About the Airtac SC50 Standard Cylinder SC50X75
The AirTAC SC50X75 is a 50 mm bore, 75 mm stroke double-acting pneumatic cylinder from the SC tie-rod series. At 0.5 MPa it delivers 982 N push and 825 N pull, making it a capable mid-range actuator for short linear moves.
This model uses a 20 mm diameter piston rod with M16x1.5 male threads and PT1/4 ports. The adjustable air cushion (21 mm length) decelerates the piston smoothly at each end of the 75 mm stroke, reducing end-cap impact. Body length A is 150 mm, giving a compact extended length of approximately 225 mm.

Where the Airtac SC50 Standard Cylinder SC50X75 Is Used
Part Stops & Diverters
Provides the short, firm push needed to stop or divert light packages on a conveyor line, operating reliably at standard plant air pressure.
Clamping & Holding
Delivers 982 N of clamping force for workholding jigs in CNC machining or assembly fixtures, with a clean 75 mm stroke for part clearance.
Gate & Flap Actuation
Opens and closes small hopper gates or diverter flaps in material handling, where the 20 mm rod and tie-rod construction handle repetitive cycling.
Is the Airtac SC50 Standard Cylinder SC50X75 the Right Cylinder?
Choose the SC50X75 when your application needs roughly 980 N of push force at standard shop air. If you require more force, the 63 mm bore SC63 series provides 1559 N at 0.5 MPa; for a lighter, more compact solution, the 40 mm bore delivers 628 N. Always match replacement cylinders on all five key points: bore (50 mm), stroke (75 mm), port thread (PT1/4), mounting accessory, and magnet option.
For this 75 mm stroke, side loading is rarely a concern, but if the rod sees any radial force, add an external guide rail or switch to a guided cylinder to protect the rod bearing and piston seals from uneven 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 SC50X75 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, push force reaches 1767 N. The theoretical maximum at 1.0 MPa is 200 kgf.
Yes, if the original is an AirTAC SC50X75 with PT ports and no magnet or special mounting. Confirm the bore (50 mm), stroke (75 mm), port thread (PT1/4), mounting style, and magnet option all match. This is a tie-rod cylinder and will not interchange with ISO 15552 profile cylinders.
