About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X35X45
The SCT32X35X45 tandem cylinder delivers four distinct mechanical stop positions—0 mm, 35 mm, 45 mm, and 80 mm total travel—from a single tie-rod body with a 12 mm rod. Each piston section generates 402 N of push force at 0.5 MPa, giving designers a repeatable, air-piloted alternative to complex multi-actuator setups for light sorting and diverting tasks.
This double-acting multi-position unit uses PT1/8 ports and has a 21 mm adjustable air cushion at each end to manage end-of-stroke impact. The body length A(SCT) is 233 mm, making it a space-efficient choice for machines that need two fixed intermediate positions without adding extra cylinders or external hard stops.
Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X35X45 Technical Specifications
| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X35X45 |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø32 mm |
| Stroke 1 / Stroke 2 | 35 / 45 mm |
| Total travel | 80 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) | 35 mm |
| P2 (section 2) | 45 mm |
| P3 (both extended) | 80 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 SCT32X35X45 Is Used
3-Way Part Diverting
Uses the 0 mm, 35 mm, and 80 mm positions to guide small components down three separate chutes on a packaging line, replacing two standard cylinders with one compact unit.
Two-Depth Label Press
The 45 mm and 80 mm extended positions apply two different pressing depths for labels on stepped product surfaces, ensuring consistent adhesion without over-travel.
Multi-Stop Gate Control
Provides four gate openings (closed, 35 mm, 45 mm, fully open at 80 mm) to meter different-sized cartons onto a conveyor, controlled simply by sequencing pressure to each section.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X35X45 the Right Cylinder?
Choose the SCT32X35X45 when your sequence requires four fixed positions and the load is within the 402 N per-section push capacity. If you need more force, stepping up to the SCT40 series provides 628 N of push per section at the same 0.5 MPa. For replacement, match the 32 mm bore, both strokes (35 mm and 45 mm), PT thread, and basic mounting to ensure a drop-in fit.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 35 + 45 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 SCT32X35X45 FAQ
It provides four discrete mechanical stop positions: fully retracted (0 mm), first section extended (35 mm), second section extended (45 mm), and both sections extended for the total travel of 80 mm. The positions are fixed by the two stroke lengths.
Yes, it is designed to replace two individually mounted SC32 cylinders in applications needing three or four fixed positions. Ensure the replacement matches the 32 mm bore, both 35 mm and 45 mm strokes, PT port thread, and basic mounting configuration.
