About the Airtac SC50 Standard Cylinder SC50X260
The AirTAC SC50X260 is a 50 mm bore double-acting pneumatic cylinder delivering a 260 mm stroke. At 0.5 MPa it provides 982 N of push force and 825 N pull force, rising to 1767 N push at the 0.9 MPa maximum operating pressure. Its 20 mm diameter piston rod with M16x1.5 male thread and 21 mm adjustable air cushion make it a capable mid-range actuator.
This tie-rod cylinder has a compact body length A of 150 mm, giving an approximate extended length of 410 mm. The standard PT1/4 port and TPU seals suit filtered-air operation from -20 to +70 °C. With a 260 mm stroke it stays within the 1200 mm maximum standard stroke for bore 50, so it is a standard-stroke model available from AirTAC inventory.

Where the Airtac SC50 Standard Cylinder SC50X260 Is Used
Package Diverting
The 260 mm stroke and 982 N push force at 0.5 MPa reliably shift cartons or totes on a conveyor lane, with adjustable cushion to soften end-of-stroke impact.
Clamping & Fixturing
Delivers steady holding force for machining or welding fixtures. The tie-rod construction handles repetitive cycling in dusty workshop air when filtered to 40 µm.
Lift-Assist Gates
Operates a 260 mm travel lift gate or stop on gravity roller conveyors. The double-acting design provides powered retraction as well as extension for positive control.
Is the Airtac SC50 Standard Cylinder SC50X260 the Right Cylinder?
Choose the SC50X260 when your application needs roughly 1000 N of force at typical shop air. If you need more force, stepping up to the SC63 bore delivers 1559 N push at 0.5 MPa; if you need less, the SC40 bore provides 628 N. At 260 mm of stroke the 20 mm rod is well supported inside the barrel, but if the load applies a side force or the rod must push off-axis, add an external linear guide or switch to a guided cylinder to prevent rod bearing wear.
For a direct replacement, match five points: 50 mm bore, 260 mm stroke, PT1/4 port thread, the specific mounting accessory (this model is basic, no bracket), and the magnet option (this model has no built-in magnet). The SC is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile 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 SC50X260 FAQ
At 0.5 MPa (≈73 psi) the SC50X260 produces 982 N push and 825 N pull. At the maximum operating pressure of 0.9 MPa, push force reaches 1767 N. The theoretical maximum at 1.0 MPa is 200 kgf (≈1961 N) push.
No. The AirTAC SC series is a tie-rod cylinder with a shorter body length than an ISO 15552 cylinder. It is not dimensionally interchangeable. It directly replaces another AirTAC SC50 cylinder with the same stroke, port thread, mounting, and magnet configuration.
