About the Airtac SC50 Standard Cylinder SC50X2000S
The AirTAC SC50X2000S is a double-acting tie-rod cylinder with a 50 mm bore and an extra-long 2000 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 extended linear travel. The piston rod is 20 mm in diameter with an M16x1.5 male thread, and the cylinder generates a theoretical push force of 1767 N at the maximum operating pressure of 0.9 MPa.
Equipped with the -S suffix, this model includes a built-in magnet embedded in the piston. This allows for direct, non-contact position sensing by clamping compatible CMSG, DMSG, or EMSG reed or solid-state sensors onto the cylinder's tie-rod barrel. The adjustable pneumatic cushion at both ends, with a 21 mm cushion length, decelerates the piston to reduce end-of-stroke impact, protecting the cylinder and the machine structure.

Where the Airtac SC50 Standard Cylinder SC50X2000S Is Used
Long-Reach Material Handling
Operates a long-stroke pusher or kicker on a conveyor line, transferring products across a wide gap where a standard-stroke cylinder cannot reach.
Extended Clamping & Fixturing
Provides the long travel needed to move a clamp or fixture completely clear of a large workpiece for unobstructed loading and unloading in a machining center.
Grain Door or Gate Actuation
Opens and closes a large sliding gate on a hopper or chute, using the full 2000 mm stroke for complete material flow control in an agricultural setting.
Is the Airtac SC50 Standard Cylinder SC50X2000S the Right Cylinder?
Selecting the SC50X2000S means committing to a non-standard stroke for a specific long-travel requirement. If the force is insufficient, stepping up to a 63 mm bore increases the push force from 1767 N to 2805 N at 0.9 MPa. Conversely, if a shorter stroke within the 1200 mm standard range is acceptable, a standard SC50 model will offer a faster lead time.
For a 2000 mm stroke, managing rod deflection and side loading is critical. The 20 mm rod is highly susceptible to bending under compressive loads or lateral forces when fully extended. It is mandatory to use an external linear guide or a self-aligning rod coupler to constrain the load and prevent rod bearing failure. When replacing this cylinder, match the 50 mm bore, 2000 mm stroke, PT port thread, built-in magnet, and basic mounting configuration.
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 SC50X2000S FAQ
At 0.5 MPa, the theoretical push force is 982 N and the pull force is 825 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 1767 N. The theoretical maximum force at 1.0 MPa is 200 kgf.
A 20 mm diameter rod extended to 2000 mm is at high risk of buckling and bending under side loads. You must guide the load externally with a linear rail or rod guide system. The cylinder should only provide the push/pull force, not support the weight or lateral forces of the load.
