About the Airtac SC100 Standard Cylinder SC100X1250TC
The AirTAC SC100X1250TC is a double-acting tie-rod cylinder delivering a substantial 3927 N push force at 0.5 MPa (7068 N at 0.9 MPa). Its 100 mm bore and 1250 mm stroke suit long linear movements in heavy industrial automation, with a 25 mm diameter piston rod providing excellent rigidity for the force class.
This model includes a centre trunnion (TC) mount, supplied with the TCM1 bracket (F-SC100TC), allowing the cylinder to pivot during operation. The standard PT1/2 ports and adjustable air cushion (29 mm length) ensure smooth deceleration at stroke ends, while the TPU seals offer reliable performance from -20 to +70 °C.

Where the Airtac SC100 Standard Cylinder SC100X1250TC Is Used
Long-Stroke Material Transfer
The 1250 mm stroke moves heavy pallets or components across wide conveyor gaps, with the trunnion mount absorbing misalignment in pivoting transfer arms.
Heavy Press Feed Systems
Delivers 3927 N at 0.5 MPa to push large sheet metal blanks into stamping presses, where the adjustable cushion protects tooling from impact at cycle end.
Automated Diverter Gates
Pivots large diverter chutes in bulk handling lines using the TC mount, directing product flow with the cylinder's high force overcoming material weight and friction.
Is the Airtac SC100 Standard Cylinder SC100X1250TC the Right Cylinder?
Select the SC100 for applications needing up to 3927 N at 0.5 MPa; step down to the SC80 bore (2513 N at 0.5 MPa) if force requirements are lower, or up to the SC125 (6136 N at 0.5 MPa) for heavier loads. For this 1250 mm stroke, side-load management is critical—an unsupported 25 mm rod at full extension is vulnerable to bending under lateral force. Always use an external guide rail or a guided cylinder assembly to protect the rod bearings and ensure linear motion accuracy.
When replacing an existing cylinder, match five points exactly: 100 mm bore, 1250 mm stroke, PT1/2 port thread, centre trunnion (TC) mounting with F-SC100TC bracket, and no built-in magnet. This ensures dimensional and functional interchangeability with another AirTAC SC tie-rod cylinder.

- ✓ 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 SC100X1250TC FAQ
At 0.5 MPa, the push force is 3927 N and pull force is 3681 N. At the maximum operating pressure of 0.9 MPa, push force reaches 7068 N. The theoretical maximum at 1.0 MPa is 801 kgf.
For strokes of 300 mm or more, never subject the extended rod to side (radial) loads without external guidance. Install a linear guide rail or rod support to carry the lateral force, protecting the rod bearing and piston seals from premature wear and ensuring straight-line motion.
