Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT40X150X160S
The AirTAC Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT40X150X160S is a genuine double-acting MULTI-POSITION (tandem) air cylinder: two piston sections of 150mm and 160mm give 4 controllable stop positions across a 310mm total travel, with a Ø40mm bore, PT1/4 ports and adjustable end cushioning.

About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT40X150X160S
The SCT40X150X160S is a double-acting tandem cylinder that delivers four fixed rod positions—0 mm, 150 mm, 160 mm, and the full 310 mm travel—from its two piston sections. With a 16 mm diameter rod and PT1/4 ports, each section generates 628 N of push force at 0.5 MPa, making it a precise multi-stop actuator for sorting or diverting tasks.
This model includes a built-in magnet, allowing CMSG, DMSG, or EMSG sensors to clamp directly onto the tie-rod barrel for reliable end-of-stroke or mid-position sensing. The cylinder body length A(SCT) is 235 mm, and the adjustable air cushion on each section smooths deceleration across all four stop points.
Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT40X150X160S Technical Specifications
| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT40X150X160S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø40 mm |
| Stroke 1 / Stroke 2 | 150 / 160 mm |
| Total travel | 310 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) | 150 mm |
| P2 (section 2) | 160 mm |
| P3 (both extended) | 310 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 SCT40X150X160S Is Used
Two-Way Part Diverting
Uses the 150 mm and 310 mm positions to route parts to two separate conveyor lanes from a single infeed point.
Dual-Depth Pressing
Provides a 150 mm approach stroke and a 160 mm secondary depth for a two-stage insertion or pressing operation.
Staggered Stop Gate
The 0 mm, 150 mm, and 160 mm positions create a three-height gate for releasing different pallet sizes in a gravity feed system.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT40X150X160S the Right Cylinder?
Choose this four-position SCT when a process needs two independent, unequal extension points without the complexity of two separate cylinders and external hard stops. The 150 mm and 160 mm strokes provide closely spaced yet distinct positions, ideal for two-step feeding or depth selection. If higher force is required, stepping up to the 50 mm bore provides 982 N of push per section at the same pressure.
For replacement, match the 40 mm bore, both 150 mm and 160 mm section strokes, PT port thread, and the -S magnet option. The basic mounting configuration accepts standard SCT foot (LB) or flange (FA/FB) accessories if a fixed mount is later needed. Note that with a combined travel of 310 mm, ensure the load is guided if side forces are present to prevent rod bending.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 150 + 160 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 SCT40X150X160S FAQ
It provides four discrete rod positions: fully retracted (0 mm), the first section extended (150 mm), the second section extended (160 mm), and both sections extended for the total travel of 310 mm.
Yes, in applications where you need two fixed, unequal extension points from a single rod line. It eliminates the need for mounting and aligning two separate cylinders and their external stops, provided the per-section force of 628 N push at 0.5 MPa is sufficient for both positions.
