About the Airtac SC50 Standard Cylinder SC50X175CB
The SC50X175CB is a 50 mm bore, 175 mm stroke double-acting pneumatic cylinder from the AirTAC SC tie-rod series. Configured with a rear double clevis (CB) mount, it delivers a theoretical push force of 982 N at 0.5 MPa and can reach 1767 N at the maximum operating pressure of 0.9 MPa, making it a capable mid-range actuator.
This model uses a 20 mm diameter piston rod with an M16x1.5 male thread and PT1/4 ports. The 21 mm adjustable air cushion at each end decelerates the piston smoothly, protecting end-cap components. Its body length A is 150 mm, giving a total extended length of approximately 325 mm.

Where the Airtac SC50 Standard Cylinder SC50X175CB Is Used
Agricultural Implement Actuation
Controls chute deflectors or bin gates on harvesters and spreaders. The CB clevis mount handles the pivoting motion required by linkage-operated mechanisms.
Diverter Gate Control
Operates a pivoting diverter arm on a conveyor line to sort packages by destination. The 175 mm stroke provides sufficient travel for a full gate swing.
Welding Fixture Clamping
Drives a pivoting clamp arm in a robotic welding cell. The 825 N pull force at 0.5 MPa secures the workpiece, and the adjustable cushion prevents impact vibration.
Is the Airtac SC50 Standard Cylinder SC50X175CB the Right Cylinder?
For applications needing more force, stepping up to a 63 mm bore provides 1559 N push at 0.5 MPa. If a lower force profile is acceptable, the 40 mm bore delivers 628 N. The CB rear double clevis allows the cylinder body to pivot during operation, ideal for articulating linkages. Ensure the stroke is fully supported if side loads are present.
To replace this cylinder, match five key points: 50 mm bore, 175 mm stroke, PT1/4 port thread, the CB rear double clevis mounting (part F-SC50CB), and the standard non-magnetic piston. 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 SC50X175CB FAQ
At 0.7 MPa operating pressure, the theoretical pulling force on the retract stroke is 1374 N. The push force at the same pressure is 1374 N. These values are based on the 50 mm bore and 20 mm rod diameter.
No. The AirTAC SC series is a tie-rod cylinder with a shorter overall body length than an ISO 15552 cylinder. The mounting dimensions and body profile are not interchangeable. You must match another AirTAC SC tie-rod cylinder with the same bore, stroke, and CB mount.
