About the Airtac SC50 Standard Cylinder SC50X115S
The SC50X115S is a double-acting tie-rod cylinder delivering 982 N of push force at 0.5 MPa and up to 1767 N at the maximum operating pressure of 0.9 MPa. Its 115 mm stroke suits medium-reach clamping, pressing, and material-transfer tasks, while the 20 mm diameter piston rod provides robust resistance to bending.
This model includes a built-in magnet (-S suffix), allowing CMSG, DMSG, or EMSG reed and solid-state sensors to be clamped directly onto the barrel for non-contact position sensing. The adjustable air cushion at each end (21 mm cushion length) decelerates the piston smoothly, reducing impact noise and wear at the end of every cycle.

Where the Airtac SC50 Standard Cylinder SC50X115S Is Used
Conveyor Diverter Gates
The 115 mm stroke and 982 N push force reliably actuate diverter gates on packaging and sortation conveyors, with the built-in magnet providing end-of-stroke confirmation to the PLC.
Automated Clamping Fixtures
Delivers consistent clamping force for CNC machining fixtures and welding jigs. The magnetic piston enables easy integration of sensors for clamp/unclamp verification.
Pallet Stop Mechanisms
Ideal for end-of-line pallet stops in automated warehouses. The adjustable cushion absorbs the kinetic energy of moving loads, protecting the cylinder and the stop assembly.
Is the Airtac SC50 Standard Cylinder SC50X115S the Right Cylinder?
For applications needing more force, the 63 mm bore SC63 series provides 1559 N of push force at 0.5 MPa. If a lighter, more compact actuator is preferred, the 40 mm bore SC40 series delivers 628 N. When replacing an existing cylinder, match five key points: 50 mm bore, 115 mm stroke, PT1/4 port thread, the built-in magnet sensor option, and the basic mounting configuration. 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 SC50X115S FAQ
At the standard operating pressure of 0.5 MPa, the 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.
Yes. The -S suffix in the model code SC50X115S indicates a built-in magnet on the piston. This allows you to clamp AirTAC CMSG, DMSG, or EMSG sensors directly onto the tie-rod barrel to detect piston position without additional brackets.
