Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X160X200S
The AirTAC Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X160X200S is a genuine double-acting MULTI-POSITION (tandem) air cylinder: two piston sections of 160mm and 200mm give 4 controllable stop positions across a 360mm total travel, with a Ø32mm bore, PT1/8 ports and adjustable end cushioning.

About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X160X200S
The SCT32X160X200S is a 32 mm bore multi-position cylinder that delivers four fixed rod positions by combining two piston sections on a single axis. With strokes of 160 mm and 200 mm, the accessible stops are 0 mm, 160 mm, 200 mm, and the full 360 mm extension, giving machine designers a compact way to handle two distinct feed lengths without dual cylinders.
Each section generates 402 N of push force at 0.5 MPa, rising to 724 N at the maximum operating pressure of 0.9 MPa, and uses a 12 mm diameter piston rod with an M10x1.25 thread. The integrated -S magnet allows CMSG, DMSG, or EMSG sensors to be clamped directly onto the tie-rod barrel for end-of-stroke or mid-position confirmation. The body length A(SCT) is 233 mm, and the adjustable air cushion at each end is 21 mm long, helping to manage kinetic energy at higher cycle rates.

| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X160X200S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø32 mm |
| Stroke 1 / Stroke 2 | 160 / 200 mm |
| Total travel | 360 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) | 160 mm |
| P2 (section 2) | 200 mm |
| P3 (both extended) | 360 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 SCT32X160X200S Is Used
Two-Stage Part Diverting
A conveyor gate uses the 160 mm stroke for a primary divert and the 200 mm stroke for a secondary reject lane, with sensors at each position confirming the gate angle.
Dual-Depth Press Feeding
The rod advances a workpiece to a first press station at 200 mm, then retracts to a 160 mm offset for a second shallow forming operation before returning home.
Multi-Stop Assembly Indexing
An assembly fixture shifts between a load position (0 mm), a glue-dispense stop (160 mm), a component placement stop (200 mm), and a full-forward curing station (360 mm).
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X160X200S the Right Cylinder?
This 4-position tandem unit is a space-saving alternative to mounting two separate 32 mm cylinders with external hard stops, as it guarantees the relative distance between the two intermediate positions is mechanically fixed. When the 402 N push force per section is insufficient, stepping up to a 40 mm bore SCT provides 628 N of thrust at the same 0.5 MPa supply pressure. For direct replacement, match the 32 mm bore, the two strokes of 160 mm and 200 mm, the PT port thread, and the -S magnet option; the basic mounting style means no additional brackets are included, so existing foot or flange mounts must be ordered separately if needed.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 160 + 200 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 SCT32X160X200S FAQ
It provides four distinct mechanical stop positions: fully retracted (0 mm), the first section extended (160 mm), the second section extended (200 mm), and both sections extended for the total travel (360 mm). These are fixed by the cylinder’s internal construction and are not infinitely adjustable.
No. Like all standard pneumatic cylinders, the SCT32X160X200S will drift or drop if pressure is exhausted from a section. If a load must be held securely at an intermediate stop without live air, an external pilot-operated check valve or a mechanical rod lock is required.
