About the Airtac SC100 Standard Cylinder SC100X70STC
The AirTAC SC100X70STC is a double-acting tie-rod cylinder delivering 3927 N of push force at 0.5 MPa (up to 7068 N at 0.9 MPa). Its 70 mm stroke is well within the 1500 mm maximum for the 100 mm bore, making this a compact yet powerful unit for short-throw actuation.
This configuration includes a built-in magnet (-S suffix) for direct mounting of CMSG/DMSG/EMSG sensors, and a centre trunnion mount (-TC suffix) with the TCM1 bracket (F-SC100TC) for pivoting applications. The 25 mm diameter rod and PT1/2 ports handle high flow, while the 29 mm adjustable air cushion decelerates the piston smoothly at end of stroke.

Where the Airtac SC100 Standard Cylinder SC100X70STC Is Used
Conveyor Diverter Gates
The 3927 N push force at 0.5 MPa easily actuates heavy diverter gates on wide conveyor lines, while the trunnion mount allows the cylinder to pivot as the gate swings through its arc.
Clamping Fixtures
Delivers up to 7068 N of clamping force at 0.9 MPa for securing large weldments or castings. The magnetic piston enables end-of-stroke confirmation via barrel-mounted sensors.
Press Feed Mechanisms
The short 70 mm stroke provides a rapid, powerful push to index material into a stamping press. The centre trunnion allows the cylinder body to self-align during the feed cycle.
Is the Airtac SC100 Standard Cylinder SC100X70STC the Right Cylinder?
Select the SC100 when your load requires roughly 4000 N at standard plant pressure. If your force need is closer to 2500 N, stepping down to an 80 mm bore (2513 N at 0.5 MPa) can reduce air consumption and physical size. For strokes over 300 mm on this bore, consider an external guide to protect the 25 mm rod from bending under side load.
For replacement, match five points: 100 mm bore, 70 mm stroke, PT port thread, centre trunnion (TC) mounting with the TCM1 bracket, and the built-in magnet (-S) for sensor compatibility. This ensures a drop-in fit for another AirTAC SC series 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 SC100X70STC FAQ
At 0.5 MPa (approx. 73 psi), 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. The theoretical maximum at 1.0 MPa is 801 kgf.
No. The SC100X70STC is a double-acting cylinder and will not hold position if pressure is exhausted or the directional valve is centered. The piston can drift or drop. For load holding without live pressure, you must add a pilot-operated check valve or an external mechanical rod lock.
