About the Airtac SC50 Standard Cylinder SC50X130STC
The SC50X130STC is a double-acting pneumatic cylinder delivering a push force of 982 N at 0.5 MPa and up to 1767 N at 0.9 MPa operating pressure. With a 50 mm bore and 130 mm stroke, this tie-rod actuator uses a 20 mm diameter piston rod with an M16x1.5 male thread for tool attachment.
This configuration includes a built-in magnet (S suffix) for direct mounting of CMSG/DMSG/EMSG sensors, enabling precise end-of-stroke detection. The TC suffix denotes a centre trunnion mount, supplied with the TCM1 bracket (F-SC50TC), allowing the cylinder body to pivot during operation. It features adjustable pneumatic cushioning and PT1/4 ports.

Where the Airtac SC50 Standard Cylinder SC50X130STC Is Used
Part Diverter Gates
The centre trunnion mount allows the cylinder to swing, making it ideal for actuating diverter gates on conveyor lines where the path of motion is an arc rather than a straight line.
Clamping with Position Feedback
With the built-in magnet, this cylinder is well-suited for automated clamping fixtures. Magnetic sensors confirm the clamp is fully engaged before a machining cycle starts, preventing crashes.
Packaging Machinery Linkages
Delivers 982 N of push force for folding cartons or advancing product trays. The pivoting TC mount absorbs minor misalignments in linkage mechanisms, reducing rod bearing wear.
Is the Airtac SC50 Standard Cylinder SC50X130STC the Right Cylinder?
Select the SC50X130STC for applications needing a pivoting mount and sensor feedback. If your force requirement is lower, consider stepping down to the 40 mm bore (628 N at 0.5 MPa). For higher force, the 63 mm bore provides 1559 N at the same pressure. When replacing an existing cylinder, match the 50 mm bore, 130 mm stroke, PT1/4 port thread, TC centre trunnion mount, and the integrated magnet sensor option to ensure direct interchangeability with another AirTAC SC unit.
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 SC50X130STC FAQ
At the standard operating pressure of 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.
To guarantee a direct drop-in replacement, match the 50 mm bore, 130 mm stroke, PT1/4 port thread, TC centre trunnion mount, and the -S magnet option. The mounting kit F-SC50TC includes the trunnion body and TCM1 bracket.
