About the Airtac SC50 Standard Cylinder SC50X1400TC
The AirTAC SC50X1400TC 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 maximum operating pressure of 0.9 MPa. With a 50 mm bore, 20 mm piston rod, and a long 1400 mm stroke, this model is built for linear applications requiring extended reach. The body length A is 150 mm, giving a total extended length of approximately 1550 mm.
This specific code specifies a centre trunnion (TC) mount, supplied with the TCM1 bracket (F-SC50TC), allowing the cylinder to pivot during operation for swinging or articulating loads. The 1400 mm stroke exceeds the standard maximum of 1200 mm for the 50 mm bore, making this a non-standard, made-to-order configuration. Ports are PT1/4 with an M16x1.5 rod thread, and the adjustable air cushion (21 mm) decelerates the piston at the end of stroke to reduce impact.

Where the Airtac SC50 Standard Cylinder SC50X1400TC Is Used
Long-Reach Part Transfer
The 1400 mm stroke is ideal for transferring parts between distant conveyors or workstations in automated assembly lines where a pivoting motion is required.
Material Pusher on Gantry
Mounted on a trunnion, this cylinder can push or pull materials off a moving gantry system, with the long stroke covering a wide work envelope.
Bin Tipping Mechanism
The centre trunnion mount allows the cylinder to pivot a large bin or hopper through a full arc, using the extended stroke for a complete dump cycle.
Is the Airtac SC50 Standard Cylinder SC50X1400TC the Right Cylinder?
For applications needing less force, stepping down to the 40 mm bore provides 628 N of push at 0.5 MPa. For higher force requirements, the 63 mm bore offers 1559 N at the same pressure. The 1400 mm stroke requires careful management of side loads; long, unsupported piston rods are susceptible to bending under radial forces. An external guide or a self-guided cylinder is strongly recommended to protect the rod bearing and seals.
To ensure a direct replacement, match five key specifications: 50 mm bore, 1400 mm stroke, PT1/4 port thread, the TC centre trunnion mounting style, and the absence of a built-in magnet. This cylinder is not dimensionally interchangeable with ISO 15552 profiles, as the SC tie-rod design is shorter.
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 SC50X1400TC 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 increases to 1767 N. The theoretical maximum force at 1.0 MPa is 200 kgf.
Yes, it is highly recommended. A 20 mm diameter rod extending 1400 mm is vulnerable to bending under side loads. An external guide rail or rod support prevents damage to the rod bearing and ensures reliable, long-term operation.
