About the Airtac SC50 Standard Cylinder SC50X75CA
The SC50X75CA is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, combining a 50 mm bore with a 75 mm stroke. It generates a push force of 982 N at 0.5 MPa and 1767 N at the maximum operating pressure of 0.9 MPa, driven by a 20 mm diameter piston rod with M16x1.5 male threads.
This model is configured with a rear single clevis (CA) mounting, part F-SC50CA, which allows the cylinder body to pivot during operation, ideal for articulated linkages. The standard PT1/4 port and adjustable air cushion at both ends ensure smooth deceleration, while the TPU seals provide reliable service in ambient temperatures from -20 to +70 °C.

Where the Airtac SC50 Standard Cylinder SC50X75CA Is Used
Clamping & Fixturing
The 982 N force at 0.5 MPa makes this cylinder well-suited for pneumatic clamping fixtures on milling or drilling stations, where the rear clevis mount allows the body to self-align as the clamp engages.
Linkage Actuation
With its CA rear clevis, this cylinder easily integrates into articulated linkages on agricultural machinery like chute diverters or hatch lifts, pivoting smoothly as the rod extends and retracts through the 75 mm stroke.
Part Diverter Gates
Use the SC50X75CA to actuate diverter gates on light-to-medium conveyor lines. The 20 mm rod and clevis mount handle the repetitive swinging motion, directing packages or components reliably.
Is the Airtac SC50 Standard Cylinder SC50X75CA the Right Cylinder?
For applications needing more force, stepping up to the 63 mm bore SC63 series provides 1559 N of push at 0.5 MPa. If a lower force profile and lighter weight are preferred, the 40 mm bore delivers 628 N. The 75 mm stroke is a standard length for this bore, well within the 1200 mm maximum.
When replacing an existing cylinder, match five key points: 50 mm bore, 75 mm stroke, PT1/4 port thread, the CA rear clevis mounting, and confirm whether a magnet is required (this model has no built-in magnet). The SC is a tie-rod design, shorter than an ISO 15552 cylinder, so dimensional interchangeability should be verified against another AirTAC SC unit.
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 SC50X75CA FAQ
At the standard operating pressure of 0.5 MPa, the cylinder pushes with 982 N and pulls with 825 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 1767 N.
Yes. The CA suffix designates a rear single clevis mount (part F-SC50CA). This allows the cylinder body to pivot on a single pin at the rear cap, accommodating angular movement as the rod extends and retracts. It must be paired with a rod-end clevis or spherical joint for proper alignment.
