About the Airtac SC50 Standard Cylinder SC50X1050STC
The SC50X1050STC is a double-acting tie-rod cylinder delivering 982 N of push force at 0.5 MPa (1767 N at 0.9 MPa), built around a 20 mm diameter piston rod and a 150 mm body length A. With a 1050 mm stroke, it provides an extended reach within the standard stroke limit for 50 mm bore SC cylinders, making it a practical choice for long-transfer material handling tasks.
This model includes a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors, and ships with the TC centre trunnion mount plus the TCM1 bracket (F-SC50TC) for pivoting installation. The adjustable air cushion at each end decelerates the piston over 21 mm to soften end-of-stroke impact, protecting the cylinder and the machine structure during high-speed operation.

Where the Airtac SC50 Standard Cylinder SC50X1050STC Is Used
Long-Reach Part Transfer
The 1050 mm stroke moves components between distant conveyor stations. The centre trunnion mount allows the cylinder to pivot, accommodating slight misalignment in the transfer path.
Automated Assembly Pusher
Delivers 982 N at 0.5 MPa to push heavy assemblies along a fixture. The built-in magnet enables end-of-stroke sensing with CMSG sensors for cycle confirmation.
Palletising Gate Actuator
Operates a tall diverter gate in packaging lines. The 21 mm adjustable cushion absorbs the energy of the moving gate, reducing noise and mechanical shock at the end of travel.
Is the Airtac SC50 Standard Cylinder SC50X1050STC the Right Cylinder?
Choose the SC50 bore when your application needs roughly 1000 N of force at standard plant pressure; if you require more force, step up to the SC63 which provides 1559 N push at 0.5 MPa. For lighter, more compact installations, the SC40 delivers 628 N. This 1050 mm stroke is within the 1200 mm maximum standard stroke for bore 50, so no special order lead time applies.
For strokes of this length, the 20 mm rod can experience bending under side load. Always guide the load externally with a rail or rod guide, or consider a guided cylinder if off-axis forces are present. When replacing an existing unit, match five points: 50 mm bore, 1050 mm stroke, PT port thread, TC centre trunnion mounting, and the -S magnet for sensor compatibility.
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 SC50X1050STC FAQ
At 0.5 MPa air pressure, this 50 mm bore cylinder produces 982 N extending and 825 N retracting. At the maximum operating pressure of 0.9 MPa, the push force rises to 1767 N. The theoretical maximum at 1.0 MPa is 200 kgf.
Yes, the -S suffix indicates a built-in magnet, so you can clamp CMSG reed or DMSG/EMSG solid-state sensors directly onto the barrel for position feedback. The TC code means it comes with a centre trunnion and TCM1 bracket (F-SC50TC) for a pivoting mount; the cylinder body swings around the trunnion axis during operation.
