About the Airtac SC50 Standard Cylinder SC50X210
The AirTAC SC50X210 is a double-acting tie-rod cylinder delivering 982 N of push force at 0.5 MPa (1767 N at 0.9 MPa). With a 50 mm bore and 210 mm stroke, it suits medium-force clamping and pressing tasks. The 20 mm diameter piston rod and 21 mm adjustable air cushion at each end provide smooth deceleration.
This model uses the standard PT1/4 port thread and TPU seals for a -20 to +70 C operating range. The body length A is 150 mm, giving a compact footprint for machine builders. It is a genuine AirTAC SC series actuator, not an ISO 15552 profile cylinder, and is shorter than an equivalent ISO 15552 unit.

Where the Airtac SC50 Standard Cylinder SC50X210 Is Used
Part Stops & Gates
The 982 N push force at 0.5 MPa reliably stops or diverts medium-weight packages on conveyor lines, with the 210 mm stroke providing ample reach across the belt width.
Clamping Fixtures
Ideal for pneumatic clamping in woodworking or light metal fabrication jigs. The adjustable cushion reduces impact noise and vibration at the end of the 210 mm clamping stroke.
Press & Assembly Tools
Delivers up to 1767 N at 0.9 MPa for pressing bearings, bushings, or rivets in assembly stations. The tie-rod construction allows easy maintenance in high-cycle production environments.
Is the Airtac SC50 Standard Cylinder SC50X210 the Right Cylinder?
Choose the SC50X210 when your application needs around 982 N at 0.5 MPa. If you require more force, the SC63 bore steps up to 1559 N at the same pressure. For lighter, faster cycles, the SC40 offers 628 N. Always match bore, 210 mm stroke, PT1/4 ports, and basic mounting when replacing an existing SC50 cylinder.
At 210 mm stroke, side loads are a moderate concern. Ensure the load is guided externally and aligned axially with the rod to prevent bending stress on the 20 mm rod and premature bearing wear.
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 SC50X210 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 reaches 1767 N. The theoretical maximum at 1.0 MPa is 200 kgf.
No. The AirTAC SC series is a tie-rod cylinder that is physically shorter than an ISO 15552 profile cylinder of the same bore and stroke. It will only directly replace another AirTAC SC50 cylinder with matching bore, stroke, PT1/4 ports, and basic mounting.
