About the Airtac SC50 Standard Cylinder SC50X1540STC
The SC50X1540STC is a long-stroke, non-standard double-acting pneumatic cylinder delivering 982 N of push force at 0.5 MPa (1767 N at the 0.9 MPa max operating pressure). Its 50 mm bore and 20 mm diameter piston rod are engineered for linear applications requiring an extended 1540 mm reach, making it a specialized solution for large-scale material handling or process automation.
This model features a built-in magnet (suffix S) for direct mounting of CMSG/DMSG/EMSG sensors, and a centre trunnion mount (suffix TC) supplied with the TCM1 bracket (F-SC50TC) to allow the cylinder to pivot during operation. The adjustable air cushion at each end, with a 21 mm cushion length, decelerates the piston smoothly, protecting the end caps from impact at high speeds within the 30-800 mm/s range.

Where the Airtac SC50 Standard Cylinder SC50X1540STC Is Used
Long-Reach Sorting Gates
The 1540 mm stroke and pivoting trunnion mount allow this cylinder to actuate large diverter gates on wide conveyor systems, sorting heavy parcels or pallets with 1767 N of force.
Automated Welding Fixtures
Ideal for clamping large fabrications, the long stroke reaches across wide jigs. The built-in magnet provides end-of-stroke confirmation to the welding controller for cycle start.
Grain Silo Slide Gates
Operates heavy slide gates at the base of large storage silos. The centre trunnion mount accommodates structural misalignment, while the 982 N force at 0.5 MPa handles sticky material buildup.
Is the Airtac SC50 Standard Cylinder SC50X1540STC the Right Cylinder?
For applications needing more force, stepping up to the 63 mm bore provides 1559 N at 0.5 MPa. If a shorter, standard stroke is acceptable, the SC50 series offers standard strokes up to 1200 mm. Given the 1540 mm stroke, external guide rails or a guided cylinder are strongly recommended to protect the 20 mm rod from bending under side loads or its own extended weight.
When replacing this cylinder, match five key points: 50 mm bore, 1540 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 direct dimensional and functional swap.
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 SC50X1540STC 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. The theoretical maximum at 1.0 MPa is 200 kgf.
No, 1540 mm exceeds the 1200 mm maximum standard stroke for a 50 mm bore, making this a non-standard, made-to-order item. It is mounted via a centre trunnion (TC), which ships with the TCM1 bracket, and includes a built-in magnet for barrel-mounted sensors.
