About the Airtac SC50 Standard Cylinder SC50X150SCB
The SC50X150SCB is a double-acting pneumatic cylinder delivering 982 N of push force at 0.5 MPa (1374 N at 0.7 MPa), making it a capable mid-range actuator for pressing, clamping, and material-handling tasks. Its 150 mm stroke is well within the 1200 mm maximum for the 50 mm bore, and the 20 mm diameter piston rod provides good column strength for straight-line pushing.
This model is factory-configured with a built-in magnet (-S) for barrel-mounted CMSG/DMSG/EMSG sensors and a rear double clevis mount (CB, part F-SC50CB) that allows the cylinder to pivot during operation. The adjustable air cushion at each end decelerates the piston smoothly, reducing end-of-stroke shock.

Where the Airtac SC50 Standard Cylinder SC50X150SCB Is Used
Part Rejection Gate
The rear clevis mount allows the SC50X150SCB to pivot as it extends 150 mm to divert rejected parts off a conveyor line, with magnetic sensors confirming gate position.
Clamping Fixture
Delivers 1374 N of clamping force at 0.7 MPa to hold workpieces during machining or welding. The double clevis accommodates fixture articulation.
Bin Tipper Actuator
Pivots a small bin or hopper through a controlled arc. The adjustable cushion prevents jarring at the end of the 150 mm stroke, protecting the load.
Is the Airtac SC50 Standard Cylinder SC50X150SCB the Right Cylinder?
Choose the SC50 when your application needs roughly 1000 N of force from standard shop air. If you require more force, stepping up to the SC63 provides 1559 N push at 0.5 MPa; if space is tight and less force is acceptable, the SC40 delivers 628 N. The 150 mm stroke is standard, but for strokes over 300 mm on this bore, evaluate side-load conditions and consider an external guide to protect the rod bearing from bending moments.
For a direct replacement, match these five points: 50 mm bore, 150 mm stroke, PT port thread, rear double clevis (CB) mounting, and the built-in magnet (-S) for position sensing. This tie-rod cylinder 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 SC50X150SCB FAQ
At the standard operating pressure of 0.5 MPa, this cylinder provides 982 N extending (push) and 825 N retracting (pull). At 0.7 MPa, push force increases to 1374 N. The theoretical maximum force 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 of the same bore and stroke. It is not dimensionally interchangeable. Replace only with another AirTAC SC tie-rod cylinder matching the bore, stroke, PT ports, CB mount, and magnet option.
