About the Airtac SC50 Standard Cylinder SC50X1700S
The SC50X1700S is a double-acting pneumatic cylinder with a 50 mm bore and an extended 1700 mm stroke, built with a built-in magnet (S) for direct mounting of CMSG/DMSG/EMSG sensors. This long-stroke configuration delivers a push force of 982 N at 0.5 MPa and 1767 N at 0.9 MPa, making it suitable for long-reach linear actuation where position feedback is required.
This model uses a 20 mm diameter piston rod with an M16x1.5 thread and PT1/4 ports. The body length A is 150 mm, resulting in a total extended length of 1850 mm. As the 1700 mm stroke exceeds the 1200 mm maximum standard stroke for bore 50, this is a non-standard, made-to-order unit with a 21 mm adjustable air cushion at each end.

Where the Airtac SC50 Standard Cylinder SC50X1700S Is Used
Long-Reach Material Pusher
Extends 1700 mm to push products off a wide conveyor line, with magnet sensors confirming full extension and retraction for cycle control.
Automated Gantry Pick-and-Place
Provides the long vertical stroke on a gantry system, moving a lightweight gripper between levels with sensor feedback for position verification.
Greenhouse Vent Actuator
Operates a long-throw vent or damper in a controlled environment, using the built-in magnet to signal open/closed status to the climate controller.
Is the Airtac SC50 Standard Cylinder SC50X1700S the Right Cylinder?
For applications needing less force, the 40 mm bore SC40 series provides 628 N push at 0.5 MPa; for higher force, the 63 mm bore SC63 series offers 1559 N. This 1700 mm stroke requires careful side-load management: an unsupported rod of this length is susceptible to bending under lateral forces. Use an external linear guide or a guided cylinder assembly to protect the rod bearing and ensure reliable operation. When replacing, match bore (50 mm), stroke (1700 mm), PT1/4 port thread, the built-in magnet (-S), and the basic 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 SC50X1700S FAQ
At the standard operating pressure of 0.5 MPa, the cylinder pushes with 982 N and pulls with 825 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 1767 N.
This cylinder does not hold position without live pressure and the long rod is vulnerable to side loads. Always mount an external linear guide rail or use a guided cylinder to absorb bending moments, and never rely on the air cushion as a locking mechanism.
