About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X40X50S
The SCT63X40X50S is a double-acting multi-position tandem cylinder that delivers four fixed rod positions: fully retracted (0 mm), 40 mm, 50 mm, and the total travel of 90 mm. Each 63 mm bore piston section generates a push force of 1559 N at 0.5 MPa, making it suitable for sorting or diverting tasks that require distinct intermediate stops without complex controls.
This model includes a built-in magnet, allowing direct mounting of CMSG, DMSG, or EMSG sensors along the tie-rod barrel for reliable position feedback. The 20 mm diameter piston rod and 28 mm adjustable air cushion at each end help manage kinetic energy effectively. The body length A(SCT) is 249 mm, providing a compact footprint for multi-stop linear actuation.
Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X40X50S Technical Specifications
| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X40X50S |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø63 mm |
| Stroke 1 / Stroke 2 | 40 / 50 mm |
| Total travel | 90 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) | 40 mm |
| P2 (section 2) | 50 mm |
| P3 (both extended) | 90 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 SCT63X40X50S Is Used
Two-Stage Diverter Gate
Uses the 40 mm and 50 mm strokes to route packages to two separate conveyor lanes from a single retracted home position.
Multi-Depth Pressing
Achieves two distinct pressing depths in a compact assembly station, first at 40 mm for insertion and then at 90 mm for final seating.
Sequential Part Feeding
Advances components in two controlled steps, stopping at 40 mm for inspection and 90 mm for placement, with sensor confirmation at each position.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT63X40X50S the Right Cylinder?
Selecting the SCT63X40X50S provides four discrete mechanical stops from a single actuator, eliminating the need for two separate cylinders and external hard stops. If your application requires higher force, consider stepping up to the 80 mm bore, which provides 2513 N of push per section at 0.5 MPa. For a direct replacement, ensure the substitute matches the 63 mm bore, both 40 mm and 50 mm strokes, PT port thread, and the integrated magnet sensor option.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 40 + 50 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 SCT63X40X50S FAQ
This tandem cylinder provides four discrete mechanical stops: 0 mm (fully retracted), 40 mm (first section extended), 50 mm (second section extended), and 90 mm (both sections extended).
It integrates two piston sections on a single common rod, guaranteeing fixed 40 mm and 50 mm intermediate stops without external brackets or couplers. This reduces alignment issues and overall installation space compared to a dual-cylinder setup.
