About the Airtac SC50 Standard Cylinder SC50X110STC
The SC50X110STC is a double-acting tie-rod cylinder delivering 982 N of push force at 0.5 MPa and up to 1767 N at 0.9 MPa. Its 110 mm stroke is ideal for medium-reach clamping, pressing, and sorting tasks where a compact body length of 150 mm (A dimension) plus stroke keeps the footprint manageable.
This model comes factory-equipped with a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors, and a centre trunnion mount (TC) with the TCM1 bracket, allowing the cylinder to pivot freely under swinging loads. The 20 mm diameter rod and M16x1.5 knuckle thread provide robust guidance for linear motion.

Where the Airtac SC50 Standard Cylinder SC50X110STC Is Used
Part Sorting & Diverting
The 110 mm stroke and trunnion mount allow the cylinder to pivot and push items off a conveyor line, with magnetic sensors confirming each cycle.
Automated Clamping
Delivers 1767 N of force at 0.9 MPa for holding workpieces in CNC fixtures, with the adjustable air cushion softening the clamp impact.
Linkage Actuation
The centre trunnion mount absorbs the arc motion of linkages, making this cylinder suitable for opening and closing safety gates or hopper doors.
Is the Airtac SC50 Standard Cylinder SC50X110STC the Right Cylinder?
For higher force requirements, consider stepping up to the SC63 bore, which offers 1559 N at 0.5 MPa. If a lower force and lighter weight is preferred, the SC40 bore provides 628 N. The 110 mm stroke is well within the 1200 mm maximum standard stroke for the 50 mm bore.
To ensure a correct replacement, match five key points: bore (50 mm), stroke (110 mm), PT port thread, centre trunnion mounting (TC with F-SC50TC bracket), and the built-in magnet (-S) for sensor compatibility. For strokes over 300 mm, always consider an external guide to protect the rod from bending under side loads.
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 SC50X110STC FAQ
At the standard 0.5 MPa operating pressure, 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 increases to 1767 N.
No. The SC series is a tie-rod cylinder and is physically shorter than an ISO 15552 profile cylinder, so it is not dimensionally interchangeable. It directly replaces another AirTAC SC50 cylinder with the same stroke, PT ports, TC mount, and magnet.
