About the Airtac SC50 Standard Cylinder SC50X153
The AirTAC SC50X153 is a double-acting single-rod pneumatic cylinder delivering 982 N of push force and 825 N of pull force at 0.5 MPa. With a 50 mm bore and a non-standard 153 mm stroke, it suits applications needing a specific travel length not covered by the standard stroke list. The 20 mm diameter piston rod and M16x1.5 rod thread provide solid mechanical connection.
This tie-rod cylinder uses a PT1/4 port and features an adjustable pneumatic cushion (21 mm length) at both ends to decelerate the piston smoothly. The total extended body length is approximately 303 mm (150 mm body length A + 153 mm stroke). Operating pressure ranges from 0.15 to 1.0 MPa, with a maximum push force of 1767 N at 0.9 MPa.

Where the Airtac SC50 Standard Cylinder SC50X153 Is Used
Product Diverting
Pushes packages off a conveyor line with 982 N of force at standard plant pressure, ideal for medium-weight carton handling.
Clamping & Fixturing
Secures workpieces in CNC or welding jigs with a compact 153 mm stroke, providing consistent clamping force without over-travel.
Agricultural Gate Actuation
Operates chutes or sorting gates on harvesting equipment, where the specific 153 mm throw matches the mechanism's geometry.
Is the Airtac SC50 Standard Cylinder SC50X153 the Right Cylinder?
For applications needing slightly less force, consider stepping down to the 40 mm bore (628 N push at 0.5 MPa). If the 982 N push force is marginal, the 63 mm bore offers 1559 N at the same pressure. This 153 mm stroke is non-standard; verify lead time for made-to-order production. For strokes over 300 mm or applications with side load, use an external guide or a guided cylinder to protect the rod bearing from bending moments.
When replacing an existing cylinder, match five key points: bore (50 mm), stroke (153 mm), port thread (PT1/4), mounting style (basic, no bracket), and confirm whether a magnet is needed (this model has no built-in magnet). The SC series is a tie-rod design 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 SC50X153 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 AirTAC SC series is a tie-rod cylinder with a shorter body length than an ISO 15552 cylinder. It is not dimensionally interchangeable. Only replace with another AirTAC SC tie-rod cylinder of the same bore, stroke, port, and mounting configuration.
