About the Airtac SC50 Standard Cylinder SC50X1450SCB
The AirTAC SC50X1450SCB is a double-acting single-rod pneumatic cylinder with a 50 mm bore and an extended 1450 mm non-standard stroke, delivering 982 N of push force at 0.5 MPa and up to 1767 N at the maximum operating pressure of 0.9 MPa. This model is factory-configured with a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors and a rear double clevis (CB) mount, part F-SC50CB, that allows the cylinder body to pivot during operation.
With a 20 mm diameter piston rod and M16x1.5 rod thread, the unit features adjustable pneumatic cushioning (21 mm cushion length) at both ends to decelerate the piston smoothly. The body length A is 150 mm, resulting in a total extended length of approximately 1600 mm. As a non-standard stroke exceeding the 1200 mm maximum for bore 50, this is a made-to-order item. Ports are PT1/4 with the default TPU seals rated for -20 to +70 °C.

Where the Airtac SC50 Standard Cylinder SC50X1450SCB Is Used
Long-Reach Material Transfer
The 1450 mm stroke pushes or pulls lightweight components across wide conveyor gaps or between distant workstations, with the rear clevis mount accommodating the arcing motion of a pivoting transfer arm.
Automated Welding Positioners
Positions welding torches or clamps over a large working envelope. The built-in magnet allows end-of-stroke sensing to confirm tool position, while the clevis mount handles the pivoting action of the positioner arm.
Vertical Gate Actuation
Operates a tall hopper gate or diverter chute in agricultural or bulk-handling equipment. The double clevis mounting provides a stable, self-aligning pivot point for the cylinder as the gate swings open or closed.
Is the Airtac SC50 Standard Cylinder SC50X1450SCB the Right Cylinder?
For applications requiring slightly less force, the 40 mm bore SC series provides 628 N at 0.5 MPa, while stepping up to the 63 mm bore offers 1559 N at the same pressure. This 1450 mm stroke model demands careful attention to side-load management: the long, unsupported 20 mm rod is susceptible to bending under lateral forces, so an external linear guide or a self-guided cylinder should be used to protect the rod bearing and seals.
When replacing this unit, match five key specifications: 50 mm bore, 1450 mm stroke, PT1/4 port thread, the rear double clevis (CB) mounting accessory, and the built-in magnet (-S) for sensor compatibility. This ensures a direct dimensional and functional drop-in for another AirTAC SC tie-rod cylinder.
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 SC50X1450SCB FAQ
At the standard 0.5 MPa operating pressure, the cylinder produces 982 N of push force and 825 N of pull force. At the maximum operating pressure of 0.9 MPa, the push force increases to 1767 N. The theoretical maximum force at 1.0 MPa is 200 kgf.
No, 1450 mm exceeds the 1200 mm maximum standard stroke for a 50 mm bore SC cylinder, making this a non-standard, made-to-order item. For such a long stroke, you must never apply direct side loads to the rod. Always use an external linear guide or couple the rod to a guided carriage to prevent bending and premature seal failure.
