About the Airtac SC50 Standard Cylinder SC50X900
The AirTAC SC50X900 is a double-acting tie-rod cylinder delivering 982 N of push force at 0.5 MPa and up to 1767 N at the maximum operating pressure of 0.9 MPa. With a 50 mm bore and a 20 mm piston rod, this 900 mm stroke model provides a compact yet powerful linear drive solution for medium-duty automation tasks.
This cylinder features a body length (A) of 150 mm and a 21 mm adjustable air cushion at each end to decelerate the piston smoothly, reducing impact and noise. The rod thread is M16x1.5 and the standard port size is PT1/4. Operating on filtered air from 0.15 to 1.0 MPa, the SC50X900 is built for reliable, high-cycle performance in industrial environments.

Where the Airtac SC50 Standard Cylinder SC50X900 Is Used
Material Transfer
The 900 mm stroke is ideal for pushing or lifting boxes and components between conveyor lines in packaging and logistics hubs, where the 982 N force at 0.5 MPa handles moderate payloads.
Machine Tool Actuation
Provides the long, consistent stroke needed for automatic door operation or tool-changing mechanisms on CNC machines, utilizing the smooth adjustable cushioning for precise end-of-stroke deceleration.
Automated Sorting Gates
Deploys in high-speed sorting systems to divert products on gravity or powered rollers. The double-acting control ensures positive retraction and extension for reliable, repetitive cycling.
Is the Airtac SC50 Standard Cylinder SC50X900 the Right Cylinder?
For applications requiring more force, stepping up to the 63 mm bore SC63 series provides 1559 N at 0.5 MPa. If a lower force and a lighter, more compact cylinder is preferred, the 40 mm bore SC40 series offers 628 N. At a 900 mm stroke, ensure the load is guided externally to prevent side-loading the rod bearing, as long, unsupported strokes are susceptible to bending under lateral forces.
When replacing an existing cylinder, match five critical points: 50 mm bore, 900 mm stroke, PT1/4 port thread, basic (no) mounting accessories, and the absence of a built-in magnet. This model uses standard TPU seals with a temperature range of -20 to +70 °C.
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 SC50X900 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. For any stroke of 300 mm or more, and especially at 900 mm, the 20 mm piston rod is vulnerable to bending under side loads. The load must be supported on external linear guides or rails to prevent damage to the rod bearing and seals, ensuring long service life.
