About the Airtac SC50 Standard Cylinder SC50X1860
The AirTAC SC50X1860 is a double-acting single-rod pneumatic cylinder with a 50 mm bore and an extra-long 1860 mm stroke, built for linear applications that demand extended reach. At 0.5 MPa it generates 982 N of pushing force and 825 N pulling force, while at the maximum operating pressure of 0.9 MPa the thrust rises to 1767 N. The cylinder features a 20 mm diameter piston rod with M16x1.5 male threads, PT1/4 ports, and a 21 mm adjustable air cushion at each end to decelerate the piston smoothly.
This 1860 mm stroke exceeds the standard maximum of 1200 mm for the 50 mm bore, making it a non-standard, made-to-order configuration. The body length A is 150 mm, giving a total extended length of approximately 2010 mm. With such a long, slender rod, external guides or a guided cylinder should be considered if the load applies any side force, to prevent rod bending and premature bearing wear. The default TPU seals and NBR O-rings suit operating temperatures from -20 to +70 °C.

Where the Airtac SC50 Standard Cylinder SC50X1860 Is Used
Long-Reach Material Pusher
Pushes pallets or large boxes across wide roller conveyors where a standard-stroke cylinder falls short. The 1860 mm stroke crosses an entire conveyor zone in one motion.
Vertical Panel Lifter
Raises and lowers large sheets or panels in a gantry with guided vertical travel. The 982 N push force at 0.5 MPa lifts moderate loads, while the adjustable cushion softens the end-of-stroke stop.
Greenhouse Vent Actuator
Opens and closes long rows of roof vents. The extended 1860 mm stroke provides the wide angular throw needed, and the tie-rod design withstands humid, dusty environments when properly filtered.
Is the Airtac SC50 Standard Cylinder SC50X1860 the Right Cylinder?
Choose the SC50X1860 when you need a 50 mm bore with a stroke beyond the standard 1200 mm limit. If your force requirement is lower, stepping down to a 40 mm bore (628 N push at 0.5 MPa) can reduce air consumption; for higher force, the 63 mm bore provides 1559 N at the same pressure. This long-stroke cylinder must be protected from side loads—the 20 mm rod is unsupported over a very long distance and will bend under lateral force. Always use an external linear guide or rod-alignment coupler.
For a direct replacement, match five points: bore (50 mm), stroke (1860 mm), port thread (PT1/4), mounting style (basic, no bracket), and magnet option (none). This is a tie-rod cylinder, not an ISO 15552 profile cylinder, so it is dimensionally shorter and not interchangeable with ISO 15552 types.
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 SC50X1860 FAQ
At 0.7 MPa supply pressure, the SC50X1860 produces 1374 N of force when extending (push) and approximately 1155 N when retracting (pull). The theoretical maximum force at 1.0 MPa is 200 kgf. Always size the cylinder using the force at your minimum expected operating pressure, not the theoretical maximum.
It is strongly recommended to use an external guide or rod support for any stroke over 300 mm, and it is essential for an 1860 mm stroke. The 20 mm diameter rod is not designed to carry side loads over this length. Without guidance, side forces will bend the rod, damage the piston rod bearing, and cause premature seal failure. The cylinder should only be used for purely axial push-pull motions unless an external guide rail is fitted.
