About the Airtac SC50 Standard Cylinder SC50X225N
The AirTAC SC50X225N is a double-acting single-rod pneumatic cylinder with a 50 mm bore and 225 mm stroke, delivering a push force of 982 N at 0.5 MPa and up to 1767 N at 0.9 MPa. Its 20 mm diameter piston rod and PT1/4 port provide a robust connection for medium-duty linear motion tasks, while the 21 mm adjustable air cushion at each end decelerates the piston smoothly to reduce end-of-stroke impact.
This model is fitted with NBR (nitrile) seals, making it a cost-effective choice for general industrial environments within the standard -20 to +70 °C temperature range. With a body length A of 150 mm, the total extended length is approximately 375 mm, offering a compact yet powerful solution for pushing, pressing, and clamping operations.

Where the Airtac SC50 Standard Cylinder SC50X225N Is Used
Part Rejection Gates
The 225 mm stroke and 982 N push force at 0.5 MPa reliably actuates diverter gates on conveyor lines, sorting packages or rejecting defective products with crisp, repeatable motion.
Clamping & Fixturing
Ideal for medium-force workholding jigs in CNC machining or assembly, the SC50X225N applies consistent clamping pressure to secure parts during drilling, welding, or bonding.
Box Flap Folding
Used in case erectors and packaging machinery, this cylinder extends to fold cardboard flaps with controlled speed, aided by the adjustable cushion to prevent crushing the carton.
Is the Airtac SC50 Standard Cylinder SC50X225N the Right Cylinder?
For applications needing more force, stepping up to the 63 mm bore SC63 series provides 1559 N at 0.5 MPa, while the 40 mm bore SC40 delivers 628 N if a smaller footprint is required. At a 225 mm stroke, side-loading should be avoided; if the rod must bear lateral forces, use an external linear guide or switch to a guided cylinder to prevent premature rod bearing wear.
When replacing an existing cylinder, match five key points: 50 mm bore, 225 mm stroke, PT1/4 port thread, NBR seal material, and the basic (no-mount) configuration. This SC series 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 SC50X225N FAQ
At 0.5 MPa the push force is 982 N and pull force is 825 N. At 0.7 MPa push reaches 1374 N, and at the maximum operating pressure of 0.9 MPa it delivers 1767 N. The theoretical maximum 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 profile cylinder, so mounting dimensions and overall length differ. It will only drop-in replace another AirTAC SC tie-rod cylinder with matching bore, stroke, port thread, and mounting.
