About the Airtac SC50 Standard Cylinder SC50X110CB
The SC50X110CB is a 50 mm bore AirTAC SC series double-acting tie-rod cylinder with a 110 mm stroke and a rear double clevis (CB) mount. It produces 982 N of push force at 0.5 MPa and up to 1767 N at the maximum operating pressure of 0.9 MPa, making it a robust workhorse for medium-force industrial tasks.
The cylinder uses a 20 mm diameter piston rod with an M16x1.5 male thread and PT1/4 port connections. Its adjustable air cushion (21 mm length) decelerates the piston smoothly at end-of-stroke, reducing impact and noise. The CB mount (part F-SC50CB) provides a pivoting fork connection at the rear cap, ideal for applications where the cylinder body needs to articulate.

Where the Airtac SC50 Standard Cylinder SC50X110CB Is Used
Linkage Actuation
The rear double clevis mount allows the cylinder body to pivot, making it suitable for actuating linkages on agricultural equipment like planter row units or chute diverters.
Part Diverter Gates
Delivers a firm 982 N push at standard shop air to reliably swing diverter gates on conveyor systems, sorting packages or bulk materials by size or destination.
Clamping & Fixturing
Used in welding jigs and assembly fixtures where the cylinder body must pivot to engage a clamp arm. The adjustable cushion prevents hammering at full extension, protecting the fixture.
Is the Airtac SC50 Standard Cylinder SC50X110CB the Right Cylinder?
For a step up in force, the 63 mm bore SC63 series delivers 1559 N push at 0.5 MPa, while stepping down to a 40 mm bore provides 628 N. Always match replacement cylinders on five points: 50 mm bore, 110 mm stroke, PT port thread, rear double clevis (CB) mounting, and the absence of a built-in magnet.
At 110 mm stroke, the SC50's 20 mm rod is well-supported for axial loads, but avoid unguided side loads which can bend the rod or score the bearing. For applications with lateral forces, pair the cylinder with an external linear guide or switch to a guided cylinder unit.
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 SC50X110CB FAQ
At 0.5 MPa, the cylinder pushes with 982 N and pulls with 825 N. At 0.7 MPa, push force rises to 1374 N, and at the maximum operating pressure of 0.9 MPa, it reaches 1767 N. The theoretical maximum at 1.0 MPa is 200 kgf.
Yes, provided the replacement matches the 50 mm bore, 110 mm stroke, PT1/4 ports, and rear double clevis (CB) mounting style. The SC series is a direct replacement for previous AirTAC SC tie-rod cylinders with the same specifications, but it is not dimensionally interchangeable with ISO 15552 profile cylinders.
