About the Airtac SC50 Standard Cylinder SC50X70S
The SC50X70S is a double-acting tie-rod cylinder with a 50 mm bore and 70 mm stroke, pre-fitted with a built-in magnet for direct mounting of CMSG/DMSG/EMSG reed or solid-state sensors. It generates a push force of 982 N at 0.5 MPa and 1767 N at the maximum operating pressure of 0.9 MPa, making it a reliable mid-range actuator for automated positioning tasks.
This model uses a 20 mm diameter piston rod with an M16x1.5 male thread and PT1/4 ports. The adjustable air cushion at each end (21 mm length) decelerates the piston smoothly, reducing end-of-stroke impact. The body length A is 150 mm, giving a total extended length of approximately 220 mm.

Where the Airtac SC50 Standard Cylinder SC50X70S Is Used
Conveyor Diverter Gate
Actuates a light to medium diverter gate on a packaging line. The 70 mm stroke provides a crisp push, while the magnetic piston enables sensor feedback to confirm gate position before the next cycle.
Small Press Jig Clamp
Drives a clamping arm in a woodworking or light metalworking jig. The 982 N force at 0.5 MPa holds workpieces securely during drilling or routing, and the adjustable cushion prevents vibration marks on the part.
Laboratory Sample Ejector
Pushes test tube racks or sample trays out of an analysis machine. The magnetic piston sensor verifies full extension, ensuring the rack is fully presented for the robotic pipetting arm.
Is the Airtac SC50 Standard Cylinder SC50X70S the Right Cylinder?
For applications needing less force, the 40 mm bore SC series provides 628 N push at 0.5 MPa; for higher force, step up to the 63 mm bore which delivers 1559 N at the same pressure. The built-in magnet (suffix -S) allows tool-free sensor clamping along the barrel for electrical end-of-stroke confirmation.
When replacing this cylinder, match five points: 50 mm bore, 70 mm stroke, PT1/4 port thread, the basic footless mounting configuration, and the integrated magnet feature. The SC 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 SC50X70S FAQ
At the standard 0.5 MPa operating pressure, 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. The theoretical maximum force at 1.0 MPa is 200 kgf.
Yes. The -S suffix indicates a built-in magnet in the piston. You can clamp AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the tie-rod barrel to detect piston position without any additional brackets.
