About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X85X75S
The SCT32X85X75S is a tie-rod multi-position cylinder that delivers four distinct rod positions—0 mm, 75 mm, 85 mm, and the full 160 mm total travel—by pressurising its two tandem piston sections independently. Each 32 mm bore section generates 402 N of push force at 0.5 MPa, driven through a 12 mm diameter rod, making it a compact solution for light-duty sorting or diverting tasks.
A built-in magnet (denoted by the -S suffix) runs the length of the barrel, allowing CMSG or DMSG solid-state sensors to clamp directly on for non-contact position feedback at each stop. The cylinder body measures 233 mm in its base length and uses PT1/8 ports with an M10x1.25 rod thread, offering a genuine AirTAC tandem assembly for machines that need more than two fixed positions from a single pneumatic axis.
Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X85X75S Technical Specifications
| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X85X75S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø32 mm |
| Stroke 1 / Stroke 2 | 85 / 75 mm |
| Total travel | 160 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) | 85 mm |
| P2 (section 2) | 75 mm |
| P3 (both extended) | 160 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 SCT32X85X75S Is Used
Four-Position Diverter Gate
Actuates a chute or flap to four fixed angles for routing packages to separate lanes on a conveyor, using the 0, 75, 85, and 160 mm rod positions.
Multi-Stop Part Feeding
Advances a pusher bar to three distinct depths for staging different-sized components at an assembly station, with sensor confirmation at each stop via the built-in magnet.
Two-Depth Clamping Fixture
Provides two distinct clamping pressures or jaw openings for a single fixture, using the 75 mm and 85 mm strokes for different part families in a machining cell.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X85X75S the Right Cylinder?
Choose this SCT when a single actuator must deliver four hard stops without the complexity of two separate cylinders and external brackets. If the 402 N push force per section at 0.5 MPa is slightly below your need, stepping up to the 40 mm bore SCT40 series raises the push to 628 N per section. For replacement, match the 32 mm bore, both the 85 mm and 75 mm strokes, PT port thread, and the integrated magnet; this model uses a basic mount, so confirm your mounting brackets separately if needed.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 85 + 75 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 SCT32X85X75S FAQ
It has four discrete mechanical stops at 0 mm (fully retracted), 75 mm, 85 mm, and 160 mm (fully extended). The 75 mm and 85 mm stops are achieved by pressurising each piston section individually, while the 160 mm stop requires both sections pressurised.
Yes, the -S suffix indicates a built-in magnetic ring on the piston. This lets you mount CMSG reed switches or DMSG/EMSG solid-state sensors directly onto the cylinder barrel's sensor slots to detect each of the four positions.
