About the Airtac SC50 Standard Cylinder SC50X1500
The AirTAC SC50X1500 is a double-acting, single-rod pneumatic cylinder with a 50 mm bore and an extended 1500 mm stroke. This non-standard stroke length exceeds the standard maximum of 1200 mm for the 50 mm bore, making it a made-to-order unit for applications requiring an exceptionally long reach. At the standard operating pressure of 0.9 MPa, it generates a theoretical push force of 1767 N, driven by a 20 mm diameter piston rod.
The cylinder body length A is 150 mm, resulting in a total extended length of approximately 1650 mm. It features an adjustable pneumatic cushion (21 mm length) at both ends to decelerate the piston smoothly, reducing end-of-stroke impact. This model uses a PT1/4 port thread and an M16x1.5 rod thread, with the standard TPU seal material for an operating temperature range of -20 to +70 °C.

Where the Airtac SC50 Standard Cylinder SC50X1500 Is Used
Long-Reach Material Pushing
Ideal for ejector or pusher stations on wide conveyor lines where a 1500 mm stroke is needed to move large boxes or pallets completely off the belt without a complex multi-stage actuator.
Vertical Panel Access
Used to raise and lower heavy access panels or machine guards over a long vertical distance, where the 1767 N force at 0.9 MPa can reliably lift a large safety shield.
Extended Tooling Transfer
Transfers a tooling plate or welding fixture between distant stations in a linear automation cell, leveraging the tie-rod construction for rigid, repeatable long-stroke motion.
Is the Airtac SC50 Standard Cylinder SC50X1500 the Right Cylinder?
Select the SC50X1500 when the 50 mm bore provides the right force envelope, delivering 982 N of push force at 0.5 MPa. If you need more force, stepping up to the SC63 bore provides 1559 N at the same pressure; for a lighter, more compact solution, the SC40 bore offers 628 N. For this 1500 mm stroke length, managing side loads and rod deflection is critical. An unsupported 20 mm rod at full extension is highly susceptible to bending under lateral force. Always use an external linear guide or rod support to absorb side loads and protect the rod bearings and piston seals from premature wear.
For a direct replacement, match these five key specifications: a 50 mm bore, a 1500 mm stroke, a PT1/4 port thread, the basic (no bracket) mounting configuration, and the absence of a built-in magnet. This ensures dimensional and functional interchangeability with another AirTAC SC tie-rod cylinder of the same configuration.

- ✓ 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 SC50X1500 FAQ
The theoretical push force on the piston rod extension is 982 N at 0.5 MPa, 1374 N at 0.7 MPa, and reaches 1767 N at the maximum operating pressure of 0.9 MPa. The pull force on retraction is lower due to the rod area, delivering 825 N at 0.5 MPa.
A 20 mm diameter rod extended to 1500 mm is at high risk of buckling or bending under side loads. You must guide the load externally with a linear rail system or rod support. Never allow the cylinder rod to bear a lateral force directly, as this will damage the rod bearing and internal seals.
