About the Airtac SC50 Standard Cylinder SC50X1500TC
The AirTAC SC50X1500TC is a double-acting tie-rod cylinder delivering 982 N of push force at 0.5 MPa (1767 N at the maximum operating pressure of 0.9 MPa). Its 20 mm diameter piston rod and 150 mm body length A provide a robust linear drive for long-stroke applications, with the extended length reaching approximately 1650 mm.
This model features a centre trunnion (TC) mount, supplied with the TCM1 bracket (F-SC50TC), allowing the cylinder to pivot as it operates. The 1500 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, and the adjustable air cushion (21 mm) decelerates the piston at end-of-stroke to reduce impact.

Where the Airtac SC50 Standard Cylinder SC50X1500TC Is Used
Long-Reach Part Transfer
The 1500 mm stroke moves components across wide gaps in automated assembly lines, with the trunnion mount absorbing any slight misalignment during the transfer motion.
Pivoting Clamp Actuation
Ideal for a large welding fixture where the cylinder body must swing. The TC mount allows the entire cylinder to pivot, applying 1767 N of clamping force at 0.9 MPa.
Bin Diverter Gate
Operates a tall diverter chute in a material handling system. The long stroke provides the necessary travel, while the trunnion mount handles the arcing motion of the gate linkage.
Is the Airtac SC50 Standard Cylinder SC50X1500TC the Right Cylinder?
Choose the SC50 when the 40 mm bore's 628 N push force at 0.5 MPa is insufficient, but the 63 mm bore's 1559 N is more than needed. For this 1500 mm stroke, the long, unsupported 20 mm rod is susceptible to bending under side loads; an external linear guide or a guided cylinder is strongly recommended to protect the rod bearing and seals.
To replace an existing unit, match five points: 50 mm bore, 1500 mm stroke, PT1/4 port thread, centre trunnion (TC) mounting with the TCM1 bracket, and the absence of a magnet. This SC is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders.
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 SC50X1500TC FAQ
At the standard 0.5 MPa operating pressure, the cylinder provides 982 N pushing and 825 N pulling force. 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.
It is not recommended. The 20 mm diameter rod on a 1500 mm stroke is highly vulnerable to side-load bending, which will cause premature rod bearing wear and seal failure. Always use an external guide rail or a guided cylinder for any significant side load.
