About the Airtac SC50 Standard Cylinder SC50X670S
The AirTAC SC50X670S is a double-acting tie-rod cylinder with a 50 mm bore and a 670 mm stroke, factory-equipped with a built-in magnet (-S suffix) so CMSG/DMSG/EMSG reed or solid-state sensors can clamp directly onto the barrel for contactless position sensing. At 0.5 MPa it provides 982 N push and 825 N pull force, with a 20 mm piston rod and M16x1.5 rod thread for robust linear actuation.
This cylinder uses PT1/4 ports and an adjustable air cushion (21 mm cushion length) to decelerate the piston smoothly at stroke end. The body length A is 150 mm, giving a total extended length of approximately 820 mm. Operating pressure ranges from 0.15 to 1.0 MPa, with a proof pressure of 1.5 MPa, and the standard TPU/NBR seals suit temperatures from -20 to +70 °C.

Where the Airtac SC50 Standard Cylinder SC50X670S Is Used
Material Handling Gates
The 670 mm stroke and 982 N push force at 0.5 MPa suit diverters and lane gates on conveyors, with the built-in magnet enabling end-of-stroke confirmation via barrel-mounted sensors.
Automated Press Feeders
Delivers consistent linear feed motion for sheet or strip material into stamping presses, where the adjustable cushion protects tooling from impact at the end of each 670 mm advance.
Palletiser Pusher Arms
Provides the long reach needed to push boxes or layers onto a pallet. The magnetic piston allows programmable logic controllers to verify arm position at both ends of travel.
Is the Airtac SC50 Standard Cylinder SC50X670S the Right Cylinder?
For applications needing slightly less force, the 40 mm bore SC40 series provides 628 N push at 0.5 MPa in a more compact body. If higher force is required, stepping up to the 63 mm bore delivers 1559 N at the same pressure. The 670 mm stroke is within the 1200 mm maximum standard stroke for bore 50, so no non-standard surcharge applies.
At this stroke length, ensure the 20 mm rod is adequately supported if side loads are present—long unsupported rods are susceptible to bending. Use an external linear guide or a guided cylinder for off-axis loads. When replacing an existing unit, match five points: 50 mm bore, 670 mm stroke, PT port thread, basic mounting (no integral bracket), and the -S magnet for sensor compatibility.
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 SC50X670S FAQ
At 0.7 MPa (7 bar) the SC50X670S produces 1374 N of push force. The theoretical maximum at 1.0 MPa is 200 kgf (1961 N), but the recommended operating range is 0.15–1.0 MPa.
Yes. The -S suffix in SC50X670S indicates a built-in magnet inside the piston. This allows AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors to be clamped onto the barrel tie-rods for contactless position detection without any additional brackets.
