About the Airtac SC50 Standard Cylinder SC50X167
The SC50X167 is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, combining a 50 mm bore with a 167 mm stroke. At 0.5 MPa it generates 982 N of push force and 825 N of pull force, making it a capable mid-range actuator for pressing, clamping, and material-transfer tasks.
This model features a 20 mm diameter piston rod with M16x1.5 male threads and PT1/4 ports. The adjustable air cushion at each end (21 mm cushion length) decelerates the piston smoothly, reducing end-of-stroke impact. The body length A is 150 mm, giving a total extended length of approximately 317 mm.

Where the Airtac SC50 Standard Cylinder SC50X167 Is Used
Part Transfer
Pushes or lifts components between conveyor lanes or indexing stations with 982 N of force at standard shop air.
Light Assembly Press
Provides controlled insertion force for bearings, bushings, or dowels in manual or semi-automated assembly fixtures.
Clamping & Holding
Actuates a toggle or direct clamp to secure workpieces during machining, welding, or gluing operations.
Is the Airtac SC50 Standard Cylinder SC50X167 the Right Cylinder?
For applications needing more force, the SC63 delivers 1559 N push at 0.5 MPa from the same 167 mm stroke. If a lighter, more compact cylinder is sufficient, the SC40 provides 628 N. This SC50X167 is a basic configuration with TPU seals (-20 to +70 °C) and PT threads.
When replacing an existing unit, match five points: 50 mm bore, 167 mm stroke, PT1/4 port thread, basic (no bracket) mounting, and no magnet. 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 SC50X167 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, push force reaches 1767 N. The theoretical maximum at 1.0 MPa is 200 kgf.
No. The SC50X167 is a double-acting cylinder and will drift or drop if pressure is lost or the directional valve is centered. To hold a position without live pressure, add a pilot-operated check valve or an external rod lock.
