About the Airtac SC50 Standard Cylinder SC50X1850S
The AirTAC SC50X1850S is a double-acting single-rod pneumatic cylinder with a 50 mm bore and an extra-long 1850 mm non-standard stroke, built to order for applications requiring extended linear travel. It delivers a push force of 982 N at 0.5 MPa and up to 1767 N at the maximum operating pressure of 0.9 MPa, driven by a 20 mm diameter piston rod with M16x1.5 male threads.
This model includes a factory-installed -S magnet embedded in the piston, allowing direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors on the tie-rod barrel for precise position feedback. The 1850 mm stroke exceeds the standard 1200 mm maximum for 50 mm bore SC cylinders, making it a made-to-order item with a total extended body length of 2000 mm (150 mm body length A + 1850 mm stroke).

Where the Airtac SC50 Standard Cylinder SC50X1850S Is Used
Long-Stroke Material Pusher
The 1850 mm stroke is ideal for pushing heavy bins or pallets across wide conveyor transfers in distribution centers, with the built-in magnet enabling end-of-stroke confirmation.
Automated Spray Boom Actuation
Provides the extended reach needed for raising and lowering spray booms in agricultural or industrial coating equipment, where sensor feedback ensures consistent positioning.
Vertical Panel Lift Assist
Delivers 982 N of push force to raise large access panels or machine guards over a long 1850 mm travel distance, with magnetic sensors confirming the open and closed states.
Is the Airtac SC50 Standard Cylinder SC50X1850S the Right Cylinder?
Select the SC50X1850S when your application demands a long 1850 mm linear stroke with a mid-range force of 982 N at standard shop air. If your load requires more force, step up to the 63 mm bore SC63 series, which provides 1559 N of push at the same 0.5 MPa pressure. For lower force needs, the 40 mm bore SC40 series offers 628 N.
For any stroke of 300 mm or more, and especially for this 1850 mm non-standard stroke, carefully evaluate side-loading conditions. The 20 mm rod is susceptible to bending under lateral forces when fully extended. Always use an external linear guide rail or rod support to absorb side loads and protect the rod bearing from premature wear. For a direct replacement, match the 50 mm bore, 1850 mm stroke, PT port thread, and the -S magnet option exactly with another AirTAC SC series cylinder.
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 SC50X1850S 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, but the recommended working range is 0.15–1.0 MPa.
A stroke of 1850 mm on a 20 mm rod creates a high risk of buckling and side-load damage. The cylinder must not absorb lateral forces directly. Install an external linear guide rail parallel to the cylinder to carry the load, and ensure the rod is only subjected to axial push/pull forces.
