About the Airtac SC50 Standard Cylinder SC50X1620S
The AirTAC SC50X1620S is a double-acting tie-rod cylinder with a 50 mm bore and an extended 1620 mm non-standard stroke, built to order for applications requiring an unusually long linear reach. 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, while the 20 mm diameter piston rod and 21 mm adjustable air cushion help manage end-of-stroke deceleration even on this long travel.
This model includes the factory-installed -S magnet, allowing CMSG, DMSG, or EMSG reed and solid-state sensors to be clamped directly onto the barrel for contactless position feedback. The cylinder body length A is 150 mm, giving a total extended length of approximately 1770 mm, and it uses PT1/4 ports with an M16x1.5 rod thread. Because the stroke exceeds the 1200 mm maximum standard stroke for bore 50, this is a non-standard made-to-order configuration.

Where the Airtac SC50 Standard Cylinder SC50X1620S Is Used
Long-Reach Material Transfer
Pushes or pulls light pallets, trays, or components across wide conveyor gaps or between distant stations where a 1620 mm stroke eliminates the need for complex multi-stage actuators.
Automated Gantry Tool Positioning
Moves a sensor head, spray nozzle, or marking tool along a long linear axis on a light gantry, with the built-in magnet providing end-of-travel position confirmation via DMSG sensors.
Vertical Blind or Vent Actuation
Operates high-level louvres, dampers, or blinds in agricultural or industrial buildings, using the full 1620 mm stroke to open and close large vent panels from a single pivot point.
Is the Airtac SC50 Standard Cylinder SC50X1620S the Right Cylinder?
For a 50 mm bore at this stroke length, verify that the 982 N push force at 0.5 MPa matches your moving mass and cycle time. If you need more force, stepping up to a 63 mm bore provides 1559 N at the same pressure; for a lighter, more compact solution the 40 mm bore offers 628 N. At 1620 mm stroke the unsupported rod is highly susceptible to bending under side load—always use an external linear guide or a guided cylinder assembly to protect the rod bearing and seals.
When replacing an existing cylinder, match five points exactly: bore (50 mm), stroke (1620 mm), port thread (PT1/4), the built-in magnet (-S) for sensor compatibility, and the basic mounting configuration. This SC tie-rod cylinder is shorter than an ISO 15552 profile and is not dimensionally interchangeable with ISO 15552 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 SC50X1620S FAQ
At 0.5 MPa the cylinder pushes with 982 N and pulls with 825 N. At 0.7 MPa the push force increases to 1374 N, and at the maximum operating pressure of 0.9 MPa it reaches 1767 N. The theoretical maximum at 1.0 MPa is 200 kgf. Always apply a safety factor for real-world dynamic loads.
No. At 1620 mm stroke the 20 mm diameter rod is long and slender, and any side load or misalignment will cause rod bending, premature bearing wear, and seal failure. You must install an external linear guide, rod support, or use a guided cylinder configuration to absorb transverse forces and protect the cylinder.
