About the Airtac SC50 Standard Cylinder SC50X680S
The SC50X680S is a double-acting pneumatic cylinder delivering 982 N of push force at 0.5 MPa (1767 N at 0.9 MPa). Its 20 mm diameter piston rod and 21 mm adjustable air cushion provide smooth deceleration over a 680 mm stroke.
This model includes a built-in magnet (-S suffix), allowing CMSG, DMSG, or EMSG reed and solid-state sensors to clamp directly onto the tie-rod barrel for non-contact position sensing. The body length A is 150 mm, resulting in a total extended length of approximately 830 mm.

Where the Airtac SC50 Standard Cylinder SC50X680S Is Used
Material Handling Gates
Actuates diverter gates on conveyor lines, with the 680 mm stroke providing ample reach and the built-in magnet enabling end-of-stroke sensor feedback.
Automated Clamping Fixtures
Delivers 982 N of consistent clamping force for medium-duty CNC jigs, with sensors confirming part presence before machining cycles start.
Palletizing Pushers
Pushes boxes onto pallets with a 680 mm stroke, using the adjustable cushion to gently stop the load without jarring the packaging.
Is the Airtac SC50 Standard Cylinder SC50X680S the Right Cylinder?
For applications needing more force, stepping up to the 63 mm bore SC63 series provides 1559 N at 0.5 MPa. If a shorter, more compact cylinder is sufficient, the 40 mm bore delivers 628 N. At a 680 mm stroke, ensure side loads are minimal or use an external guide rail, as the unsupported 20 mm rod can experience bending under off-axis forces.
When replacing this cylinder, match five key points: 50 mm bore, 680 mm stroke, PT1/4 port thread, the built-in magnet for sensor compatibility, and the basic (no bracket) mounting configuration.
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 SC50X680S 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, the push force reaches 1767 N.
Yes. The -S suffix in the model code indicates a built-in magnet, making it compatible with AirTAC CMSG, DMSG, and EMSG series sensors that clamp onto the barrel for position detection.
