About the Airtac SC50 Standard Cylinder SC50X40CA
The AirTAC SC50X40CA is a double-acting tie-rod cylinder with a 50 mm bore and a 40 mm stroke, fitted with a rear single clevis (CA) mount for pivoting applications. At 0.5 MPa it delivers 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 (21 mm length) decelerates the piston at end-of-stroke to reduce impact. The CA clevis (accessory F-SC50CA) allows the cylinder body to pivot, accommodating angular misalignment in the machine frame.

Where the Airtac SC50 Standard Cylinder SC50X40CA Is Used
Linkage Actuation
The rear single clevis mount allows the SC50X40CA to pivot freely, making it ideal for actuating linkages, levers, and dump mechanisms on agricultural equipment where the cylinder must follow an arc.
Part Diverter Gate
With a short 40 mm stroke and 982 N push force, this cylinder quickly shifts a diverter gate on a conveyor line, routing packages between lanes with a clean, fast motion.
Clamp & Fixture Pivot
Used on welding or assembly fixtures, the clevis-mounted SC50X40CA swings a clamping arm into place. The adjustable cushion prevents hammering at the end of the short, rapid stroke.
Is the Airtac SC50 Standard Cylinder SC50X40CA the Right Cylinder?
Choose the SC50 bore when your application needs roughly 1000 N of force at standard plant air pressure. If you need more force, step up to the SC63 which provides 1559 N push at 0.5 MPa; for a lighter, more compact solution the SC40 delivers 628 N. The 40 mm stroke is a standard length within the SC50's 1200 mm maximum.
For replacement, match five points: 50 mm bore, 40 mm stroke, PT port thread, rear single clevis (CA) mounting, and no magnet. This cylinder is not ISO 15552 compatible—it is a tie-rod design and is shorter than an equivalent ISO 15552 cylinder. Only substitute with another AirTAC SC50 tie-rod unit of identical configuration.
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 SC50X40CA FAQ
At 0.5 MPa (5 bar) the cylinder produces 982 N extending (push) and 825 N retracting (pull). 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 and its body length (A=150 mm) is shorter than an ISO 15552 profile cylinder of the same bore. Mounting dimensions and accessory interfaces differ. Replace only with another AirTAC SC50 tie-rod cylinder matching the bore, stroke, PT port, and CA clevis mount.
