About the Airtac SC50 Standard Cylinder SC50X56
The SC50X56 is a compact-stroke pneumatic cylinder from the AirTAC SC tie-rod family, delivering a push force of 982 N at 0.5 MPa and up to 1767 N at the 0.9 MPa maximum operating pressure. Its 20 mm diameter piston rod and 21 mm adjustable air cushion provide reliable deceleration in a body length of just 150 mm, making it a space-efficient choice for short linear moves.
With a total extended length of approximately 206 mm, this 50 mm bore double-acting actuator is well-suited for clamping, ejecting, and sorting tasks where a short, controlled stroke is required. The PT1/4 port and M16x1.5 rod thread ensure straightforward pneumatic connections and tooling attachment.

Where the Airtac SC50 Standard Cylinder SC50X56 Is Used
Short-Stroke Clamping
The 56 mm stroke and 982 N force at 0.5 MPa are ideal for pneumatic clamping fixtures in woodworking or metal fabrication, providing a firm hold without excessive cylinder length.
Part Ejection & Sorting
Delivers a quick, repeatable push to divert or eject parts from a conveyor line. The adjustable cushion softens the end-of-stroke impact, protecting the cylinder and the product.
Automated Assembly Press
Used in benchtop assembly stations for pressing bushings, pins, or connectors. The compact body length fits easily into tight machine envelopes.
Is the Airtac SC50 Standard Cylinder SC50X56 the Right Cylinder?
For applications needing more force, stepping up to the 63 mm bore SC63 series provides 1559 N of push force at the same 0.5 MPa pressure. If a shorter stroke or lower force is acceptable, the 40 mm bore SC40 series offers 628 N. This model uses the standard PT thread and TPU seals, with no magnet or mounting accessories.
When replacing this cylinder, match five key points to ensure direct compatibility: the 50 mm bore, 56 mm stroke, PT1/4 port thread, the basic (no bracket) mounting configuration, and the absence of a built-in magnet. The SC is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders.
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 SC50X56 FAQ
At the standard 0.5 MPa operating pressure, 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 with a shorter overall body length than an ISO 15552 profile cylinder. It is not dimensionally interchangeable. It can only replace another AirTAC SC tie-rod cylinder with the same bore, stroke, port thread, and mounting configuration.
