About the Airtac SC50 Standard Cylinder SC50X40SN
The AirTAC SC50X40SN is a double-acting tie-rod cylinder with a 50 mm bore and 40 mm stroke, delivering a push force of 982 N at 0.5 MPa (up to 1767 N at 0.9 MPa). Its compact 150 mm body length A results in a total extended length of approximately 190 mm, making it suitable for tight installations.
This model includes a built-in magnet (-S suffix), allowing CMSG, DMSG, or EMSG sensors to clamp directly onto the barrel for contactless position sensing. The -N suffix specifies NBR (nitrile) seals, and the standard PT (Rc) port thread is retained. The 20 mm diameter rod with M16x1.5 thread provides robust push/pull capability for short-stroke clamping and ejecting tasks.

Where the Airtac SC50 Standard Cylinder SC50X40SN Is Used
Sensed Short-Stroke Clamping
The 40 mm stroke with integrated magnetic piston enables precise end-of-stroke sensing for automated clamping fixtures, confirming part presence before machining cycles begin.
NBR-Sealed Light Assembly
NBR seals offer reliable performance with standard lubricated air in clean assembly environments, making this cylinder ideal for pick-and-place units requiring position feedback.
Product Stops & Diverters
Delivering 982 N at 0.5 MPa, the SC50X40SN provides ample force for stopping cartons or diverting small packages on conveyor lines, with sensors confirming gate position.
Is the Airtac SC50 Standard Cylinder SC50X40SN the Right Cylinder?
Choose the SC50X40SN when you need a compact 50 mm bore cylinder with integrated position sensing and NBR seals. If higher force is required, stepping up to the 63 mm bore provides 1559 N at 0.5 MPa. For lower force applications, the 40 mm bore delivers 628 N.
For a direct replacement, match these five attributes: 50 mm bore, 40 mm stroke, PT port thread, built-in magnet (-S), and NBR seal material. The SC series is a tie-rod design 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 SC50X40SN FAQ
At the standard operating pressure of 0.5 MPa, the cylinder produces 982 N pushing force and 825 N pulling force. At the maximum operating pressure of 0.9 MPa, the push force increases to 1767 N.
Yes. The -S suffix in the model code indicates a built-in magnet on the piston. This allows you to directly clamp AirTAC CMSG, DMSG, or EMSG reed and solid-state sensors onto the barrel for contactless position detection.
