About the Airtac SC50 Standard Cylinder SC50X170
The SC50X170 is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, delivering a push force of 982 N at 0.5 MPa and up to 1767 N at the maximum operating pressure of 0.9 MPa. With a 50 mm bore, 20 mm piston rod, and a 170 mm stroke, it provides a balanced combination of force and reach for medium-duty linear actuation tasks.
This model features a body length A of 150 mm, resulting in a total extended length of approximately 320 mm. The adjustable air cushion at each end (21 mm cushion length) decelerates the piston smoothly, reducing end-of-stroke impact. Standard PT1/4 ports and an M16x1.5 rod thread ensure straightforward pneumatic connections and tooling attachment.

Where the Airtac SC50 Standard Cylinder SC50X170 Is Used
Part Rejection Gates
Provides the rapid linear stroke needed to divert products on a conveyor line, using the 982 N push force to reliably actuate a gate or flipper mechanism.
Clamping & Holding Fixtures
Delivers consistent clamping pressure for workpieces in CNC machining or welding jigs, where the 170 mm stroke offers ample clearance for part loading and unloading.
Box Taping & Case Sealing
Actuates the compression rollers or taping heads in case sealers, applying uniform force across the 170 mm stroke to securely close and seal shipping cartons.
Is the Airtac SC50 Standard Cylinder SC50X170 the Right Cylinder?
Select the SC50X170 when your application requires around 982 N of force at standard plant pressure. If you need more force, stepping up to the 63 mm bore (SC63 series) provides 1559 N at the same 0.5 MPa. For lighter, more compact needs, the 40 mm bore (SC40) delivers 628 N. Always match the bore, 170 mm stroke, PT1/4 port thread, and basic mounting when replacing an existing unit. For strokes of 170 mm, the standard 20 mm rod is generally rigid, but avoid direct side loading; use an external guide if the load is not perfectly axial.
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 SC50X170 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 increases to 1767 N. The theoretical maximum force at 1.0 MPa is 200 kgf.
It can replace another AirTAC SC series 50mm bore, 170mm stroke cylinder directly. For other brands, you must verify the tie-rod mounting dimensions, body length (A=150 mm), PT1/4 port thread, and M16x1.5 rod thread, as the SC series is not dimensionally interchangeable with ISO 15552 profile cylinders.
