About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT40X300X300SN
The SCT40X300X300SN is a tandem multi-position cylinder delivering three fixed rod positions: 0 mm, 300 mm, and 600 mm total travel. Each piston section provides a push force of 628 N at 0.5 MPa, making it suitable for sorting or diverting tasks requiring repeatable intermediate stops without complex controls.
This model features a 16 mm diameter rod and PT1/4 ports, with a 21 mm adjustable air cushion on each end for smooth deceleration. The built-in magnet allows direct mounting of CMSG/DMSG sensors for position feedback, while the NBR seals suit standard industrial environments.
Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT40X300X300SN Technical Specifications
| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT40X300X300SN |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø40 mm |
| Stroke 1 / Stroke 2 | 300 / 300 mm |
| Total travel | 600 mm |
| Stop positions | 3 positions |
| Acting type | Double acting (tandem, multi-position) |
| Port size | PT1/4 |
| Rod thread | M12×1.25 |
| 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 (3)
| Position | Rod extension |
|---|---|
| P0 (retracted) | 0 mm |
| P1 (section 1) | 300 mm |
| P2 (both extended) | 600 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 (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 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 SCT40X300X300SN Is Used
3-Position Diverter Gate
Uses the 0, 300, and 600 mm stops to route packages to three separate conveyor lanes. The built-in magnet confirms gate position at each stop.
Multi-Stop Material Feed
Advances material in two precise 300 mm increments for a two-step stamping or cutting process, using sensor feedback for cycle start.
Two-Depth Assembly Press
Provides a partial 300 mm insertion depth and a full 600 mm seating depth. The 628 N per-section force handles light to medium press-fit operations.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT40X300X300SN the Right Cylinder?
Choose the SCT when your application needs three fixed, repeatable stop points from a single compact unit, avoiding the cost and complexity of two separate cylinders with external stops. For higher thrust, consider stepping up to the 50 mm bore SCT, which delivers 982 N of push force per section at 0.5 MPa. This SCT40X300X300SN directly replaces any AirTAC SCT of the same 40 mm bore, 300 mm and 300 mm strokes, PT ports, and built-in magnet.
With a 300 mm stroke per section, ensure the load is guided to prevent rod bending or side-load wear. The cylinder's basic mounting style means you will need to provide a rigid, flat mounting surface or select an accessory bracket from the FA, FB, CA, CB, or LB range.
Multi-position checklist
- ✓ Need 3 repeatable stops?
- ✓ Section strokes 300 + 300 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 SCT40X300X300SN FAQ
It has three distinct rod positions: fully retracted (0 mm), the first section extended (300 mm), and both sections extended for full travel (600 mm). These stops are achieved by pressurizing one or both cylinder sections.
Yes, it is a direct replacement for setups using two 40 mm bore cylinders to achieve a 300 mm and a 600 mm stop. It simplifies plumbing and mounting. Ensure the replacement matches the 300 mm and 300 mm strokes, PT ports, and the S magnet option for sensor compatibility.
