About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT40X330X270
The SCT40X330X270 is a double-acting multi-position cylinder that delivers four distinct rod positions: 0 mm, 270 mm, 330 mm, and the full combined travel of 600 mm. Each piston section independently generates 628 N of push force at 0.5 MPa, offering precise control for two-stage movements without needing complex external stops.
The 16 mm diameter rod and 21 mm adjustable air cushion at each end ensure smooth deceleration across the stroke ranges. With a body length A of 235 mm, this tie-rod design fits compactly into machinery where a single cylinder must handle two different extension depths.
Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT40X330X270 Technical Specifications
| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT40X330X270 |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø40 mm |
| Stroke 1 / Stroke 2 | 330 / 270 mm |
| Total travel | 600 mm |
| Stop positions | 4 positions |
| Acting type | Double acting (tandem, multi-position) |
| Port size | PT1/4 |
| Rod thread | M12×1.25 |
| 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, 21 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) | 330 mm |
| P2 (section 2) | 270 mm |
| P3 (both extended) | 600 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 (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 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 SCT32-63 Multi-Position Tandem Air Cylinder SCT40X330X270 Is Used
Two-Stage Sorting Gate
Actuates a diverter gate to two different open positions, routing packages based on size with the 270 mm and 330 mm stroke stops.
Dual-Depth Clamping
Applies an initial low-force clamp at 270 mm travel, then a secondary full-pressure clamp at 330 mm for delicate assembly processes.
Sequential Part Feeding
Advances a workpiece in two controlled steps, first by 270 mm for inspection, then a further 60 mm to a processing station at the 330 mm position.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT40X330X270 the Right Cylinder?
Choose the SCT40X330X270 when your application requires two distinct extension lengths from one compact unit, eliminating the alignment and plumbing complexity of two separate cylinders. If higher force is needed, stepping up to the 50 mm bore provides 982 N of push per section at the same pressure. For a drop-in replacement, match the 40 mm bore, both 330 mm and 270 mm strokes, PT port thread, and basic mounting. Given the 330 mm section stroke, ensure the rod is adequately guided if significant side loads are present to prevent bending.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 330 + 270 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 SCT32-63 Multi-Position Tandem Air Cylinder SCT40X330X270 FAQ
This tandem cylinder provides four discrete stop positions: fully retracted (0 mm), the first section extended (270 mm), the second section extended (330 mm), and both sections extended for the total travel (600 mm).
Yes, the SCT40X330X270 replaces two 40 mm bore cylinders with 270 mm and 330 mm strokes, simplifying mounting and air plumbing. Ensure the replacement matches the PT port thread and basic mounting configuration.
