About the Airtac SC100 Standard Cylinder SC100X50STC
The SC100X50STC is a double-acting pneumatic cylinder delivering a push force of 3927 N at 0.5 MPa, scaling up to a powerful 7068 N at 0.9 MPa. With a 100 mm bore and a short 50 mm stroke, it is built for compact, high-force clamping, pressing, or ejecting tasks where space is limited.
This model features a built-in magnet for direct mounting of CMSG/DMSG/EMSG sensors and comes equipped with a TC centre trunnion mount (including the TCM1 bracket, order code F-SC100TC). The trunnion allows the cylinder to pivot, accommodating swinging loads. The 25 mm diameter piston rod and 29 mm adjustable air cushion ensure robust, decelerated end-of-stroke performance.

Where the Airtac SC100 Standard Cylinder SC100X50STC Is Used
Heavy-Duty Clamping
Generates up to 7068 N of force at 0.9 MPa for securely holding large workpieces during machining or welding in compact fixtures.
Short-Stroke Ejection
The 50 mm stroke provides a powerful, rapid punch for ejecting parts from dies or molds on high-speed automated lines.
Pivoting Diverter Gate
The TC centre trunnion mount allows the cylinder body to pivot, making it ideal for actuating diverter gates on conveyor systems.
Is the Airtac SC100 Standard Cylinder SC100X50STC the Right Cylinder?
For applications needing more force, stepping up to a 125 mm bore provides 6136 N at 0.5 MPa. If a lower force profile is acceptable, the 80 mm bore offers 2513 N at the same pressure. This 50 mm stroke is standard and well within the 1500 mm maximum for the 100 mm bore.
To ensure a direct replacement, match five key points: the 100 mm bore, 50 mm stroke, PT port thread, TC centre trunnion mounting, and the integrated magnet (-S suffix). This tie-rod cylinder is shorter than an ISO 15552 profile and is not dimensionally interchangeable with that standard.
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 SC100 Standard Cylinder SC100X50STC FAQ
At the standard 0.5 MPa operating pressure, the push force is 3927 N and the pull force is 3681 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 7068 N.
No. The AirTAC SC series is a tie-rod cylinder with a shorter overall body length than an ISO 15552 cylinder. It is a direct replacement only for another AirTAC SC100 cylinder with identical bore, stroke, PT ports, TC mount, and magnet.
