About the Airtac SC100 Standard Cylinder SC100X370STC
The AirTAC SC100X370STC is a double-acting single-rod tie-rod cylinder delivering 3927 N push force at 0.5 MPa (7068 N at 0.9 MPa). With a 100 mm bore, 25 mm piston rod and a 370 mm stroke, it suits medium-to-heavy linear actuation where the load must pivot during motion.
This model includes a built-in magnet (-S suffix) for direct mounting of CMSG/DMSG/EMSG reed or solid-state sensors on the barrel, and the TC centre trunnion mount (supplied with TCM1 bracket, order code F-SC100TC) for pivoting actuation. The adjustable air cushion (29 mm) decelerates the piston at end of stroke, protecting the end caps from impact at speeds up to 800 mm/s.

Where the Airtac SC100 Standard Cylinder SC100X370STC Is Used
Conveyor Diverter Gates
Pivoting diverter arms on packaging lines use the trunnion mount to swing product between lanes, with magnetic sensors confirming gate position at each stroke end.
Clamp & Weld Fixtures
Heavy part clamping in robotic welding cells uses the 3927 N force at 0.5 MPa to hold steel fabrications, while the trunnion allows the cylinder body to pivot as the clamp arm cycles.
Bin Tipper Actuation
Drives the tilt mechanism on industrial bin tippers, where the centre trunnion mount absorbs the angular change as the bin rotates to dump bulk material.
Is the Airtac SC100 Standard Cylinder SC100X370STC the Right Cylinder?
Choose the SC100 bore when your application needs around 3927 N at 0.5 MPa. If the load is lighter, stepping down to an SC80 bore (2513 N at 0.5 MPa) can reduce air consumption and physical size. For higher force, the SC125 bore provides 6136 N at the same pressure.
At 370 mm stroke, the 25 mm rod is long enough that side loads or off-centre mounting can cause rod bending and premature bearing wear. Use an external linear guide or a guided cylinder assembly when the load is not perfectly aligned with the rod axis. For replacement, match five points: 100 mm bore, 370 mm stroke, PT port thread, TC centre trunnion mount, and the -S magnet for sensor compatibility.
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 SC100X370STC FAQ
At 0.5 MPa the push force is 3927 N and pull force is 3681 N. At 0.7 MPa push reaches 5497 N, and at the maximum operating pressure of 0.9 MPa the push force is 7068 N. The theoretical maximum at 1.0 MPa is 801 kgf.
This model comes with the TC centre trunnion mount and TCM1 bracket (F-SC100TC). It is a direct replacement only for an AirTAC SC100 tie-rod cylinder of the same 370 mm stroke, PT ports, and -S magnet. If your original cylinder used a foot mount (LB) or flange (FA/FB), you must transfer the old mounting accessories or order the correct suffix variant.
