About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X80X5
The AirTAC SCT63X80X5 tandem cylinder delivers four fixed rod positions—0 mm, 5 mm, 80 mm, and the combined 85 mm—from a single compact assembly. Each 63 mm bore section generates 1559 N of push force at 0.5 MPa, making it a space-saving alternative to mounting two separate actuators for two-depth or sorting tasks.
With a 20 mm diameter rod and PT1/4 ports, this double-acting unit uses adjustable air cushioning (28 mm length) at both ends for smooth deceleration. The tie-rod body has an A(SCT) dimension of 249 mm, and the standard TPU seals suit operating temperatures from -20 to +70 °C.
Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X80X5 Technical Specifications
| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X80X5 |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø63 mm |
| Stroke 1 / Stroke 2 | 80 / 5 mm |
| Total travel | 85 mm |
| Stop positions | 4 positions |
| Acting type | Double acting (tandem, multi-position) |
| Port size | PT1/4 |
| Rod thread | M16×1.5 |
| 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, 28 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) | 80 mm |
| P2 (section 2) | 5 mm |
| P3 (both extended) | 85 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 (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1559 N | 1402 N |
| 0.7 MPa | 2182 N | — |
| Max (@1.0 MPa) | 318 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 SCT63X80X5 Is Used
Two-Depth Pressing
Uses the 5 mm stroke for a light pre-load or detent before applying full force through the 80 mm section, ideal for delicate assembly presses.
Sorting Gate Actuation
The 0, 5, 80, and 85 mm positions divert parts to four distinct lanes on a conveyor, controlled purely by pressurising each tandem section.
Multi-Stop Clamping
Provides a precise 5 mm clearance position for part loading and an 80 mm clamping stroke, eliminating the need for manual setup adjustments.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X80X5 the Right Cylinder?
Choose the SCT63X80X5 when your process requires a short 5 mm positioning step alongside an 80 mm primary stroke, avoiding the complexity of external hard stops. If you need higher force, stepping up to the 80 mm bore provides 2513 N of push per section at the same pressure. For a drop-in replacement, match the 63 mm bore, both the 80 mm and 5 mm strokes, PT port thread, and basic mounting configuration exactly.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 80 + 5 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 SCT63X80X5 FAQ
This tandem cylinder reaches four discrete rod positions: fully retracted (0 mm), the first section extended (5 mm), the second section extended (80 mm), and both sections extended together for a total travel of 85 mm.
It combines two strokes on a single common rod, guaranteeing inherent alignment between the 5 mm and 80 mm positions without external brackets or couplers. This saves installation space and simplifies the pneumatic circuit to just two valve ports.
