Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X200X70
The AirTAC Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X200X70 is a genuine double-acting MULTI-POSITION (tandem) air cylinder: two piston sections of 200mm and 70mm give 4 controllable stop positions across a 270mm total travel, with a Ø32mm bore, PT1/8 ports and adjustable end cushioning.

About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X200X70
The SCT32X200X70 is a double-acting tandem cylinder that delivers four fixed rod positions by combining two piston sections on a single axis. With strokes of 200 mm and 70 mm, the reachable stops are fully retracted (0 mm), 70 mm, 200 mm, and the total extended travel of 270 mm. Each section uses a 12 mm diameter rod and generates 402 N of push force at 0.5 MPa, scaling to 724 N at the maximum operating pressure of 0.9 MPa.
This 32 mm bore multi-position actuator uses PT1/8 ports and an M10x1.25 rod thread, with a body length A(SCT) of 233 mm. The integral adjustable air cushion on each section decelerates the piston at end-of-stroke, but the cylinder does not lock—if a load must be held at one of the four positions without live pressure, an external pilot-operated check valve or rod brake is required.

| Total travel | 270 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) | 200 mm |
| P2 (section 2) | 70 mm |
| P3 (both extended) | 270 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 SCT32X200X70 Is Used
Two-Stage Diverter Gate
Operates a sorting gate with three open positions plus fully closed. The 70 mm stroke partially opens the gate for small items, while the 200 mm stroke creates a wide path for larger packages, and the combined 270 mm travel provides a full bypass route.
Multi-Depth Pressing
Provides two distinct pressing depths in a light assembly fixture. The first section extends 70 mm for a pre-load or shallow insert, and the second section adds 200 mm of travel for a full-depth seating operation, all from a single compact actuator.
Sequential Part Feeding
Controls a two-stage pusher on a conveyor line. The cylinder extends to 70 mm to separate a single component from a stack, then travels the full 270 mm to transfer the part into the next station, using the 200 mm intermediate position as a waiting stage.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X200X70 the Right Cylinder?
Choose the SCT32X200X70 when a process needs four distinct mechanical stops without the complexity of two separate cylinders and external hard stops. The tandem design saves space and eliminates the need to synchronize two actuators. If the 402 N push force per section (at 0.5 MPa) is insufficient for the load, consider stepping up to the SCT40 series, which provides 628 N per section at the same pressure. For replacement, match the 32 mm bore, both the 200 mm and 70 mm strokes, PT port thread, and basic mounting configuration. Note that the 200 mm stroke section is substantial; ensure the rod is guided if significant side loads are present to prevent bending.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 200 + 70 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 SCT32X200X70 FAQ
This tandem cylinder provides four discrete mechanical stop positions: 0 mm (fully retracted), 70 mm (first section extended), 200 mm (second section extended), and 270 mm (both sections extended for total travel). The positions are fixed by the two stroke lengths and are selected by pressurizing the appropriate cylinder sections.
Yes, it is designed to replace two individual cylinders in applications requiring up to four fixed stops. The SCT integrates both strokes on a common rod line, which saves mounting space and eliminates the need for external alignment. For a direct replacement, ensure the new SCT matches the 32 mm bore, the exact 200 mm and 70 mm strokes, and the PT port thread.
