About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X30X30S
The SCT63X30X30S is a double-acting multi-position tandem cylinder that provides three distinct, repeatable rod positions: fully retracted (0 mm), 30 mm, and 60 mm. Each piston section delivers a push force of 1559 N at 0.5 MPa, and the unit is built with a 20 mm diameter rod and PT1/4 ports. The integrated magnet allows direct mounting of CMSG/DMSG/EMSG sensors for position feedback.
With a 28 mm air cushion at each end and a body length A of 249 mm, this cylinder is designed for reliable deceleration and a compact footprint. It is a genuine AirTAC product, ideal for applications requiring fixed intermediate stops without complex electronic controls.
Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X30X30S Technical Specifications
| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X30X30S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø63 mm |
| Stroke 1 / Stroke 2 | 30 / 30 mm |
| Total travel | 60 mm |
| Stop positions | 3 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 (3)
| Position | Rod extension |
|---|---|
| P0 (retracted) | 0 mm |
| P1 (section 1) | 30 mm |
| P2 (both extended) | 60 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 SCT63X30X30S Is Used
3-Position Diverter Gate
Actuates a gate on a conveyor to three fixed positions—closed, divert to lane A (30 mm), and divert to lane B (60 mm)—using simple pneumatic controls and no servo motor.
Two-Depth Pressing
Provides two distinct pressing depths in a small assembly fixture, such as a partial insertion at 30 mm and a full press at 60 mm, with sensor confirmation at each stop via the built-in magnet.
Multi-Stop Clamping
Clamps workpieces of two different thicknesses on a machining center, retracting fully for part changeover, extending 30 mm for thin stock, and 60 mm for thick stock.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X30X30S the Right Cylinder?
Choose the SCT63X30X30S when a pneumatic system needs three fixed mechanical stops from a single, compact assembly, avoiding the cost and complexity of two separate cylinders and external hard stops. For higher force requirements, stepping up to the 80 mm bore provides 2513 N of push per section at the same 0.5 MPa pressure. This model is a direct replacement for any AirTAC SCT63X30X30S with a basic mount, PT threads, and the -S magnet option.
Multi-position checklist
- ✓ Need 3 repeatable stops?
- ✓ Section strokes 30 + 30 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 SCT63X30X30S FAQ
This model has 3 discrete mechanical stop positions. The rod can be positioned at 0 mm (fully retracted), 30 mm (first section extended), and 60 mm (both sections extended for total travel).
The SCT integrates two piston sections on a single rod line, guaranteeing coaxial alignment and reducing installation space. It replaces two individual SC63X30 cylinders with a single, pre-aligned unit that is controlled by pressurizing either or both of its sections.
