About the Airtac SC50 Standard Cylinder SC50X220
The SC50X220 is a 50 mm bore, 220 mm stroke double-acting pneumatic cylinder from the AirTAC SC tie-rod family. At 0.5 MPa it generates 982 N extending force and 825 N retracting force, making it a capable mid-range actuator for pressing, clamping, and lifting tasks. The 20 mm diameter piston rod and 21 mm adjustable air cushion at each end provide smooth deceleration, while the PT1/4 ports ensure straightforward pneumatic connection.
This model uses the standard TPU/NBR seals rated for -20 to +70 °C and ships in a basic configuration without a magnet or mounting accessories, giving you a clean foundation to add the exact brackets your application needs. The body length A is 150 mm, resulting in a compact extended length of approximately 370 mm for easy integration into machine frames.

Where the Airtac SC50 Standard Cylinder SC50X220 Is Used
Part Transfer
The 220 mm stroke and 982 N push force at 0.5 MPa reliably shift components between conveyor stations or indexing tables in automated assembly lines.
Light Pressing & Staking
Delivers up to 1767 N at 0.9 MPa for pressing bearings, bushings, or performing light staking operations in a controlled pneumatic cycle.
Clamping Fixtures
Ideal for actuating clamps on welding or machining fixtures, holding workpieces securely with its 20 mm rod and adjustable cushion for quiet operation.
Is the Airtac SC50 Standard Cylinder SC50X220 the Right Cylinder?
Choose the SC50X220 when your load requires around 980 N of push force at standard shop air. If you need more force, the SC63 bore delivers 1559 N at the same 0.5 MPa; if space is tight, the SC40 provides 628 N. For this 220 mm stroke, side loads are manageable, but always align the rod with the load axis to prevent bending. When replacing an existing cylinder, match five points: 50 mm bore, 220 mm stroke, PT1/4 port thread, any mounting accessory (this is a basic body), and confirm whether the original had a magnet (-S suffix).
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 SC50X220 FAQ
At 0.5 MPa the extending force is 982 N and the retracting force is 825 N. At the maximum operating pressure of 0.9 MPa, the extending force reaches 1767 N. The theoretical maximum 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 dimensions are not interchangeable. It is a direct replacement only for another AirTAC SC50 tie-rod cylinder with the same bore, stroke, port thread, and mounting configuration.
