About the Airtac SC50 Standard Cylinder SC50X1540S
The AirTAC SC50X1540S is a double-acting single-rod pneumatic cylinder with a 50 mm bore and an extended 1540 mm stroke, built for long-reach linear tasks. Its 20 mm diameter piston rod delivers a theoretical push force of 1767 N at the maximum operating pressure of 0.9 MPa (200 kgf at 1.0 MPa), while the adjustable air cushion (21 mm length) decelerates the piston smoothly at each end of travel.
This model includes a built-in magnet (-S suffix), allowing CMSG, DMSG, or EMSG reed and solid-state sensors to be clamped directly onto the tie-rod barrel for non-contact position sensing. Because the 1540 mm stroke exceeds the standard maximum of 1200 mm for 50 mm bore, this is a non-standard, made-to-order configuration. The body length A is 150 mm, giving a total extended length of approximately 1690 mm.

Where the Airtac SC50 Standard Cylinder SC50X1540S Is Used
Long-Reach Material Handling
Extends across wide conveyor gaps to push or divert cartons, using the 1540 mm stroke. The built-in magnet confirms end-of-stroke position in automated sortation lines.
Automated Gluing & Dispensing
Positions a dispensing head deep into a fixture with consistent 0.5 MPa thrust. Sensor feedback from the -S magnet ensures the head is fully retracted before the next cycle.
Greenhouse Vent Actuation
Opens and closes high-level roof vents with a 1540 mm linear throw. The TPU seals handle the -20 to +70 °C temperature range, and the adjustable cushion prevents hard stops.
Is the Airtac SC50 Standard Cylinder SC50X1540S the Right Cylinder?
Select the SC50 when your application needs roughly 982 N of push force at 0.5 MPa. If you require more force, stepping up to the 63 mm bore provides 1559 N at the same pressure; for a lighter, more compact solution, the 40 mm bore delivers 628 N. Always match a replacement cylinder across five points: 50 mm bore, 1540 mm stroke, PT port thread, basic mounting (no bracket), and the -S magnet for sensor compatibility.
With a stroke of 1540 mm, the 20 mm rod is susceptible to bending under side loads. For this long-stroke configuration, use an external linear guide or a guided cylinder assembly to protect the rod bearing and ensure reliable, straight-line motion. 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 SC50X1540S FAQ
At 0.7 MPa (7 bar) operating pressure, the theoretical push force on the piston rod extension stroke is 1374 N. The pull force on the retraction stroke is 825 N at 0.5 MPa (confirm retraction force at 0.7 MPa from the datasheet).
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 accessories are not interchangeable. It is a direct replacement only for another AirTAC SC50 tie-rod cylinder with matching bore, stroke, PT ports, basic mount, and -S magnet.
