About the Airtac SC50 Standard Cylinder SC50X1100TC
The AirTAC SC50X1100TC is a double-acting pneumatic cylinder with a 50 mm bore and an 1100 mm stroke, equipped with a centre trunnion mount for pivoting applications. At the standard 0.5 MPa operating pressure, it provides 982 N of push force and 825 N of pull force, making it suitable for medium-load linear actuation.
This model features a 20 mm diameter piston rod with M16x1.5 male threads and PT1/4 ports. The 1100 mm stroke is within the maximum standard stroke of 1200 mm for the 50 mm bore, and the cylinder body length (dimension A) is 150 mm. The adjustable air cushion at both ends decelerates the piston to reduce end-of-stroke impact.

Where the Airtac SC50 Standard Cylinder SC50X1100TC Is Used
Conveyor Diverter Gates
The 1100 mm stroke and pivoting trunnion mount suit long-reach diverter arms on packaging lines, where the 982 N force reliably redirects products between lanes.
Material Lift Tables
Provides the extended vertical travel needed for scissor-lift mechanisms in assembly stations, with the centre trunnion allowing the cylinder body to pivot as the lift cycles.
Agricultural Equipment Actuation
Operates chute controls or hopper doors on farming machinery, delivering consistent force over a long stroke in dusty environments with filtered compressed air.
Is the Airtac SC50 Standard Cylinder SC50X1100TC the Right Cylinder?
Select the SC50 when your application requires a push force around 982 N at 0.5 MPa. For higher force, step up to the SC63 bore which delivers 1559 N push at the same pressure; for a lighter, more compact solution, the SC40 bore provides 628 N push. This cylinder's 1100 mm stroke requires careful management of side loads to prevent rod bending—consider an external linear guide or a guided cylinder for unsupported loads.
To ensure a correct replacement, match five key specifications: 50 mm bore, 1100 mm stroke, PT1/4 port thread, the TC centre trunnion mounting (includes F-SC50TC and TCM1 bracket), and the absence of a built-in magnet. This 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 SC50X1100TC FAQ
At 0.5 MPa (5 bar), the SC50X1100TC produces 982 N of push force and 825 N of pull force. At the maximum operating pressure of 0.9 MPa, push force increases to 1767 N. The theoretical maximum force at 1.0 MPa is 200 kgf.
No. The SC50X1100TC is a double-acting cylinder and does not hold its position when air pressure is removed or the directional valve is centred. The piston will drift or drop under load. For load holding without live pressure, you must add a pilot-operated check valve or an external mechanical rod brake.
