About the Airtac SC50 Standard Cylinder SC50X1350STC
The AirTAC SC50X1350STC is a double-acting pneumatic cylinder delivering 982 N of push force at 0.5 MPa and up to 1767 N at the maximum operating pressure of 0.9 MPa. This model combines a 50 mm bore with an extended 1350 mm stroke, making it suitable for long-reach transfer and material-handling tasks where a compact tie-rod body is required.
This configuration includes a built-in magnet for barrel-mounted CMSG/DMSG/EMSG sensors and a centre trunnion mount (TC) supplied with the TCM1 bracket (F-SC50TC), allowing the cylinder to pivot during actuation. The 20 mm diameter piston rod and 21 mm adjustable air cushion at each end help manage end-of-stroke deceleration, though for a stroke of this length, external guides are strongly recommended to protect the rod from side-load bending.

Where the Airtac SC50 Standard Cylinder SC50X1350STC Is Used
Long-Stroke Part Transfer
The 1350 mm reach moves components between distant conveyor stations. The centre trunnion mount lets the cylinder body pivot, accommodating the arc of a long transfer arm.
Automated Gluing & Dispensing
Provides a steady, straight-line stroke for moving a dispensing head across large panels. The built-in magnet allows end-of-stroke position confirmation via reed sensors.
Vertical Lift Gate Actuation
Operates tall lift gates or hopper doors where a long, guided stroke is needed. The adjustable air cushion softens the stop at both ends, reducing wear on the gate mechanism.
Is the Airtac SC50 Standard Cylinder SC50X1350STC the Right Cylinder?
Choose the SC50 when your application needs roughly 1000 N of force at standard shop air; the next step up is the SC63, which provides 1559 N at 0.5 MPa. For this 1350 mm stroke, which exceeds the 1200 mm maximum standard stroke for the 50 mm bore, the cylinder is a non-standard, made-to-order item. Always support long strokes with an external guide rail or rod-alignment coupler to prevent bearing wear and rod buckling under side load.
To replace an existing unit, match five points: 50 mm bore, 1350 mm stroke, PT port thread, centre trunnion (TC) mounting, and the built-in magnet (-S). 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 SC50X1350STC FAQ
At 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. The theoretical maximum force at 1.0 MPa is 200 kgf.
For strokes over 300 mm, and especially at 1350 mm, do not allow the rod to take side loads directly. Install an external linear guide rail parallel to the cylinder, or use a rod-alignment coupler with a floating joint, to prevent bending moment on the rod bearing and premature seal failure.
