About the Airtac SC50 Standard Cylinder SC50X750
The SC50X750 is a double-acting tie-rod cylinder delivering 982 N of push force and 825 N of pull force when operated at 0.5 MPa. With a 50 mm bore and a 750 mm stroke, it is well-suited for medium-duty linear transfer and clamping tasks where a longer reach is required. The piston rod diameter is 20 mm with an M16x1.5 male thread, and the body length A is 150 mm, giving a total extended length of approximately 900 mm.
This model features a 21 mm adjustable air cushion at both ends to decelerate the piston smoothly, reducing end-of-stroke impact. The standard PT1/4 port and TPU seals offer reliable performance in normal industrial environments from -20 to +70 °C. As a genuine AirTAC SC series cylinder, it provides a compact, shorter alternative to ISO 15552 profiles.

Where the Airtac SC50 Standard Cylinder SC50X750 Is Used
Long-Reach Part Transfer
Ideal for pushing or pulling components across a 750 mm span in packaging lines or assembly stations, using the 982 N force at 0.5 MPa to move moderate loads reliably.
Automated Clamping Fixtures
Provides consistent clamping force for woodworking or metal fabrication jigs, with the adjustable cushion protecting the fixture from shock at the end of the stroke.
Diverting Gates on Conveyors
Actuates diverter arms or gates in material handling systems, where the 750 mm stroke offers the necessary reach and the tie-rod design allows for straightforward maintenance.
Is the Airtac SC50 Standard Cylinder SC50X750 the Right Cylinder?
For applications requiring slightly less force, consider stepping down to the 40 mm bore (628 N at 0.5 MPa). If higher force is needed, the 63 mm bore provides 1559 N at the same pressure. At a 750 mm stroke, the 20 mm rod is extended significantly; ensure side loads are minimal or use an external guide system to prevent rod bending and premature bearing wear. When replacing an existing cylinder, match five points: 50 mm bore, 750 mm stroke, PT1/4 port thread, basic mounting (no bracket), and confirm the magnet requirement (this model has no built-in magnet).
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 SC50X750 FAQ
At 0.7 MPa operating pressure, the theoretical push force is 1374 N and the pull force is 1155 N (calculated from the 825 N pull force at 0.5 MPa). The maximum operating force at 0.9 MPa is 1767 N push.
For a 750 mm stroke with a 20 mm rod, the cylinder is susceptible to rod buckling and side-load damage. It is strongly recommended to use an external guide rail or rod alignment coupler if the load is not perfectly axial, to prevent bending and extend seal life.
