About the Airtac SCT80~100 Multi-Position Tandem Cylinder SCT100X60X65
This AirTAC SCT100X60X65 multi-position cylinder provides four fixed rod positions—0 mm, 60 mm, 65 mm, and the combined 125 mm total travel—by pressurising its two tandem piston sections independently or together. With a 100 mm bore and a robust 25 mm diameter rod, each section generates 3927 N of push force at 0.5 MPa, rising to 7068 N at the maximum operating pressure of 0.9 MPa.
Engineered as a durable tie-rod cylinder, the body length A(SCT) is 308 mm and it features a 29 mm adjustable air cushion for smooth end-of-stroke deceleration. The standard PT1/2 port threads and M20x1.5 rod end thread ensure straightforward pneumatic integration. This configuration is ideal for heavy-duty sorting or staging tasks requiring two distinct extended positions beyond the home stop.

| Model | Airtac SCT80~100 Multi-Position Tandem Cylinder SCT100X60X65 |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø100 mm |
| Stroke 1 / Stroke 2 | 60 / 65 mm |
| Total travel | 125 mm |
| Stop positions | 4 positions |
| Acting type | Double acting (tandem, multi-position) |
| Port size | PT1/2 |
| Rod thread | M20×1.5 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 30 – 800 mm/s |
| Cushion | Adjustable, 29 mm |
| Max stroke / section | Up to 500 mm standard |
Specifications follow the official AirTAC SCT (multi-position) datasheet. SCT is available in bores 32–100; each of the two sections has a 500 mm max standard stroke (800 mm max). Confirm against the product label before installation. Thread options: PT (standard) / G.
Stop Positions (4)
| Position | Rod extension |
|---|---|
| P0 (retracted) | 0 mm |
| P1 (section 1) | 60 mm |
| P2 (section 2) | 65 mm |
| P3 (both extended) | 125 mm |
Positions are set by pressurising section 1, section 2, or both. With equal strokes you get 3 distinct positions; with unequal strokes you get 4.
Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | — |
| Max (@1.0 MPa) | 801 kgf | |
Force is per actuated piston section (single-piston, same as the SC bore): push uses the full bore area, pull subtracts the rod area. Size with a safety margin.

Where the Airtac SCT80~100 Multi-Position Tandem Cylinder SCT100X60X65 Is Used
Heavy Part Diverting
Uses the 60 mm and 65 mm extensions to route large components down three separate conveyor lanes from a single infeed point.
Two-Stage Clamping
Applies an initial clamp at the 60 mm position and a final high-force press at the full 125 mm extension for assembly processes.
Multi-Depth Stopping
Provides precise, repeatable stops for a pallet or workpiece at two different depths within a machining or welding fixture.
Is the Airtac SCT80~100 Multi-Position Tandem Cylinder SCT100X60X65 the Right Cylinder?
Select this SCT100X60X65 when a single actuator must reliably index a heavy load to two separate extended positions, eliminating the complexity and plumbing of two individual cylinders with external hard stops. The 60 mm and 65 mm strokes create a compact 5 mm offset between the intermediate stops, suitable for fine part differentiation. If higher force is not required, stepping down to an 80 mm bore reduces the per-section push force to 2513 N at 0.5 MPa, potentially lowering air consumption. A direct replacement must match the 100 mm bore, both 60 mm and 65 mm strokes, PT port thread, and basic mounting configuration.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 60 + 65 mm suit your layout?
- ✓ Required force at your working pressure
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Plumb the two sections to the correct valves for each stop.
- check Adjust end cushion screws for smooth stops.
- check Use SCT mounting accessory (FA / FB / CA / CB / LB).
- check Installation by qualified personnel per AirTAC docs.
Airtac SCT80~100 Multi-Position Tandem Cylinder SCT100X60X65 FAQ
It provides four discrete, fixed positions: fully retracted (0 mm), first section extended (60 mm), second section extended (65 mm), and both sections extended for the total travel (125 mm).
Yes, it is designed to do exactly that. It replaces two independent cylinders and their mounting hardware with a single, compact tandem unit, providing two distinct extended stops from one assembly. The replacement must have the same 100 mm bore, 60 mm and 65 mm strokes, and PT ports.
