About the Airtac SC50 Standard Cylinder SC50X1000STC
The AirTAC SC50X1000STC 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 1000 mm stroke is the maximum standard length for the 50 mm bore, making it a go-to linear drive for long-transfer applications where a compact body length is still required.
This model is factory-equipped with a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors, and a centre trunnion mount (TC) supplied with the TCM1 bracket (F-SC50TC). The 20 mm diameter piston rod and 21 mm adjustable air cushion at each end provide smooth deceleration, while the PT1/4 port threads ensure straightforward pneumatic connections.

Where the Airtac SC50 Standard Cylinder SC50X1000STC Is Used
Long-Stroke Material Transfer
Pushes or pulls bins and pallets across a 1-metre span on roller conveyors, using the full 1000 mm stroke and 982 N force at 0.5 MPa.
Automated Welding Fixtures
Positions heavy welding jigs with the centre trunnion mount allowing the cylinder to pivot, while magnetic sensors confirm clamp/unclamp status.
Vertical Lift Gates
Operates a 1-metre vertical panel lift, using the adjustable cushion to soften end-of-stroke impact and the trunnion to handle the pivoting arc.
Is the Airtac SC50 Standard Cylinder SC50X1000STC the Right Cylinder?
Choose the SC50 bore when your application needs around 982 N of force at standard plant pressure; if you require significantly more, step up to the SC63 which provides 1559 N at the same 0.5 MPa. For a 1000 mm stroke, always assess side-loading: the 20 mm rod is robust, but an external guide rail or a guided cylinder is strongly recommended to protect the rod bearing from bending moments during long extensions.
To replace an existing unit, match five points: 50 mm bore, 1000 mm stroke, PT port thread, centre trunnion (TC) mounting with the TCM1 bracket, and the built-in magnet (-S) for sensor compatibility. This ensures a drop-in fit for another AirTAC SC tie-rod cylinder of the same configuration.
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 SC50X1000STC FAQ
At 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 at 1.0 MPa is 200 kgf.
Yes, it is highly recommended. At full extension, a 1000 mm stroke on a 20 mm rod creates a long lever arm. Any side load can bend the rod or damage the bearing. Use an external guide rail or switch to a guided cylinder if side forces are present.
