCB
The AirTAC SC50X220SCB is a 50 mm bore, 220 mm stroke double-acting tie-rod cylinder delivering a push force of 982 N at 0.5 MPa and up to 1767 N at 0.9 MPa operating pressure. Its 20 mm diameter piston rod and 21 mm adjustable air cushion provide reliable deceleration for mid-range automation tasks.
This model features a built-in magnet for mounting CMSG/DMSG/EMSG sensors directly on the barrel and a rear double clevis (CB) mount for pivoting applications. The F-SC50CB clevis bracket allows the cylinder to swing freely, making it ideal for articulated linkages where the actuator must follow an arc.

Where the Airtac SC50 Standard Cylinder SC50X220SCB Is Used
Agricultural Implement Control
Operates chute deflectors or hopper gates on seeding and harvesting equipment, where the rear clevis mount accommodates the structural flex of field machinery.
Part Diverter Gate
Swings a diverter arm on a conveyor line to sort packages by weight or barcode. The double clevis provides stable, repeatable pivoting motion under continuous cycling.
Clamp & Weld Fixture
Actuates a pivoting clamp arm in a robotic welding cell. The built-in magnet allows sensors to confirm clamp closure before the weld cycle begins, ensuring process safety.
Is the Airtac SC50 Standard Cylinder SC50X220SCB the Right Cylinder?
For higher force, step up to the 63 mm bore which provides 1559 N at 0.5 MPa; for a lighter, more compact solution, the 40 mm bore delivers 628 N. At 220 mm stroke, the SC50 rod is well-supported, but always avoid direct side loads on the rod end. For replacement, match these five points: 50 mm bore, 220 mm stroke, PT port thread, CB rear double clevis mounting, and the -S magnet 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 SC50X220SCB 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 SC50X220SCB is a double-acting cylinder that requires continuous air pressure to maintain position. If pressure is exhausted or the directional valve centers, the piston will drift. Use an external rod lock or pilot-operated check valve for static load holding.
