About the Airtac SC100 Standard Cylinder SC100X300STC
This SC100X300STC double-acting cylinder delivers a substantial 3927 N of push force at 0.5 MPa, scaling up to 7068 N at the maximum operating pressure of 0.9 MPa. The 300 mm stroke is well within the standard range for the 100 mm bore, making it a readily available configuration for medium-travel linear applications.
The built-in magnet, denoted by the 'S' in the ordering code, allows for direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors on the tie-rod barrel for precise, non-contact position sensing. It comes fitted with a TC centre trunnion bracket (F-SC100TC), enabling the cylinder body to pivot and absorb misalignment in swinging load applications.

Where the Airtac SC100 Standard Cylinder SC100X300STC Is Used
Conveyor Diverter Gates
The 3927 N push force at standard line pressure is ideal for actuating heavy diverter gates on wide conveyor systems, reliably sorting pallets or large packages.
Heavy-Duty Clamping
Provides controlled, high-force clamping for large weldments or heavy fabrications in a jig, with the trunnion mount allowing the cylinder to self-align during the stroke.
Pivoting Press Feed
The centre trunnion mount allows the cylinder body to swing, making it perfect for feeding blanks into a stamping press where the actuator must pivot out of the way on the return stroke.
Is the Airtac SC100 Standard Cylinder SC100X300STC the Right Cylinder?
Selecting the SC100X300STC provides a robust force output suitable for pressing, clamping, and material handling tasks. If your application requires a lighter, more compact actuator, stepping down to the 80 mm bore reduces the push force to 2513 N at 0.5 MPa. For strokes of 300 mm or more, always evaluate the potential for side loading on the 25 mm diameter piston rod. An external guide rail or rod-alignment coupler is strongly recommended to prevent rod bearing wear and ensure long service life when the load is not perfectly axial.

- ✓ 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 SC100X300STC FAQ
At 0.6 MPa (6 bar), the theoretical push force on the piston is 4712 N, and the pull force on the annulus side is 4417 N. These values are calculated from the 100 mm bore and 25 mm rod diameter.
No. The AirTAC SC series is a tie-rod cylinder with a shorter overall body length than a comparable ISO 15552 profile cylinder. For a successful replacement, match the bore, stroke, PT port thread, TC centre trunnion mount, and the -S magnet option exactly.
