About the Airtac SC50 Standard Cylinder SC50X1200SN
The AirTAC SC50X1200N 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 a full 1200 mm stroke, it is built for long linear movements in automation, pressing, and material transfer. The 20 mm diameter piston rod provides robust column strength, and the adjustable pneumatic cushion (21 mm length) decelerates the piston smoothly at each end to reduce impact wear.
This model is fitted with NBR (nitrile) seals, suitable for standard operating temperatures from -20 to +70 °C. The PT1/4 port thread ensures straightforward pneumatic plumbing. As a genuine AirTAC SC-series cylinder, it offers a compact tie-rod design that is shorter than an equivalent ISO 15552 profile cylinder, making it ideal where space is limited.

Where the Airtac SC50 Standard Cylinder SC50X1200SN Is Used
Long-Stroke Material Transfer
Moves components or pallets across a 1200 mm span on linear transfer lines, using its full push force of 1767 N at 0.9 MPa for smooth, controlled actuation.
Automated Pressing & Assembly
Applies consistent insertion or pressing force over a long working distance in assembly fixtures, with the adjustable cushion protecting tooling at end-of-stroke.
Packaging & Palletizing Systems
Drives sweep arms or pushers in large packaging machines, leveraging the 1200 mm stroke to handle wide conveyor beds and pallet layers efficiently.
Is the Airtac SC50 Standard Cylinder SC50X1200SN the Right Cylinder?
For applications needing slightly less force, consider stepping down to the 40 mm bore (628 N at 0.5 MPa). If higher force is required, the 63 mm bore provides 1559 N at the same pressure. At this 1200 mm stroke length, side loads must be carefully managed—an unsupported 20 mm rod at full extension is vulnerable to bending. Use an external linear guide or a guided cylinder configuration to protect the rod bearings and ensure reliable operation.
When replacing an existing cylinder, match five key points: 50 mm bore, 1200 mm stroke, PT1/4 port thread, basic mounting (no accessory bracket), and the absence of a built-in magnet. This NBR-sealed variant is a direct replacement for another AirTAC SC50X1200N or a compatible tie-rod cylinder with identical specifications.
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 SC50X1200SN FAQ
At 0.5 MPa operating pressure, the cylinder produces 982 N extending (push) and 825 N retracting (pull). 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 body length than an ISO 15552 cylinder, so it is not dimensionally interchangeable. It directly replaces another AirTAC SC50 cylinder with the same bore, stroke, NBR seals, and PT ports.
