About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X80X50S
The SCT32X80X50S is a tie-rod multi-position cylinder that delivers four discrete rod positions—0 mm, 50 mm, 80 mm, and the full 130 mm combined stroke—by pressurising its two piston sections independently. Each section generates 402 N of push force at 0.5 MPa (563 N at 0.7 MPa), driven through a 12 mm rod with PT1/8 ports and a 21 mm adjustable air cushion for end-of-stroke deceleration.
A built-in magnet is included with this model, allowing CMSG, DMSG, or EMSG sensors to be clamped directly onto the barrel for non-contact position feedback. The body length A is 233 mm, and the cylinder operates on standard 40 µm filtered air across a pressure range of 0.15–1.0 MPa and temperatures from -20 to +70 °C.

| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X80X50S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø32 mm |
| Stroke 1 / Stroke 2 | 80 / 50 mm |
| Total travel | 130 mm |
| Stop positions | 4 positions |
| Acting type | Double acting (tandem, multi-position) |
| Port size | PT1/8 |
| Rod thread | M10×1.25 |
| 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) | 80 mm |
| P2 (section 2) | 50 mm |
| P3 (both extended) | 130 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 (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 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 SCT32X80X50S Is Used
Two-Way Diverter Gate
Extend to 50 mm for one lane, 80 mm for a second, or 130 mm to close both paths in a compact conveyor sorting head.
Multi-Depth Label Press
Apply labels at two controlled depths (50 mm and 80 mm) on a single product line, with full retraction for part clearance.
Staged Component Insertion
Insert a pin to a partial depth of 50 mm, then drive to 80 mm for final seating, using the 130 mm position for a secondary push operation.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X80X50S the Right Cylinder?
Choose this 4-position tandem unit when a single actuator must index between two distinct mid-stroke locations and full extension without the complexity of two separate cylinders and external hard stops. If you need higher force, stepping up to the 40 mm bore provides 628 N of push per section at 0.5 MPa. For direct drop-in replacement, match the 32 mm bore, both strokes (80 mm and 50 mm), PT port thread, basic mounting, and the -S magnet option. With a combined stroke of 130 mm, rod deflection is minimal under axial loads, but always align the load to prevent side forces on the 12 mm rod.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 80 + 50 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 SCT32X80X50S FAQ
This tandem cylinder provides four discrete rod positions: fully retracted (0 mm), stroke1 extended (50 mm), stroke2 extended (80 mm), and both sections extended for the total travel of 130 mm. Each stop is fixed by the mechanical stroke of the two piston sections and is selected by pressurising the corresponding air port.
Yes, in applications requiring two fixed intermediate stops and a total extension, the SCT32X80X50S replaces two 32 mm bore SC cylinders with 50 mm and 80 mm strokes, eliminating the need for external brackets and alignment. Ensure the replacement matches the bore, both stroke lengths, PT ports, and the -S magnet option if sensor feedback is required.
