About the Airtac SC50 Standard Cylinder SC50X625STC
The AirTAC SC50X625STC is a double-acting single-rod pneumatic cylinder delivering 982 N of push force at 0.5 MPa and up to 1767 N at the 0.9 MPa maximum operating pressure. With a 50 mm bore, 20 mm rod and a 625 mm stroke, this model is built for medium-force linear tasks where a long reach is essential.
This configuration includes a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors, and a centre trunnion TC mount (supplied with TCM1 bracket, part F-SC50TC) that lets the cylinder pivot during operation. The 625 mm stroke exceeds the standard maximum of 1200 mm for bore 50, making this a non-standard, made-to-order length. Cushioning is adjustable over 21 mm at each end to decelerate the piston smoothly.

Where the Airtac SC50 Standard Cylinder SC50X625STC Is Used
Long-Reach Part Transfer
The 625 mm stroke pushes or pulls components across wide conveyor gaps, and the trunnion mount allows the cylinder body to pivot as the tooling moves.
Clamping & Fixturing
Delivers up to 1767 N of clamping force at 0.9 MPa for holding workpieces in CNC or welding fixtures, with sensor confirmation of the clamped position via the built-in magnet.
Pivoting Actuator Linkage
The centre trunnion mount is ideal for linkages that need the cylinder to swing through an arc, such as bin tippers or diverter gates on material handling lines.
Is the Airtac SC50 Standard Cylinder SC50X625STC the Right Cylinder?
Choose the SC50 when your application needs roughly 1000 N of force at typical shop air; if you need more, stepping up to the SC63 delivers 1559 N push at 0.5 MPa. For this 625 mm stroke, the long unsupported rod is vulnerable to bending under side load—add an external linear guide or use a guided cylinder if the load is not perfectly axial. When replacing an existing unit, match five points: 50 mm bore, 625 mm stroke, PT port thread, centre trunnion (TC) mounting, and the built-in magnet for sensors.
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 SC50X625STC FAQ
At 0.5 MPa it pushes with 982 N and pulls with 825 N. At the maximum operating pressure of 0.9 MPa, push force reaches 1767 N. The theoretical maximum at 1.0 MPa is 200 kgf.
No. The SC50 is a standard double-acting cylinder and will drift or drop if pressure is exhausted. For load holding without live pressure, you must add an external rod lock, brake, or a pilot-operated check valve.
