About the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X50X50SLB
The SCT32X50X50S is a tandem multi-position cylinder that delivers three fixed rod positions: fully retracted (0 mm), 50 mm, and the combined 100 mm stroke. Built on a 32 mm bore with a 12 mm diameter rod and PT1/8 ports, each piston section generates approximately 402 N of push force at 0.5 MPa, rising to 724 N at the maximum operating pressure of 0.9 MPa.
This model includes a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors, enabling precise end-of-stroke or mid-position confirmation. The LB foot mount provides stable axial surface mounting, and the standard TPU seals suit operating temperatures from -20 to +70 °C. The body length A(SCT) is 233 mm, and the adjustable pneumatic cushion on each section is 21 mm long, helping to manage end-of-stroke impact in compact sorting or diverting tasks.

| Model | Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X50X50SLB |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø32 mm |
| Stroke 1 / Stroke 2 | 50 / 50 mm |
| Total travel | 100 mm |
| Stop positions | 3 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 (3)
| Position | Rod extension |
|---|---|
| P0 (retracted) | 0 mm |
| P1 (section 1) | 50 mm |
| P2 (both extended) | 100 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 SCT32X50X50SLB Is Used
3-Position Diverter Gate
Uses the 0, 50, and 100 mm stops to route small packages or components into three separate lanes on a conveyor, triggered by the CMSG sensors mounted on the barrel.
Two-Depth Press Insertion
Provides a partial advance at 50 mm for pre-location and a full 100 mm stroke for final insertion, eliminating the need for a second actuator in light assembly fixtures.
Multi-Stop Part Feeding
Positions a stop pin at three discrete heights to control the feed of blanks into a stamping die, with the magnet sensors confirming each position before the press cycles.
Is the Airtac SCT32-63 Multi-Position Tandem Air Cylinder SCT32X50X50SLB the Right Cylinder?
Choose the SCT32X50X50S when your application needs three distinct mechanical stops without the complexity of two separate cylinders and external hard stops. The tandem design keeps the footprint compact, and the 100 mm total travel is ideal for light diverting gates or two-depth component insertion. If you need more force per section, step up to the 40 mm bore, which provides 628 N of push at 0.5 MPa.
For a direct replacement, match the 32 mm bore, both 50 mm section strokes, PT port thread, LB foot mounting, and the -S magnet option. When either stroke exceeds 300 mm, consider external guide rods to protect the 12 mm rod from side-load deflection. The built-in magnet lets you add reed or solid-state sensors without additional brackets, simplifying position feedback integration.
Multi-position checklist
- ✓ Need 3 repeatable stops?
- ✓ Section strokes 50 + 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 SCT32X50X50SLB FAQ
Because both section strokes are 50 mm, this model provides three distinct mechanical positions: 0 mm (fully retracted), 50 mm (first section extended), and 100 mm (both sections extended, total travel).
Yes, provided the original cylinder also has a 32 mm bore, both strokes are 50 mm, and it uses PT ports. This model adds the built-in magnet (-S) and LB foot mount; ensure your mounting surface and sensor setup are compatible with these features.
