About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X200X150
The AirTAC SCT63X200X150 is a double-acting tandem cylinder engineered for applications requiring four precise, repeatable stop positions. By combining a 200 mm front-section stroke with a 150 mm rear-section stroke, the rod achieves distinct positions at 0 mm (fully retracted), 150 mm, 200 mm, and the total travel of 350 mm. Each piston section delivers a push force of 1559 N at 0.5 MPa, and the 20 mm diameter piston rod is supported by a 28 mm adjustable air cushion in each section for end-of-stroke deceleration.
This tie-rod cylinder body has a base length A(SCT) of 249 mm, providing a rigid structure for inline multi-stop tasks. The standard TPU seals offer reliable operation in a temperature range of -20 to +70 °C. With PT1/4 ports and an M16x1.5 rod thread, it integrates easily into pneumatic circuits where a single cylinder must replace complex multi-actuator setups for sequencing or diverting functions.

| Bore size | Ø63 mm |
| Stroke 1 / Stroke 2 | 200 / 150 mm |
| Total travel | 350 mm |
| Stop positions | 4 positions |
| Acting type | Double acting (tandem, multi-position) |
| Port size | PT1/4 |
| Rod thread | M16×1.5 |
| 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, 28 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) | 200 mm |
| P2 (section 2) | 150 mm |
| P3 (both extended) | 350 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 (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1559 N | 1402 N |
| 0.7 MPa | 2182 N | — |
| Max (@1.0 MPa) | 318 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 SCT63X200X150 Is Used
Two-Stage Part Diverting
Operates a diverter gate with four positions: home, divert to lane A (150 mm), divert to lane B (200 mm), and a purge/cleanout position at full 350 mm extension.
Multi-Depth Pressing
Provides three distinct pressing depths for assembly operations. The rod stops at 150 mm for a pre-press, 200 mm for a forming stage, and 350 mm for final insertion, all from one compact cylinder.
Sequential Part Feeding
Controls a multi-stop escapement mechanism. The 150 mm stroke releases one part, the 200 mm stroke releases a second, and the full 350 mm stroke clears the track, simplifying the feeding logic.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X200X150 the Right Cylinder?
Select the SCT63X200X150 when a process requires the rod to stop at two intermediate points and full extension without using external hard stops or multiple cylinders. This model is ideal where the 0.5 MPa push force of 1559 N per section matches the load, offering a clean, self-contained solution. If the application demands higher force, consider stepping up to the SCT80 bore, which provides 2513 N of push per section at the same pressure; for a lighter load, the SCT50 bore delivers 982 N.
For a direct replacement, match the 63 mm bore, the 200 mm and 150 mm strokes, PT thread, and basic mounting. If a sensor is needed for position confirmation, the SCT63X200X150-S variant with a built-in magnet allows CMSG or DMSG sensors to be clamped directly onto the tie-rod barrel. With a 200 mm stroke on the front section, ensure the load is guided to prevent side-loading and rod bending during extension.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 200 + 150 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 SCT63X200X150 FAQ
This tandem cylinder provides four discrete rod positions: 0 mm (fully retracted), 150 mm (rear section extended), 200 mm (front section extended), and 350 mm (both sections extended). The positions are fixed by the two stroke lengths and are selected by pressurizing the appropriate cylinder sections.
The force is generated per actuated piston section. At 0.5 MPa, each section provides a push force of 1559 N and a pull force of 1402 N. The total force does not double when both sections are pressurized; instead, the rod moves to the 350 mm position with the same 1559 N push force acting on the load.
