About the Airtac SC50 Standard Cylinder SC50X225CB
The AirTAC SC50X225CB is a 50 mm bore double-acting pneumatic cylinder with a 225 mm stroke, delivering a push force of 982 N at 0.5 MPa (up to 1767 N at 0.9 MPa). Its 20 mm diameter piston rod and 21 mm adjustable air cushion provide reliable deceleration for mid-range automation tasks.
This model is configured with a rear double clevis (CB) mount, allowing the cylinder body to pivot during operation, which is ideal for articulated linkages. The standard PT1/4 port and TPU seals suit general industrial environments with a -20 to +70 °C temperature range.

Where the Airtac SC50 Standard Cylinder SC50X225CB Is Used
Clamping & Fixturing
The 982 N force at 0.5 MPa makes this cylinder suitable for pneumatic clamping systems on CNC jigs and welding fixtures, where the rear clevis mount accommodates the fixture's swing-arm motion.
Part Diverter Gates
With its pivoting CB mount, the SC50X225CB can actuate diverter gates on conveyor lines, reliably pushing packages or components onto different lanes with a 225 mm stroke.
Agricultural Machinery
Used in automated farm equipment like sorting gates or chute controls, the TPU seals and tie-rod design handle dusty conditions, while the clevis mount allows for the necessary angular movement.
Is the Airtac SC50 Standard Cylinder SC50X225CB the Right Cylinder?
Choose the SC50 when your application needs around 982 N of push force at standard shop air; if you require more force, step up to the SC63 which provides 1559 N at the same 0.5 MPa pressure. For lighter, more compact machines, the SC40 offers 628 N.
This 225 mm stroke is within the standard range for the 50 mm bore, but always ensure the rod is not subjected to direct side loads. For precise replacement, match five points: 50 mm bore, 225 mm stroke, PT thread, CB rear double clevis mount (F-SC50CB), and the non-magnetic piston configuration.
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 SC50X225CB 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, the push force increases to 1767 N. The theoretical maximum force at 1.0 MPa is 200 kgf.
No. The AirTAC SC series is a tie-rod cylinder and is physically shorter than an ISO 15552 profile cylinder, so it is not dimensionally interchangeable. It is a direct replacement only for another AirTAC SC50 tie-rod cylinder with the same bore, stroke, PT port, and CB rear double clevis mount.
