About the Airtac SC50 Standard Cylinder SC50X150CA
The SC50X150CA is a 50 mm bore double-acting pneumatic cylinder with a 150 mm stroke, factory-configured with a rear single clevis (CA) for pivoting applications. At 0.5 MPa it generates 982 N pushing force and 825 N pulling force, rising to 1767 N push at the 0.9 MPa maximum operating pressure.
This model uses a 20 mm diameter piston rod with an M16x1.5 male thread and PT1/4 ports. The adjustable air cushion at each end (21 mm length) decelerates the piston smoothly, and the 150 mm body length A keeps the overall envelope compact for machinery with limited rear clearance.

Where the Airtac SC50 Standard Cylinder SC50X150CA Is Used
Dump Trailer Gate Actuation
The rear clevis mount lets the cylinder pivot as it opens and closes a hopper or trailer gate, handling the 982 N push force needed to move bulk material loads.
Clamping & Fixturing
Delivers consistent 825 N pull force for draw-bar clamping on CNC fixtures, with the clevis absorbing misalignment during the 150 mm stroke.
Sorting Gate Diverter
Swings a diverter gate on a conveyor line. The adjustable cushion prevents hard stops at each end, protecting the gate and cylinder from impact damage.
Is the Airtac SC50 Standard Cylinder SC50X150CA the Right Cylinder?
Choose the SC50X150CA when your application needs a pivoting cylinder mount—the rear clevis (F-SC50CA) allows the cylinder to swing as it strokes. If you need higher force, the SC63 bore provides 1559 N push at 0.5 MPa; for a lighter, more compact solution the SC40 bore delivers 628 N. The 150 mm stroke is well within the 1200 mm maximum standard stroke for bore 50.
For a direct replacement, match five points: 50 mm bore, 150 mm stroke, PT1/4 port thread, rear single clevis mounting, and the standard TPU seal. This cylinder is not dimensionally interchangeable with ISO 15552 profile cylinders—it is a tie-rod design with a shorter overall length.
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 SC50X150CA FAQ
At the standard 0.5 MPa operating pressure, the cylinder produces 982 N extending (push) and 825 N retracting (pull). At the maximum 0.9 MPa operating pressure, the push force increases to 1767 N.
No. The AirTAC SC series is a tie-rod cylinder with a shorter body length than an ISO 15552 profile cylinder, so mounting dimensions and tie-rod spacing differ. It is a direct replacement only for another AirTAC SC50 cylinder with matching stroke, port thread, and rear clevis mount.
