About the Airtac SC50 Standard Cylinder SC50X190
The SC50X190 is a double-acting pneumatic cylinder with a 50 mm bore and 190 mm stroke, delivering a push force of 982 N at 0.5 MPa and up to 1767 N at 0.9 MPa. The 20 mm diameter piston rod and 21 mm adjustable air cushion provide reliable deceleration, making it suitable for medium-force linear tasks.
With a compact body length of 150 mm (A dimension), the total extended length is approximately 340 mm. This model uses PT1/4 ports and standard TPU seals for operation in temperatures from -20 to +70 °C. As a genuine AirTAC tie-rod cylinder, it offers consistent performance for industrial automation.

Where the Airtac SC50 Standard Cylinder SC50X190 Is Used
Part Rejection Gates
Provides the 982 N push force at 0.5 MPa needed to divert medium-weight packages or components off a conveyor line with a 190 mm stroke.
Clamping Fixtures
Delivers consistent clamping pressure for woodworking or light metal fabrication jigs, where the 20 mm rod offers good rigidity over the 190 mm stroke.
Bin Tipping Stations
Actuates a 190 mm stroke to tilt small bins or hoppers, using the adjustable cushion to smoothly decelerate the load at the end of travel.
Is the Airtac SC50 Standard Cylinder SC50X190 the Right Cylinder?
For applications needing slightly more force, the 63 mm bore SC63 series provides 1559 N at 0.5 MPa. If space is a constraint and less force is acceptable, the 40 mm bore delivers 628 N. Always match replacement cylinders on five key points: bore, stroke, port thread (PT), mounting accessory, and magnet option.
At 190 mm, this stroke is within the standard range for the 50 mm bore, which supports strokes up to 1200 mm. While side loads are less critical at this length, avoid direct lateral force on the rod. For guided motion, consider an external linear guide or a dual-rod cylinder.
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 SC50X190 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 reaches 1767 N. The theoretical maximum at 1.0 MPa is 200 kgf.
No. The SC series is a tie-rod cylinder and is shorter than a standard ISO 15552 cylinder, so it is not dimensionally interchangeable. It is a direct replacement for another AirTAC SC50 cylinder with the same stroke, port thread, and mounting type.
